(00:00):
Forget the scoreboard for a second.
Forget who lifted the trophy. Look closer.
Look at the invisible river of data flowing off every single
player. That right there, that's the
real pulse of elite competition today.
Welcome to the deep dive. We're not here just to rehash
results. No, we're plugging in.
We're strapping on the sensors, and we're zooming right into the
heart of the beautiful game. We're here to dissect the
(00:23):
incredible. Almost surgical way data science
is rewriting the rules of human performance.
It's not just skill anymore, is it?
It's muscle, it's metabolism, and it's machine learning all
rolled into one. Absolutely.
It's the ultimate blend of competition and code, really.
And we're using a recent major global youth tournament as our
backdrop. You know, these events are
(00:44):
intense pressure cookers. The margins between winning and
going home, they're unbelievablythin.
Razor thin. And now those margins aren't
just moments of brilliance. They're measured in
milliseconds, in tiny variationsand physiological readings.
So our mission today is to get past the headlines, past the
final scores and really understand the the complex
tools, the integrated systems that are basically defining
(01:06):
success at this top level. Now we're going right to the
performance lab, so to speak, todecode this fusion of, well, raw
talent and super specific analytics.
Exactly. And just to paint the picture,
you have to appreciate how incredibly tight this
environment is. When you have teams this evenly
matched in terms of raw talent, success often just boils down to
(01:28):
1 tiny edge in preparation, or maybe even a single decimal
point in some complex tiebreakerrule.
Oh, the tiebreakers. You really feel the the sting of
it when you see a team's entire tournament decided not just by
wins or losses, but by these really quite intricate rules
around goal difference. We saw that play out, didn't we,
with Egypt's U20 team? Yeah, it was tough to watch.
They fought incredibly hard. They even pulled off a really
(01:50):
spirited 2 one win against Chile, the hosts in their last
group game that gave them three points, but that was it for
them. Their journey ended right there.
The sheer complexity of the group stage tiebreakers, that
was their undoing. It's the fine print that gets
you, isn't it? They ended up with a goal
difference of -2 OK, and they'd scored three goals across their
matches and that, that single detail was everything.
(02:13):
They were out ranked sixth amongall the 3rd place teams.
And why? Because Australia, who also had
a -2 goal difference, had managed to score four goals,
just one more goal than Egypt. One goal.
That's the difference between advancing and booking flights
home. It just hammers home that at
this level, your preparation, your execution, it has to be
almost perfect. It really does.
(02:34):
And, you know, that was Egypt's fourth early exit at this stage
in this specific tournament series, going back to 91 one,
2005, 2013. It shows how hard it is to
consistently breakthrough. Their best finish, remember, was
third place way back in 2001. Those tiny margins, they can be
brutal. But it wasn't all heartbreak for
African teams, it actually showed the strength building in
their youth programs right now. We saw Morocco, South Africa and
(02:57):
Nigeria all make it through to the knockout rounds. 3 teams in
the round of 16. That's a strong showing.
Definitely. And they faced some really tough
matchups too. Morocco drew South Korea,
Nigeria had this huge rematch against Argentina.
You might remember Nigeria actually beat them two nil in a
previous quarterfinal. So there was history there.
Right. And South Africa, they really
showed what they were made of inthe group stage.
(03:19):
They got through too. Now, there was a little bit of
confusion in the reports about exactly who they played next.
Some said Columbia, others Norway, but honestly the key
thing is how they got there. Their performance in Group E was
well it was a master class in resilience and navigating those
tricky tiebreaker situations. Oh, absolutely.
South Africa pulled off a brilliant 21 comeback victory
(03:41):
against the United States. They actually went down one nil
early on. Noah Cobb scored for the US, but
South Africa, they just didn't buckle.
No, they hit back pretty quickly.
Their pressure forced an own goal from the US defender Joshua
Weinter that level things up. And then just before halftime,
Golmawa Kakana finished it off, converting a really smart
(04:01):
cutback. That fightback really summed up
their group stage. But here's the really
fascinating part, the bit that shows how complex modern
tournament football is. Even though the US lost that
game to South Africa, the US still ended up winning Group E
South Africa finished second. How?
Because of the tiebreakers again.
Earlier in the group, the US hadpulled off a massive 3 nil upset
(04:24):
against France. Goals from Xavier Gozo, Brooklyn
Reigns, Marco Zambrano, Delgado That big win, that goal
difference boost against France was ultimately what separated
them when all the head to head calculations were done between
the Tide teams. It's mind bending, isn't it?
It really is. And that whole Group E
situation, it perfectly capturesour theme today, doesn't it?
(04:44):
The tiny difference between going home early like Egypt, or
winning the group like the US. It can come down to a single
performance against a totally different team earlier on.
All filter through layers of statistical rules.
It just shows that success now isn't just about coaching
skills. It demands institutional
brainpower and analytical innovation too.
That's a perfect transition. Let's shift gears now from the
(05:07):
drama playing out on the pitch itself and look at the sort of
the institutional framework thatunderpins elite football today.
The watchers and the rules, as you put it.
These big tournaments, they aren't just talent showcases
anymore. They're active labs for trying
out new ideas, both in how teamstrain and how the game is
officiated. OK, first up, let's talk about
the intelligence unit, if you will, the technical study group,
(05:31):
the TSG. So if the teams are using data
to get better, the TSG is using data to what?
Make coaching better globally. What's their actual mission?
It's pretty comprehensive actually.
The TS GS job is to deliver really cutting edge, systematic
analysis of every single match in the tournament, all 52 of
them. They're looking for tactical
trends, new formations, any kindof unique innovation.
(05:52):
Teams are trying and importantly, they're the ones
who select the individual award winner, like the Golden Ball for
the best player. It's not just casual
observation, it's high level football, intelligence gathering
and synthesis. And the people involved tell you
everything about how seriously this is taken.
It's led by Pascal Zuberviller, FIFA's senior football expert.
Former Swiss international goalkeeper right famously didn't
(06:14):
concede a single goal in open play during the entire 2006
world. Cup, that's the one.
Pretty good credentials for analyzing defense and game
management. You'd think so.
And he's joined by really interesting mix of expertise.
You've got Corinne Dyecker, former French defender, then
manager, notably the first womanto manage a men's professional
team in France's league, too. Huge experience there.
(06:37):
Wow. OK.
Then there's Marcin Dorna, who'sa Polish specialist really
focused on youth development systems, and Marcelo Jarrah, a
former Chilean forward who's gone into high level coaching.
So you get this great blend of perspectives.
Goalkeeping, management, tactics, youth development,
Attacking play, they're coveringall the angles and this
knowledge doesn't just stay within FIFA, does it?
No, that's key. The insights they gather, the
(06:59):
trends they identify, it's all shared globally through the FIFA
Training Center platform. The idea is to sort of
democratize that cutting edge knowledge, help coaches
everywhere understand what elitesuccess looks like right now.
So this drive for kind of intellectual games, for smarter
football, it's mirrored by a similar push for games in
(07:20):
fairness and accuracy on the pitch itself.
We saw this tournament used as atesting ground for a new
officiating system, right? Football video support or FES?
That's right, FES. It's essentially an alternative
to the standard VAR system we'reused to seeing.
It was trialled here specifically to look at those
big match changing moments, potential clear and obvious
errors related to goals, penalties, direct red cards or
(07:42):
cases of mistaken identity. But the really interesting twist
is how it involves the coaches. Yeah, this part is fascinating.
It gives the power back to the benches in a way.
It completely changes the dynamic.
Instead of waiting for the VAR officials to initiate a review,
FBS gives each team's coach 2 challenges per match.
They signal their challenge using a designated blue or maybe
(08:04):
purple card to appeal a specificrefereeing decision.
And here's the clever bit. If their challenge is
successful, meaning the video review actually overturns the
referee's original call, they get to keep that challenge.
They don't lose it. Exactly.
But if the review confirms the ref's decision if the coach was
wrong, then they lose one of their two challenges for the
(08:25):
rest of the match. So it becomes this high stakes
tactical decision for the coach,doesn't it?
Is this call important enough torisk using a challenge I might
desperately need later in the game?
Precisely. And we saw it used effectively
almost straight away. Yeah, tell us about that first
successful challenge. It happened in Morocco's two nil
victory over Spain. The Moroccan coach Muhammad Wabi
(08:45):
used his challenge card, his blue card in this case, to
contest a penalty that had just been awarded against his team.
Very the referee went to the monitor, reviewed the incident
based on the coaches challenge and ultimately agreed.
The penalty decision was overturned and because Morocco's
challenge was successful, they kept their full quota of
challenges. That single intervention
(09:07):
triggered by the coach potentially save them from
conceding and change the course of the match.
That's a huge moment for this kind of officiating technology.
It puts accountability and agency right there on the
touchline. Yeah.
And it's not just staying in youth football, is it?
No, it seems to be gaining traction.
We're already seeing FES being adopted or trialled in other
leagues, like Spain's top women's league League F and
(09:29):
Italy Series C So the institutions, they're clearly
looking for ways to improve accuracy and FES puts a tool
directly in the hands of the teams themselves.
Which brings us perfectly to thecore of our deep dive today.
Because if the institutions are chasing these marginal games, in
fairness, teams themselves, they're locked in this
incredible, almost invisible arms race for hyper specific
(09:51):
systematic gains and human performance.
Physiology, mechanics, recovery,everything.
Exactly. Now we get into the real tech we
need to decode this landscape. We're looking at what around 13
different elite tools that are really defining how athletes are
monitored, trained and managed right now.
OK, let's unpack all of this. Forget the scores.
(10:11):
Forget the ref calls. For a moment.
The real story, the one unfolding every second, is this
torrent of data streaming off the athletes.
That's what's driving performance.
So let's break these tools down by what they do, which we start
maybe the basics, movement tracking.
Yeah, let's start with the foundation.
Locomotion and movement tracking.
(10:31):
This is the GPS backbone of pretty much all modern high
intensity team sports. Hashtag tag tag D1 Locomotion
and movement tracking. The GPS backbone.
OK, first up, probably the name most people might recognize,
Catapult, specifically Catapult 1 is widely used.
If you've seen training footage from, say, a top European club,
you've probably seen players wearing those vests between
(10:51):
their shoulder blade. Right, the little black vest.
Exactly. The key thing about Catapult is
its precision. It's claimed to track up to
12,250 movements per second. Positional accuracy is
apparently within about 100 centimeters, so it gives you
this incredibly detailed pictureof where the player is, how fast
they're moving across like 6 different intensity levels,
(11:12):
everything from walking pace right up to maximum sprints and
sharp changes of direction. But it's not just about how far
they run, is it? I keep hearing about this metric
called player load. Can you break that down for us?
What is player load simply? OK, think of player load as like
a measure of the total mechanical stress on the
athletes body. It's not just distance, it
(11:32):
calculates the cumulative impactfrom all the little
accelerations, decelerations, the changes in direction.
It uses accelerometer data basically.
So it quantifies the instantaneous workload, the
jolt, the impact without just relying on how many kilometers
they covered. It's measuring the physical toll
of stopping, starting, turning sharply.
Right. The stuff that really wears you
down, not just the steady running.
(11:53):
And does focusing on this playerload metric actually lead to
better performance? What is the data show?
Well, the results cited are pretty impressive.
There's data suggesting that after about 3 months of teams
integrating this analysis, players showed on average
something like a 12% increase inthe total distance they could
cover in games, a huge 26% jump in their Sprint distance
(12:14):
capability. And this is crucial, a 3.5%
improvement in their absolute top speed.
Now, 3.5% top speed might not sound like a massive number to
everyone listening, but in football terms that's enormous.
Isn't. It it's absolutely fundamental.
Think about it. A match can hinge on fractions
of a second if a defender can cover that last five or 10
(12:34):
meters to intercept a through ball just 3.5% faster.
That's the difference between cutting out the danger and the
striker being cleaned through ongoal.
It's game changing. And yeah, we know this tech is
deeply embedded in clubs like Real Madrid, Barcelona.
They feed player load data rightinto their whole performance
analysis setup. OK, so that's Catapult.
What else is big in this GPS tracking space?
Another major player is Statsports with their Apex Pro
(12:57):
series. Their angle is slightly
different. They emphasize extremely high
frequency data capture. We're talking an 18 Hertz GPS
system combined with a super fast 952 Hertz accelerometer.
The goal here is absolute data reliability, 0 dropouts, and
getting metrics in real time. So less about one specific
(13:18):
metric like player load, more about the speed and completeness
of the data stream. Kind of, yeah.
They focus heavily on providing live tactical metrics, tracking
about 16 different parameters simultaneously.
Things like total volume speeds in different zones, yes, but
also cardiovascular load indicators.
But the metric or other the outcome they really highlight is
injury prevention. The Holy Grail, particularly
(13:39):
those non contact soft tissue injuries, hamstrings, calves,
groins, the ones that just decimate squads over a long
season. What impact can this kind of
tracking have there? The numbers are pretty
startling, actually. Stat Sports points to a case
study with one major European club client.
They don't name them usually, who reported cutting their soft
tissue injuries literally in half from 44 incidents in one
(14:01):
season down to 22 the next, apparently after fully
integrating the Apex system. Wow cut in half.
That's potentially millions saved in wages for players sat
on the treatment table, not to mention keeping your best
players available for crucial games.
Exactly. It's about performance,
longevity, squad availability, managing resources efficiently.
But let me push back slightly onthat.
(14:22):
How do we know it's just the technology?
Could that club also have changed their training methods,
their physio staff, their schedule?
Is it definitely causation or just correlation?
That's a really fair and important question.
What the performance director isusing systems like Stat Sports
would argue is that the technology enables the better
training decisions. Because they get such granular
(14:44):
real time data on things like Sprint repetition analysis or
high speed running tolerance foreach individual player, they can
see the warning signs before theinjury happens.
OK, so they see player X is hitting their known fatigue
threshold for repeated sprints in this session.
Precisely. And the coach or the sports
scientist on the sideline looking at the live data feed
(15:05):
can say, OK, pull him out now ormodify his next drill.
The tech provides the immediate insight needed to make that
preventative call. So it facilitates the causation
by informing the intervention. That's why you see it used by
giants like Manchester United, Liverpool, PSG.
They need that real time predictive capability.
Hashtag Hashtag D2 bio mechanicsand skill specificity.
(15:28):
What the feet and jumps tell us.OK, so we've covered tracking
the body's general movement around the pitch, but football's
obviously much more specific than that.
What about the actual skills? The kicking, the jumping?
How do we measure the bio mechanics of those actions?
Right, this is where it gets really interesting.
I think we move from tracking the vest on the back to tracking
sensors on the feet themselves. The key player here is the
(15:49):
player Maker Uno foot bounded sensor.
It's actually FIFA approved, which is significant.
It uses these tiny 6 axis smart sensors, accelerometers and
gyroscopes that you strap onto the players boots and these
things are sampling movement data and incredible 7000 times
per second directly from the point of action. 7000 times a
(16:10):
second. OK, so the GPS tells you where
they ran. What does this foot sensor tell
you that the vest can't possiblyknow?
It tells you how they interactedwith the ball on the ground.
It captures really specific technical skill metrics.
Things like their kicking power,the velocity of the ball comes
off their foot, even mapping which part of the foot they used
to make contact. Crucially, it tracks technical
balance, how much they're using their right foot versus their
(16:32):
left for different actions. Wow, imagine being a coach and
getting instant data saying yourwinger completed 80 ercent of
their asses with their right foot in the first half and their
successful dribble rate droed significantly when forced onto
their left. That's incredibly actionable
insight, isn't it? It's potentially revolutionary,
especially for player development, instead of relying
(16:52):
solely on the coach's eye or spending hours manually coding
video footage after the fact. Which is hugely time consuming
and expensive. Exactly.
This system claims to match the accuracy of detailed video
analysis. They cite figures between 95.1%
and 100% accuracy, but delivers the insights almost instantly.
For youth academies, this is gold dust.
(17:14):
You can track the biomechanical load going through each foot,
identifying correct imbalances early and build really
personalized development plans based on objective data,
hopefully preventing chronic injuries caused by those
imbalances later in their career.
OK, so that's the feat. What about the other big
biomechanical stress in football?
Jumping headers, Challenges. Goalkeepers.
(17:35):
There's a lot of explosive vertical movement.
Yep, and that brings us to another specialized piece of
tech, the Vert Jump Monitor. This is basically a small
inertial measurement unit, oftenworn on the waistband, that's
focused entirely on analyzing vertical movement and explosive
power. So it tells you how high someone
jumped. It does, yes.
It calculates vertical displacement jump height,
(17:56):
apparently with around 96% accuracy using something like 53
different calculations simultaneously from its sensors.
But maybe even more importantly than just the height, it
measures the landing force typically expressed in G force.
Landing force. Why is that so critical to
track? Because landing heavily,
repeatedly is a major source of stress on the joints,
particularly knees and ankles, tracking that G force upon
(18:19):
landing gives you a direct measure of the impact stress the
player is absorbing. This data is vital for managing
their overall workload, specifically the acute to
chronic workload ratio. We'll talk more about and
preventing overload injuries from repetitive jumping.
And jumping isn't just an occasional thing in football, is
it? Not at all.
Think about set pieces alone. Corners free kicks analysis
(18:41):
suggests top teams face around 60 set piece situations in a
typical game 6060 Moments where players are potentially jumping
high, challenging aggressively, landing hard.
Being able to monitor the cumulative effect of those
impacts session after session, game after game, and manage that
explosive workload, it becomes absolutely non negotiable for
(19:02):
keeping players fit across a demanding season.
Hashtag tag tag tag D3. Physiological load and recovery.
The body's internal engine. OK, fascinating stuff on the
external movement and the specific skills.
Now let's peel back another layer and go inside the body.
We need to talk about physiological load, how hard the
body's internal engine is working and, critically, how it
(19:22):
recovers. Right.
This is about monitoring the internal response to the
external work. We've just discussed a key
system here is the first Beat Sports Team solution.
They analyze heart rate variability or HRV data
collected from chest straps or integrated vests, but their
specific approach involves usingEPOC models.
EPOC, OK, that's excess post exercise oxygen consumption.
(19:43):
Can you unpack what that actually tells us in simple
terms? Yeah, EPOC is basically a
measure of the increased rate ofoxygen your body consumes after
you've finished exercising. It reflects the energy required
for the body to recover, repair muscle tissue, replenish fuel
stores, get back to its resting state.
So a higher or longer EPOC response generally indicates a
(20:04):
more intense or strenuous workout that requires more
recovery. First Beat uses this to model
the intensity of the exercise session very precisely.
And the ultimate goal of modeling intensity this way is
to manage something crucial you mentioned earlier, the acute to
chronic load ratio or ACLR. We need to make this clear for
everyone listening. What is ACLR and why is it so
(20:25):
important? OK, think of it like this.
The acute load is the stress or workload your body has
experienced very recently, say over the last seven days.
The chronic load is your baseline fitness, the workload
your body has become accustomed to over a longer period, maybe
the last 28 days. The ACLR is the ratio between
those two. So it's comparing the sudden
recent strain against your established fitness level.
(20:46):
Exactly. If your acute load suddenly
spikes way above your chronic load, meaning you've done a lot
more intense work recently than your body is used to, you're
fatigued, you're potentially under recovered, and your risk
of injury shoots up. Conversely, if your acute load
drops too low compared to your chronic load, you might actually
be detraining losing fitness. So there's a sweet spot kind of
(21:09):
Goldilocks zone for this ratio. That's the idea.
Sports scientists generally aim to keep the ACLR somewhere
between .8 and 1.3. Below .8, you risk detraining.
Above 1.3, maybe even 1.5 depending on the model, the
injury risk increases significantly.
First Beat system is designed tohelp teams monitor this
constantly and keep players within that optimal training
(21:31):
zone. And is this theoretical optimal
zone translate into real world results?
Well, there's a compelling case study often cited involving
Juventus FC. Apparently, after a bit of a
shaky start to their 2020-2021 Champions League campaign, they
really doubled down on using this kind of physiological
monitoring to optimize player load and recovery.
And what happened? Subsequently, later in that same
(21:52):
campaign, they went to camp New and beat Barcelona 3 nil.
Cintus became the first Italian team ever to score three goals
against Barcelona at their home ground in a UEFA competition.
Now, you can't attribute that solely to the tech, of course,
but it strongly suggests that getting the physiological
management right, keeping players fresh and resilient
using data like EPOC and ACLR, directly contributes to
(22:14):
performing at the absolute peak under immense pressure.
Interesting. OK, so first beat focuses on
EPOC and ACLR. What other systems are crucial
for monitoring that internal engine?
Another well established player is the Polar Team Pro system.
They also use chest straps or integrated sensors, focusing on
very accurate heart rate monitoring and cardiovascular
(22:35):
load tracking. Their sensors are tiny, just 38
grams. They capture maximum heart
rates, which in elite football training often fall in the 165
to 188 beats per minute range. And what's polar specific
strength and analysis. They excel at what's called
training intensity distribution analysis.
So breaking down a whole training session or even a
week's worth of training by how much time players spent in
(22:57):
different heart rate zones. Low intensity, Moderate
intensity. High intensity.
Maximum intensity. Why is that distribution useful
for a coach? Because it allows them them to
objectively verify if the session they designed actually
delivered the intended physiological stimulus.
For example, studies using Polarfound players might spend around
76% of their time in low intensity zones, maybe only 6%
(23:21):
in the middle zones, but a significant 18% in high
intensity zones if a coach planned a high intensity
session. But the data shows players
barely touch those top zones. They know they need to adjust
the drills next time, or vice versa.
If it was meant to be a recoverysession but players spent too
long at high intensity, that's ared flag.
And they get this feedback quickly.
(23:41):
Yeah, that's key. The Polar system provides real
time feedback directly to an iPad on the sideline.
Coaches can monitor up to 60 players simultaneously within a
range of about 200 meters, so they can see instantly if the
team's overall intensity is dropping or if specific
individuals are working too hardor not hard enough, and make
adjustments right there and then.
Real time control. One more in this physiological
(24:03):
section. Yes, and this one is really
pushing the boundaries. It's the Moxie Muscle Oxygen
Monitor. This moves beyond just heart
rate and looks directly at what's happening inside the
muscle tissue itself. It uses near infrared
spectroscopy and IRS technology to measure muscle oxygen
saturation or SMO 2 non invasively and in real time.
OK, NIRSSM O2. That's simplifying heart rate,
(24:26):
tells you how hard the heart is pumping blood.
What does muscle oxygen saturation tell you that's
different? SMO 2 tells you how efficiently
the muscles are actually using the oxygen being delivered by
that blood. It's a direct indicator of the
balance between oxygen supply and oxygen demand within the
working muscle, so it gives you insights into metabolic
efficiency, how well the muscle is generating energy.
(24:47):
And how does a coach use that information?
It allows them to pinpoint very precise physiological thresholds
and training zones for individual athletes.
For example, they can identify the fat Max zone, the intensity
level at which the body maximizes its rate of fat
oxidation for fuel. Why is knowing the Fat Max zone
so valuable? Because training strategically
within or around that zone can improve the body's ability to
(25:10):
burn fat as fuel, which helps spare precious glycogen stores
during long matches. Moxie suggests this zone often
occurs when SMO 2 is at or belowabout 37%.
Having that precise real time SMO two data allows coaches to
prescribe training intensities with incredible accuracy,
ensuring players are getting theright metabolic stimulus to
(25:30):
improve endurance without, you know, completely emptying their
energy tanks unnecessarily. It correlates strongly with
other measures like VO2 Max, butgives a localized muscle
specific picture. Hashtag tag tag D4 now.
Wellness environment and optimization.
Managing the human element. OK.
We've covered movement skills, internal load during exercise,
but performance isn't just aboutwhat happens during training or
(25:53):
games, right? It's a 247 process, managing
recovery, sleep, overall Wellness, even the environment
that's become just as critical. Absolutely.
The modern elite athlete is viewed as a holistic system.
What happens off the pitch is arguably as important as what
happens on it, and this is wherewearable Wellness and recovery
(26:14):
technology has exploded. The two big players everyone
talks about are the W-84 Point Orecovery wristband and the RO
Ring Gen. 3. Right, you see athletes across
all sports wearing these. Now let's start with W app.
Their big focus seems to be sleep, doesn't it?
Yeah, sleep is fundamental to their platform.
The W8 band tracks your sleep stages, slow wave sleep, REM
(26:34):
sleep, light sleep and periods of wakefulness throughout the
night. And they claim the accuracy
rivals laboratory based polysomography, which is the
gold standard for sleep tracking.
And what does it do with all that sleep data?
It synthesizes it along with other metrics like resting heart
rate, heart rate variability, HRV, and respiratory rate into a
single, easy to understand dailyrecovery score.
(26:57):
This score is usually presented with the color code.
Green means you're well recovered and ready for high
strain. Yellow suggests you're OK but
maybe need to moderate intensity.
Red indicates you're fatigued orunder recovered and should
prioritize rest or active recovery.
So it's basically giving the player and the coach a daily
readiness signal. Exactly.
It takes the guesswork out of How do I feel today Arsenal FC
(27:20):
is 1 prominent football club known to use loop extensively
with their players to guide training load decisions based on
objective recovery data. OK, And the aura ring often seen
on the fingers of players, including reportedly at Real
Madrid. How does it differ?
Similar goal, different approach.
Similar goal, optimizing readiness and recovery, but it
leverages slightly different data points collected from the
(27:41):
finger, which is apparently verygood for accurate signal
capture. Aura puts a huge emphasis on
heart rate variability, or HRV. We mentioned HRV with first beat
2. Remind us why HRV is such a key
indicator? HRV is the tiny variation in the
time interval between consecutive heartbeats.
A higher HRV generally indicatesbetter recovery, lower stress,
(28:02):
and a well functioning autonomicnervous system that's ready to
adapt. Aura claims their ring measures
HRV with 98.4% accuracy comparedto a medical grade
electrocardiogram ECG that's incredibly precise for a
consumer wearable. Wow, ECG level accuracy from a
ring. Apparently so.
And like WATR combines HRV with sleep stage analysis, resting
(28:24):
heart rate, and, importantly, body temperature variation to
calculate its own daily readiness score.
It's looking for stability and positive trends in these key
biometric markers. So coaches are getting these
highly accurate, deeply personalbiometric scores every single
day. It allows for incredibly
personalized training adjustments.
But this must raise some questions, right?
We're talking about really intimate data here.
(28:45):
It absolutely does and it's a growing point of discussion and
sometimes tension within professional sports.
You touched on earlier. Studies show a large majority,
something like 78%, of professional footballers have
concerns about how their biometric data might be used or
potentially misused. Yeah, you can imagine, right?
What if your contract negotiation hinges on your
average recovery score? Or what if you feel absolutely
(29:07):
fine mentally ready to play, butyour wearable says you're in the
red zone and the coach benches you based on that data alone?
Exactly. There's a real ethical pipe rope
to walk here between optimizing performance for the team and
respecting player autonomy and privacy.
It highlights why Robust data security protocols, clear
agreements on data ownership andusage, which companies like W
(29:29):
APE and Aura do emphasize, are absolutely crucial as this
technology becomes more embedded.
OK, besides sleep in general recovery, what about specific
environmental factors? Heat, for instance.
Football's played all over the world, often in really
challenging climates. Yeah, managing heat stress is
critical, and for that we have technology like the core body
temperature sensor. This is a wearable sensor, often
(29:51):
worn on a chest strap or stuck to the body, that measures core
body temperature continuously and noninvasively.
Noninvasively so. No need for those ingestible
pills anymore. Exactly.
It provides real time accurate core temp readings and it
calculates something called a heat strain index, typically on
a scale of zero to 10, to quantify the level of heat
(30:13):
stress the athlete is under. This tech was apparently used
quite a bit during the 2022 World Cup in Qatar, where
managing heat, even with stadiumcooling was a major concern.
Temperatures were still around 2126°C.
And the impact of unmanaged heaton performance is massive,
isn't? It it's huge.
Research shows that athletes whocan't effectively manage heat
accumulation can see their performance capability drop by
(30:36):
as much as 26%. That's devastating in a sport
decided by fine margins. But the flip side is also true
if you manage it well. Exactly.
If you use data from sensors like CORD to guide heat
acclimatization protocols and manage intensity during hot
conditions, you can actually boost performance.
Studies show proper heat acclimatization can improve time
(30:56):
trial performance by around 8%. Knowing precisely when an
athlete score temperature is nearing a critical threshold
allows coaches or medical staff to intervene, adjust pacing,
ensure cooling strategies, modify hydration before
performance plummets or worse, heat illness occurs.
And hydration goes hand in hand with heat management.
(31:16):
Any breakthroughs there? Yes, this is another really
exciting area. Nick's biosensors have developed
a wearable patch that monitors hydration status in real time by
actually analyzing the composition of an athlete's
sweat. Analyzing sweat, How does that
work? The patch sticks to the skin,
collects a tiny amount of sweat,and analyzes it on the spot.
It calculates the person's real time whole body sweat rate, how
(31:39):
much fluid they're losing per hour, and crucially, it also
measures the sodium concentration in their sweat.
Why is sodium concentration so important?
Doesn't everyone just need electrolytes?
They do, but the amount varies hugely between individuals.
Some athletes are salty sweatersand lose a lot of sodium, maybe
up to 2000 milligrams per liter of sweat, while others lose much
(31:59):
less, maybe only 200 milligl. If you don't replace sodium
adequately, performance suffers.Cramping risk increases.
NICs provides personalized alerts based on the individual
sweat rate and sodium loss, telling them exactly how much
fluid and how much sodium they need to replenish.
So no more generic drink X amount of sports drink advice.
(32:20):
This is truly personalized hydration strategy.
Precisely. It takes the desk workout.
It's particularly valuable for workouts or matches lasting
longer than, say, 45 minutes, especially in the heat, where
athletes can easily sweat more than a liter per hour.
It ensures they replace exactly what they're losing.
Hashtag tag Tag D5. The frontier of training.
Neurostimulation. OK, we've tracked movement
(32:42):
skills, internal Physiology, recovery environment.
Feels like we've covered the body from every angle.
But there's one more frontier, isn't there?
Something that goes beyond just monitoring or managing the body.
Something that tries to activelyenhance the brain's ability to
learn. Yeah, now we're really getting
into the cutting edge. We're talking about
neurostimulation, specifically using technology like the Halo
(33:02):
Sport 2 Neurostimulation headset.
Neurostimulation headset. It sounds like something out of
science fiction. What does it actually do?
It uses a technique called transcranial direct current
stimulation, or TDCS. Basically, the headset has
primals that sit on the scalp over the motor cortex, the part
of the brain that controls movement.
It delivers a very weak, safe electrical current, usually up
(33:24):
to about two milliamps to that specific brain region.
OK. Why would you want to send
electrical currents into your brain before you train?
What's the goal? The goal is to temporarily
increase neuroplasticity in the motor cortex.
Think of plasticity as the brains ability to change, adapt
and learn new skills by forming and strengthening neural
connections. The TDCS from Halo Sport is
(33:47):
designed to put the motor cortexinto a state of hyperplasticity,
or heightened readiness to learnfor a short period.
So it's like warming up the brain circuits responsible for
movement skills. That's a good analogy.
It makes those neurons more excitable, more receptive to
forming the connections needed to master a physical skill.
So when the athlete then goes and practices that skill,
(34:08):
whether it's perfecting a golf swing, learning a complex
gymnastic routine, or refining their penalty kick technique in
football, the theory is that thebrain learns faster, the muscle
memory forms more efficiently, and the skill improvement is
accelerated because the underlying neural pathways are
being strengthened more effectively during that primed
(34:28):
window. And is there evidence this
actually works? Does zapping your brain make you
better at sports? Well, the company points to
clinical studies, some independent, some internal.
One often cited study involved amotor learning task like dart
throwing, where participants using the TDCS before practice
showed significantly faster improvement rates, sometimes
quoted as high as 50% faster learning compared to a control
(34:52):
group doing the same practice without stimulation. 50% faster
learning. That's potentially huge.
How do athletes typically use it?
The standard protocol is a 20 minute neural priming session
wearing the headset immediately before a training session
focused on skill development or intense physical output.
This hyperplasticity effect is thought to last for about an
(35:12):
hour afterwards, so they aim to maximize that window for high
quality practice. This feels like a real paradigm
shift doesn't it? Moving from just measuring and
managing the athletes current state to actively intervening to
accelerate their potential. It really does.
It's moving from observation andoptimization to active
enhancement. And that's why you see this kind
of technology TDCS being explored and adopted not just in
(35:36):
niche sports, but across major leagues like the NFLNBAMLB and
in elite military training, too.They're constantly looking for
that next edge, and priming the brain itself is, well, pretty
compelling Frontier. So yeah, when you sit back and
look at it all, we've gone from the raw, visceral emotion of a
youth tournament elimination decided by a single goal
(35:57):
different statistic, all the waydown to devices monitoring the
oxygen levels and individual muscle fibers in real time, and
even headsets aiming to boost the brains learning speed with
electrical currents. The key take away is the
synthesis. It's not about any single
gadget, is it? Not at all.
The truly successful teams, the ones consistently performing at
the elite level, whether it's developing young talent OR
(36:17):
competing for Champions League titles, they aren't just relying
on one piece of tech, they're building this comprehensive,
interconnected ecosystem. They're layering GPS data with
biomechanical insights from footsensors, overlaying that with
internal physiological load fromheart rate and SMO 2 monitors,
and managing it all based on recovery scores from sleep
trackers and readiness data. They're building these
(36:40):
incredibly detailed, dynamic, almost predictive profiles of
every single athlete. The era of relying purely on
coach's intuition or generic training plans that's well and
truly over at the top level isn't.
It it absolutely is. The data confirms the shift
every single aspect of preparingan athlete, from designing
training drills, to managing injury risk using things like
(37:02):
ECLR, to ensuring they peek perfectly for that one crucial
knockout match using readiness squares, it's all now
fundamentally intertwined with sports science and technology.
It has become a data-driven endeavor through and through.
And the performance gains, thesetools on lock are undeniable.
They're transforming what athletes are capable of.
But as we've touched on, this technological revolution forces
(37:25):
us to confront a really significant and frankly quite
challenging reality that's only going to become more prominent.
All this technology we spent thelast while unpacking it,
generates vast quantities of incredibly sensitive personal
biometric data about the players.
Their sleep patterns, their hearts response to stress, their
muscle efficiency, maybe even predispositions to certain
(37:45):
injuries based on bio mechanics or genetics, potentially even
how their brain responds to learning stimuli.
It's deeply personal stuff. And that leads us to the final
really provocative question we wanted to leave you at the
listener thinking about today asthis kind of performance
technology becomes not just advantageous, but potentially
mandatory for competing at the highest level.
(38:05):
As players increasingly become walking, talking constant
streams of biometric data, how do we as a sporting community,
as a society, fundamentally manage player privacy and data
ownership in the future of elitesports?
How do we ensure we protect the human being at the center of all
these sensors?
Forget the scoreboard for a second.
Forget who lifted the trophy. Look closer.
Look at the invisible river of data flowing off every single
player. That right there, that's the
real pulse of elite competition today.
Welcome to the deep dive. We're not here just to rehash
results. No, we're plugging in.
We're strapping on the sensors, and we're zooming right into the
heart of the beautiful game. We're here to dissect the
(00:23):
incredible. Almost surgical way data science
is rewriting the rules of human performance.
It's not just skill anymore, is it?
It's muscle, it's metabolism, and it's machine learning all
rolled into one. Absolutely.
It's the ultimate blend of competition and code, really.
And we're using a recent major global youth tournament as our
backdrop. You know, these events are
(00:44):
intense pressure cookers. The margins between winning and
going home, they're unbelievablythin.
Razor thin. And now those margins aren't
just moments of brilliance. They're measured in
milliseconds, in tiny variationsand physiological readings.
So our mission today is to get past the headlines, past the
final scores and really understand the the complex
tools, the integrated systems that are basically defining
(01:06):
success at this top level. Now we're going right to the
performance lab, so to speak, todecode this fusion of, well, raw
talent and super specific analytics.
Exactly. And just to paint the picture,
you have to appreciate how incredibly tight this
environment is. When you have teams this evenly
matched in terms of raw talent, success often just boils down to
(01:28):
1 tiny edge in preparation, or maybe even a single decimal
point in some complex tiebreakerrule.
Oh, the tiebreakers. You really feel the the sting of
it when you see a team's entire tournament decided not just by
wins or losses, but by these really quite intricate rules
around goal difference. We saw that play out, didn't we,
with Egypt's U20 team? Yeah, it was tough to watch.
They fought incredibly hard. They even pulled off a really
(01:50):
spirited 2 one win against Chile, the hosts in their last
group game that gave them three points, but that was it for
them. Their journey ended right there.
The sheer complexity of the group stage tiebreakers, that
was their undoing. It's the fine print that gets
you, isn't it? They ended up with a goal
difference of -2 OK, and they'd scored three goals across their
matches and that, that single detail was everything.
(02:13):
They were out ranked sixth amongall the 3rd place teams.
And why? Because Australia, who also had
a -2 goal difference, had managed to score four goals,
just one more goal than Egypt. One goal.
That's the difference between advancing and booking flights
home. It just hammers home that at
this level, your preparation, your execution, it has to be
almost perfect. It really does.
(02:34):
And, you know, that was Egypt's fourth early exit at this stage
in this specific tournament series, going back to 91 one,
2005, 2013. It shows how hard it is to
consistently breakthrough. Their best finish, remember, was
third place way back in 2001. Those tiny margins, they can be
brutal. But it wasn't all heartbreak for
African teams, it actually showed the strength building in
their youth programs right now. We saw Morocco, South Africa and
(02:57):
Nigeria all make it through to the knockout rounds. 3 teams in
the round of 16. That's a strong showing.
Definitely. And they faced some really tough
matchups too. Morocco drew South Korea,
Nigeria had this huge rematch against Argentina.
You might remember Nigeria actually beat them two nil in a
previous quarterfinal. So there was history there.
Right. And South Africa, they really
showed what they were made of inthe group stage.
(03:19):
They got through too. Now, there was a little bit of
confusion in the reports about exactly who they played next.
Some said Columbia, others Norway, but honestly the key
thing is how they got there. Their performance in Group E was
well it was a master class in resilience and navigating those
tricky tiebreaker situations. Oh, absolutely.
South Africa pulled off a brilliant 21 comeback victory
(03:41):
against the United States. They actually went down one nil
early on. Noah Cobb scored for the US, but
South Africa, they just didn't buckle.
No, they hit back pretty quickly.
Their pressure forced an own goal from the US defender Joshua
Weinter that level things up. And then just before halftime,
Golmawa Kakana finished it off, converting a really smart
(04:01):
cutback. That fightback really summed up
their group stage. But here's the really
fascinating part, the bit that shows how complex modern
tournament football is. Even though the US lost that
game to South Africa, the US still ended up winning Group E
South Africa finished second. How?
Because of the tiebreakers again.
Earlier in the group, the US hadpulled off a massive 3 nil upset
(04:24):
against France. Goals from Xavier Gozo, Brooklyn
Reigns, Marco Zambrano, Delgado That big win, that goal
difference boost against France was ultimately what separated
them when all the head to head calculations were done between
the Tide teams. It's mind bending, isn't it?
It really is. And that whole Group E
situation, it perfectly capturesour theme today, doesn't it?
(04:44):
The tiny difference between going home early like Egypt, or
winning the group like the US. It can come down to a single
performance against a totally different team earlier on.
All filter through layers of statistical rules.
It just shows that success now isn't just about coaching
skills. It demands institutional
brainpower and analytical innovation too.
That's a perfect transition. Let's shift gears now from the
(05:07):
drama playing out on the pitch itself and look at the sort of
the institutional framework thatunderpins elite football today.
The watchers and the rules, as you put it.
These big tournaments, they aren't just talent showcases
anymore. They're active labs for trying
out new ideas, both in how teamstrain and how the game is
officiated. OK, first up, let's talk about
the intelligence unit, if you will, the technical study group,
(05:31):
the TSG. So if the teams are using data
to get better, the TSG is using data to what?
Make coaching better globally. What's their actual mission?
It's pretty comprehensive actually.
The TS GS job is to deliver really cutting edge, systematic
analysis of every single match in the tournament, all 52 of
them. They're looking for tactical
trends, new formations, any kindof unique innovation.
(05:52):
Teams are trying and importantly, they're the ones
who select the individual award winner, like the Golden Ball for
the best player. It's not just casual
observation, it's high level football, intelligence gathering
and synthesis. And the people involved tell you
everything about how seriously this is taken.
It's led by Pascal Zuberviller, FIFA's senior football expert.
Former Swiss international goalkeeper right famously didn't
(06:14):
concede a single goal in open play during the entire 2006
world. Cup, that's the one.
Pretty good credentials for analyzing defense and game
management. You'd think so.
And he's joined by really interesting mix of expertise.
You've got Corinne Dyecker, former French defender, then
manager, notably the first womanto manage a men's professional
team in France's league, too. Huge experience there.
(06:37):
Wow. OK.
Then there's Marcin Dorna, who'sa Polish specialist really
focused on youth development systems, and Marcelo Jarrah, a
former Chilean forward who's gone into high level coaching.
So you get this great blend of perspectives.
Goalkeeping, management, tactics, youth development,
Attacking play, they're coveringall the angles and this
knowledge doesn't just stay within FIFA, does it?
No, that's key. The insights they gather, the
(06:59):
trends they identify, it's all shared globally through the FIFA
Training Center platform. The idea is to sort of
democratize that cutting edge knowledge, help coaches
everywhere understand what elitesuccess looks like right now.
So this drive for kind of intellectual games, for smarter
football, it's mirrored by a similar push for games in
(07:20):
fairness and accuracy on the pitch itself.
We saw this tournament used as atesting ground for a new
officiating system, right? Football video support or FES?
That's right, FES. It's essentially an alternative
to the standard VAR system we'reused to seeing.
It was trialled here specifically to look at those
big match changing moments, potential clear and obvious
errors related to goals, penalties, direct red cards or
(07:42):
cases of mistaken identity. But the really interesting twist
is how it involves the coaches. Yeah, this part is fascinating.
It gives the power back to the benches in a way.
It completely changes the dynamic.
Instead of waiting for the VAR officials to initiate a review,
FBS gives each team's coach 2 challenges per match.
They signal their challenge using a designated blue or maybe
(08:04):
purple card to appeal a specificrefereeing decision.
And here's the clever bit. If their challenge is
successful, meaning the video review actually overturns the
referee's original call, they get to keep that challenge.
They don't lose it. Exactly.
But if the review confirms the ref's decision if the coach was
wrong, then they lose one of their two challenges for the
(08:25):
rest of the match. So it becomes this high stakes
tactical decision for the coach,doesn't it?
Is this call important enough torisk using a challenge I might
desperately need later in the game?
Precisely. And we saw it used effectively
almost straight away. Yeah, tell us about that first
successful challenge. It happened in Morocco's two nil
victory over Spain. The Moroccan coach Muhammad Wabi
(08:45):
used his challenge card, his blue card in this case, to
contest a penalty that had just been awarded against his team.
Very the referee went to the monitor, reviewed the incident
based on the coaches challenge and ultimately agreed.
The penalty decision was overturned and because Morocco's
challenge was successful, they kept their full quota of
challenges. That single intervention
(09:07):
triggered by the coach potentially save them from
conceding and change the course of the match.
That's a huge moment for this kind of officiating technology.
It puts accountability and agency right there on the
touchline. Yeah.
And it's not just staying in youth football, is it?
No, it seems to be gaining traction.
We're already seeing FES being adopted or trialled in other
leagues, like Spain's top women's league League F and
(09:29):
Italy Series C So the institutions, they're clearly
looking for ways to improve accuracy and FES puts a tool
directly in the hands of the teams themselves.
Which brings us perfectly to thecore of our deep dive today.
Because if the institutions are chasing these marginal games, in
fairness, teams themselves, they're locked in this
incredible, almost invisible arms race for hyper specific
(09:51):
systematic gains and human performance.
Physiology, mechanics, recovery,everything.
Exactly. Now we get into the real tech we
need to decode this landscape. We're looking at what around 13
different elite tools that are really defining how athletes are
monitored, trained and managed right now.
OK, let's unpack all of this. Forget the scores.
(10:11):
Forget the ref calls. For a moment.
The real story, the one unfolding every second, is this
torrent of data streaming off the athletes.
That's what's driving performance.
So let's break these tools down by what they do, which we start
maybe the basics, movement tracking.
Yeah, let's start with the foundation.
Locomotion and movement tracking.
(10:31):
This is the GPS backbone of pretty much all modern high
intensity team sports. Hashtag tag tag D1 Locomotion
and movement tracking. The GPS backbone.
OK, first up, probably the name most people might recognize,
Catapult, specifically Catapult 1 is widely used.
If you've seen training footage from, say, a top European club,
you've probably seen players wearing those vests between
(10:51):
their shoulder blade. Right, the little black vest.
Exactly. The key thing about Catapult is
its precision. It's claimed to track up to
12,250 movements per second. Positional accuracy is
apparently within about 100 centimeters, so it gives you
this incredibly detailed pictureof where the player is, how fast
they're moving across like 6 different intensity levels,
(11:12):
everything from walking pace right up to maximum sprints and
sharp changes of direction. But it's not just about how far
they run, is it? I keep hearing about this metric
called player load. Can you break that down for us?
What is player load simply? OK, think of player load as like
a measure of the total mechanical stress on the
athletes body. It's not just distance, it
(11:32):
calculates the cumulative impactfrom all the little
accelerations, decelerations, the changes in direction.
It uses accelerometer data basically.
So it quantifies the instantaneous workload, the
jolt, the impact without just relying on how many kilometers
they covered. It's measuring the physical toll
of stopping, starting, turning sharply.
Right. The stuff that really wears you
down, not just the steady running.
(11:53):
And does focusing on this playerload metric actually lead to
better performance? What is the data show?
Well, the results cited are pretty impressive.
There's data suggesting that after about 3 months of teams
integrating this analysis, players showed on average
something like a 12% increase inthe total distance they could
cover in games, a huge 26% jump in their Sprint distance
(12:14):
capability. And this is crucial, a 3.5%
improvement in their absolute top speed.
Now, 3.5% top speed might not sound like a massive number to
everyone listening, but in football terms that's enormous.
Isn't. It it's absolutely fundamental.
Think about it. A match can hinge on fractions
of a second if a defender can cover that last five or 10
(12:34):
meters to intercept a through ball just 3.5% faster.
That's the difference between cutting out the danger and the
striker being cleaned through ongoal.
It's game changing. And yeah, we know this tech is
deeply embedded in clubs like Real Madrid, Barcelona.
They feed player load data rightinto their whole performance
analysis setup. OK, so that's Catapult.
What else is big in this GPS tracking space?
Another major player is Statsports with their Apex Pro
(12:57):
series. Their angle is slightly
different. They emphasize extremely high
frequency data capture. We're talking an 18 Hertz GPS
system combined with a super fast 952 Hertz accelerometer.
The goal here is absolute data reliability, 0 dropouts, and
getting metrics in real time. So less about one specific
(13:18):
metric like player load, more about the speed and completeness
of the data stream. Kind of, yeah.
They focus heavily on providing live tactical metrics, tracking
about 16 different parameters simultaneously.
Things like total volume speeds in different zones, yes, but
also cardiovascular load indicators.
But the metric or other the outcome they really highlight is
injury prevention. The Holy Grail, particularly
(13:39):
those non contact soft tissue injuries, hamstrings, calves,
groins, the ones that just decimate squads over a long
season. What impact can this kind of
tracking have there? The numbers are pretty
startling, actually. Stat Sports points to a case
study with one major European club client.
They don't name them usually, who reported cutting their soft
tissue injuries literally in half from 44 incidents in one
(14:01):
season down to 22 the next, apparently after fully
integrating the Apex system. Wow cut in half.
That's potentially millions saved in wages for players sat
on the treatment table, not to mention keeping your best
players available for crucial games.
Exactly. It's about performance,
longevity, squad availability, managing resources efficiently.
But let me push back slightly onthat.
(14:22):
How do we know it's just the technology?
Could that club also have changed their training methods,
their physio staff, their schedule?
Is it definitely causation or just correlation?
That's a really fair and important question.
What the performance director isusing systems like Stat Sports
would argue is that the technology enables the better
training decisions. Because they get such granular
(14:44):
real time data on things like Sprint repetition analysis or
high speed running tolerance foreach individual player, they can
see the warning signs before theinjury happens.
OK, so they see player X is hitting their known fatigue
threshold for repeated sprints in this session.
Precisely. And the coach or the sports
scientist on the sideline looking at the live data feed
(15:05):
can say, OK, pull him out now ormodify his next drill.
The tech provides the immediate insight needed to make that
preventative call. So it facilitates the causation
by informing the intervention. That's why you see it used by
giants like Manchester United, Liverpool, PSG.
They need that real time predictive capability.
Hashtag Hashtag D2 bio mechanicsand skill specificity.
(15:28):
What the feet and jumps tell us.OK, so we've covered tracking
the body's general movement around the pitch, but football's
obviously much more specific than that.
What about the actual skills? The kicking, the jumping?
How do we measure the bio mechanics of those actions?
Right, this is where it gets really interesting.
I think we move from tracking the vest on the back to tracking
sensors on the feet themselves. The key player here is the
(15:49):
player Maker Uno foot bounded sensor.
It's actually FIFA approved, which is significant.
It uses these tiny 6 axis smart sensors, accelerometers and
gyroscopes that you strap onto the players boots and these
things are sampling movement data and incredible 7000 times
per second directly from the point of action. 7000 times a
(16:10):
second. OK, so the GPS tells you where
they ran. What does this foot sensor tell
you that the vest can't possiblyknow?
It tells you how they interactedwith the ball on the ground.
It captures really specific technical skill metrics.
Things like their kicking power,the velocity of the ball comes
off their foot, even mapping which part of the foot they used
to make contact. Crucially, it tracks technical
balance, how much they're using their right foot versus their
(16:32):
left for different actions. Wow, imagine being a coach and
getting instant data saying yourwinger completed 80 ercent of
their asses with their right foot in the first half and their
successful dribble rate droed significantly when forced onto
their left. That's incredibly actionable
insight, isn't it? It's potentially revolutionary,
especially for player development, instead of relying
(16:52):
solely on the coach's eye or spending hours manually coding
video footage after the fact. Which is hugely time consuming
and expensive. Exactly.
This system claims to match the accuracy of detailed video
analysis. They cite figures between 95.1%
and 100% accuracy, but delivers the insights almost instantly.
For youth academies, this is gold dust.
(17:14):
You can track the biomechanical load going through each foot,
identifying correct imbalances early and build really
personalized development plans based on objective data,
hopefully preventing chronic injuries caused by those
imbalances later in their career.
OK, so that's the feat. What about the other big
biomechanical stress in football?
Jumping headers, Challenges. Goalkeepers.
(17:35):
There's a lot of explosive vertical movement.
Yep, and that brings us to another specialized piece of
tech, the Vert Jump Monitor. This is basically a small
inertial measurement unit, oftenworn on the waistband, that's
focused entirely on analyzing vertical movement and explosive
power. So it tells you how high someone
jumped. It does, yes.
It calculates vertical displacement jump height,
(17:56):
apparently with around 96% accuracy using something like 53
different calculations simultaneously from its sensors.
But maybe even more importantly than just the height, it
measures the landing force typically expressed in G force.
Landing force. Why is that so critical to
track? Because landing heavily,
repeatedly is a major source of stress on the joints,
particularly knees and ankles, tracking that G force upon
(18:19):
landing gives you a direct measure of the impact stress the
player is absorbing. This data is vital for managing
their overall workload, specifically the acute to
chronic workload ratio. We'll talk more about and
preventing overload injuries from repetitive jumping.
And jumping isn't just an occasional thing in football, is
it? Not at all.
Think about set pieces alone. Corners free kicks analysis
(18:41):
suggests top teams face around 60 set piece situations in a
typical game 6060 Moments where players are potentially jumping
high, challenging aggressively, landing hard.
Being able to monitor the cumulative effect of those
impacts session after session, game after game, and manage that
explosive workload, it becomes absolutely non negotiable for
(19:02):
keeping players fit across a demanding season.
Hashtag tag tag tag D3. Physiological load and recovery.
The body's internal engine. OK, fascinating stuff on the
external movement and the specific skills.
Now let's peel back another layer and go inside the body.
We need to talk about physiological load, how hard the
body's internal engine is working and, critically, how it
(19:22):
recovers. Right.
This is about monitoring the internal response to the
external work. We've just discussed a key
system here is the first Beat Sports Team solution.
They analyze heart rate variability or HRV data
collected from chest straps or integrated vests, but their
specific approach involves usingEPOC models.
EPOC, OK, that's excess post exercise oxygen consumption.
(19:43):
Can you unpack what that actually tells us in simple
terms? Yeah, EPOC is basically a
measure of the increased rate ofoxygen your body consumes after
you've finished exercising. It reflects the energy required
for the body to recover, repair muscle tissue, replenish fuel
stores, get back to its resting state.
So a higher or longer EPOC response generally indicates a
(20:04):
more intense or strenuous workout that requires more
recovery. First Beat uses this to model
the intensity of the exercise session very precisely.
And the ultimate goal of modeling intensity this way is
to manage something crucial you mentioned earlier, the acute to
chronic load ratio or ACLR. We need to make this clear for
everyone listening. What is ACLR and why is it so
(20:25):
important? OK, think of it like this.
The acute load is the stress or workload your body has
experienced very recently, say over the last seven days.
The chronic load is your baseline fitness, the workload
your body has become accustomed to over a longer period, maybe
the last 28 days. The ACLR is the ratio between
those two. So it's comparing the sudden
recent strain against your established fitness level.
(20:46):
Exactly. If your acute load suddenly
spikes way above your chronic load, meaning you've done a lot
more intense work recently than your body is used to, you're
fatigued, you're potentially under recovered, and your risk
of injury shoots up. Conversely, if your acute load
drops too low compared to your chronic load, you might actually
be detraining losing fitness. So there's a sweet spot kind of
(21:09):
Goldilocks zone for this ratio. That's the idea.
Sports scientists generally aim to keep the ACLR somewhere
between .8 and 1.3. Below .8, you risk detraining.
Above 1.3, maybe even 1.5 depending on the model, the
injury risk increases significantly.
First Beat system is designed tohelp teams monitor this
constantly and keep players within that optimal training
(21:31):
zone. And is this theoretical optimal
zone translate into real world results?
Well, there's a compelling case study often cited involving
Juventus FC. Apparently, after a bit of a
shaky start to their 2020-2021 Champions League campaign, they
really doubled down on using this kind of physiological
monitoring to optimize player load and recovery.
And what happened? Subsequently, later in that same
(21:52):
campaign, they went to camp New and beat Barcelona 3 nil.
Cintus became the first Italian team ever to score three goals
against Barcelona at their home ground in a UEFA competition.
Now, you can't attribute that solely to the tech, of course,
but it strongly suggests that getting the physiological
management right, keeping players fresh and resilient
using data like EPOC and ACLR, directly contributes to
(22:14):
performing at the absolute peak under immense pressure.
Interesting. OK, so first beat focuses on
EPOC and ACLR. What other systems are crucial
for monitoring that internal engine?
Another well established player is the Polar Team Pro system.
They also use chest straps or integrated sensors, focusing on
very accurate heart rate monitoring and cardiovascular
(22:35):
load tracking. Their sensors are tiny, just 38
grams. They capture maximum heart
rates, which in elite football training often fall in the 165
to 188 beats per minute range. And what's polar specific
strength and analysis. They excel at what's called
training intensity distribution analysis.
So breaking down a whole training session or even a
week's worth of training by how much time players spent in
(22:57):
different heart rate zones. Low intensity, Moderate
intensity. High intensity.
Maximum intensity. Why is that distribution useful
for a coach? Because it allows them them to
objectively verify if the session they designed actually
delivered the intended physiological stimulus.
For example, studies using Polarfound players might spend around
76% of their time in low intensity zones, maybe only 6%
(23:21):
in the middle zones, but a significant 18% in high
intensity zones if a coach planned a high intensity
session. But the data shows players
barely touch those top zones. They know they need to adjust
the drills next time, or vice versa.
If it was meant to be a recoverysession but players spent too
long at high intensity, that's ared flag.
And they get this feedback quickly.
(23:41):
Yeah, that's key. The Polar system provides real
time feedback directly to an iPad on the sideline.
Coaches can monitor up to 60 players simultaneously within a
range of about 200 meters, so they can see instantly if the
team's overall intensity is dropping or if specific
individuals are working too hardor not hard enough, and make
adjustments right there and then.
Real time control. One more in this physiological
(24:03):
section. Yes, and this one is really
pushing the boundaries. It's the Moxie Muscle Oxygen
Monitor. This moves beyond just heart
rate and looks directly at what's happening inside the
muscle tissue itself. It uses near infrared
spectroscopy and IRS technology to measure muscle oxygen
saturation or SMO 2 non invasively and in real time.
OK, NIRSSM O2. That's simplifying heart rate,
(24:26):
tells you how hard the heart is pumping blood.
What does muscle oxygen saturation tell you that's
different? SMO 2 tells you how efficiently
the muscles are actually using the oxygen being delivered by
that blood. It's a direct indicator of the
balance between oxygen supply and oxygen demand within the
working muscle, so it gives you insights into metabolic
efficiency, how well the muscle is generating energy.
(24:47):
And how does a coach use that information?
It allows them to pinpoint very precise physiological thresholds
and training zones for individual athletes.
For example, they can identify the fat Max zone, the intensity
level at which the body maximizes its rate of fat
oxidation for fuel. Why is knowing the Fat Max zone
so valuable? Because training strategically
within or around that zone can improve the body's ability to
(25:10):
burn fat as fuel, which helps spare precious glycogen stores
during long matches. Moxie suggests this zone often
occurs when SMO 2 is at or belowabout 37%.
Having that precise real time SMO two data allows coaches to
prescribe training intensities with incredible accuracy,
ensuring players are getting theright metabolic stimulus to
(25:30):
improve endurance without, you know, completely emptying their
energy tanks unnecessarily. It correlates strongly with
other measures like VO2 Max, butgives a localized muscle
specific picture. Hashtag tag tag D4 now.
Wellness environment and optimization.
Managing the human element. OK.
We've covered movement skills, internal load during exercise,
but performance isn't just aboutwhat happens during training or
(25:53):
games, right? It's a 247 process, managing
recovery, sleep, overall Wellness, even the environment
that's become just as critical. Absolutely.
The modern elite athlete is viewed as a holistic system.
What happens off the pitch is arguably as important as what
happens on it, and this is wherewearable Wellness and recovery
(26:14):
technology has exploded. The two big players everyone
talks about are the W-84 Point Orecovery wristband and the RO
Ring Gen. 3. Right, you see athletes across
all sports wearing these. Now let's start with W app.
Their big focus seems to be sleep, doesn't it?
Yeah, sleep is fundamental to their platform.
The W8 band tracks your sleep stages, slow wave sleep, REM
(26:34):
sleep, light sleep and periods of wakefulness throughout the
night. And they claim the accuracy
rivals laboratory based polysomography, which is the
gold standard for sleep tracking.
And what does it do with all that sleep data?
It synthesizes it along with other metrics like resting heart
rate, heart rate variability, HRV, and respiratory rate into a
single, easy to understand dailyrecovery score.
(26:57):
This score is usually presented with the color code.
Green means you're well recovered and ready for high
strain. Yellow suggests you're OK but
maybe need to moderate intensity.
Red indicates you're fatigued orunder recovered and should
prioritize rest or active recovery.
So it's basically giving the player and the coach a daily
readiness signal. Exactly.
It takes the guesswork out of How do I feel today Arsenal FC
(27:20):
is 1 prominent football club known to use loop extensively
with their players to guide training load decisions based on
objective recovery data. OK, And the aura ring often seen
on the fingers of players, including reportedly at Real
Madrid. How does it differ?
Similar goal, different approach.
Similar goal, optimizing readiness and recovery, but it
leverages slightly different data points collected from the
(27:41):
finger, which is apparently verygood for accurate signal
capture. Aura puts a huge emphasis on
heart rate variability, or HRV. We mentioned HRV with first beat
2. Remind us why HRV is such a key
indicator? HRV is the tiny variation in the
time interval between consecutive heartbeats.
A higher HRV generally indicatesbetter recovery, lower stress,
(28:02):
and a well functioning autonomicnervous system that's ready to
adapt. Aura claims their ring measures
HRV with 98.4% accuracy comparedto a medical grade
electrocardiogram ECG that's incredibly precise for a
consumer wearable. Wow, ECG level accuracy from a
ring. Apparently so.
And like WATR combines HRV with sleep stage analysis, resting
(28:24):
heart rate, and, importantly, body temperature variation to
calculate its own daily readiness score.
It's looking for stability and positive trends in these key
biometric markers. So coaches are getting these
highly accurate, deeply personalbiometric scores every single
day. It allows for incredibly
personalized training adjustments.
But this must raise some questions, right?
We're talking about really intimate data here.
(28:45):
It absolutely does and it's a growing point of discussion and
sometimes tension within professional sports.
You touched on earlier. Studies show a large majority,
something like 78%, of professional footballers have
concerns about how their biometric data might be used or
potentially misused. Yeah, you can imagine, right?
What if your contract negotiation hinges on your
average recovery score? Or what if you feel absolutely
(29:07):
fine mentally ready to play, butyour wearable says you're in the
red zone and the coach benches you based on that data alone?
Exactly. There's a real ethical pipe rope
to walk here between optimizing performance for the team and
respecting player autonomy and privacy.
It highlights why Robust data security protocols, clear
agreements on data ownership andusage, which companies like W
(29:29):
APE and Aura do emphasize, are absolutely crucial as this
technology becomes more embedded.
OK, besides sleep in general recovery, what about specific
environmental factors? Heat, for instance.
Football's played all over the world, often in really
challenging climates. Yeah, managing heat stress is
critical, and for that we have technology like the core body
temperature sensor. This is a wearable sensor, often
(29:51):
worn on a chest strap or stuck to the body, that measures core
body temperature continuously and noninvasively.
Noninvasively so. No need for those ingestible
pills anymore. Exactly.
It provides real time accurate core temp readings and it
calculates something called a heat strain index, typically on
a scale of zero to 10, to quantify the level of heat
(30:13):
stress the athlete is under. This tech was apparently used
quite a bit during the 2022 World Cup in Qatar, where
managing heat, even with stadiumcooling was a major concern.
Temperatures were still around 2126°C.
And the impact of unmanaged heaton performance is massive,
isn't? It it's huge.
Research shows that athletes whocan't effectively manage heat
accumulation can see their performance capability drop by
(30:36):
as much as 26%. That's devastating in a sport
decided by fine margins. But the flip side is also true
if you manage it well. Exactly.
If you use data from sensors like CORD to guide heat
acclimatization protocols and manage intensity during hot
conditions, you can actually boost performance.
Studies show proper heat acclimatization can improve time
(30:56):
trial performance by around 8%. Knowing precisely when an
athlete score temperature is nearing a critical threshold
allows coaches or medical staff to intervene, adjust pacing,
ensure cooling strategies, modify hydration before
performance plummets or worse, heat illness occurs.
And hydration goes hand in hand with heat management.
(31:16):
Any breakthroughs there? Yes, this is another really
exciting area. Nick's biosensors have developed
a wearable patch that monitors hydration status in real time by
actually analyzing the composition of an athlete's
sweat. Analyzing sweat, How does that
work? The patch sticks to the skin,
collects a tiny amount of sweat,and analyzes it on the spot.
It calculates the person's real time whole body sweat rate, how
(31:39):
much fluid they're losing per hour, and crucially, it also
measures the sodium concentration in their sweat.
Why is sodium concentration so important?
Doesn't everyone just need electrolytes?
They do, but the amount varies hugely between individuals.
Some athletes are salty sweatersand lose a lot of sodium, maybe
up to 2000 milligrams per liter of sweat, while others lose much
(31:59):
less, maybe only 200 milligl. If you don't replace sodium
adequately, performance suffers.Cramping risk increases.
NICs provides personalized alerts based on the individual
sweat rate and sodium loss, telling them exactly how much
fluid and how much sodium they need to replenish.
So no more generic drink X amount of sports drink advice.
(32:20):
This is truly personalized hydration strategy.
Precisely. It takes the desk workout.
It's particularly valuable for workouts or matches lasting
longer than, say, 45 minutes, especially in the heat, where
athletes can easily sweat more than a liter per hour.
It ensures they replace exactly what they're losing.
Hashtag tag Tag D5. The frontier of training.
Neurostimulation. OK, we've tracked movement
(32:42):
skills, internal Physiology, recovery environment.
Feels like we've covered the body from every angle.
But there's one more frontier, isn't there?
Something that goes beyond just monitoring or managing the body.
Something that tries to activelyenhance the brain's ability to
learn. Yeah, now we're really getting
into the cutting edge. We're talking about
neurostimulation, specifically using technology like the Halo
(33:02):
Sport 2 Neurostimulation headset.
Neurostimulation headset. It sounds like something out of
science fiction. What does it actually do?
It uses a technique called transcranial direct current
stimulation, or TDCS. Basically, the headset has
primals that sit on the scalp over the motor cortex, the part
of the brain that controls movement.
It delivers a very weak, safe electrical current, usually up
(33:24):
to about two milliamps to that specific brain region.
OK. Why would you want to send
electrical currents into your brain before you train?
What's the goal? The goal is to temporarily
increase neuroplasticity in the motor cortex.
Think of plasticity as the brains ability to change, adapt
and learn new skills by forming and strengthening neural
connections. The TDCS from Halo Sport is
(33:47):
designed to put the motor cortexinto a state of hyperplasticity,
or heightened readiness to learnfor a short period.
So it's like warming up the brain circuits responsible for
movement skills. That's a good analogy.
It makes those neurons more excitable, more receptive to
forming the connections needed to master a physical skill.
So when the athlete then goes and practices that skill,
(34:08):
whether it's perfecting a golf swing, learning a complex
gymnastic routine, or refining their penalty kick technique in
football, the theory is that thebrain learns faster, the muscle
memory forms more efficiently, and the skill improvement is
accelerated because the underlying neural pathways are
being strengthened more effectively during that primed
(34:28):
window. And is there evidence this
actually works? Does zapping your brain make you
better at sports? Well, the company points to
clinical studies, some independent, some internal.
One often cited study involved amotor learning task like dart
throwing, where participants using the TDCS before practice
showed significantly faster improvement rates, sometimes
quoted as high as 50% faster learning compared to a control
(34:52):
group doing the same practice without stimulation. 50% faster
learning. That's potentially huge.
How do athletes typically use it?
The standard protocol is a 20 minute neural priming session
wearing the headset immediately before a training session
focused on skill development or intense physical output.
This hyperplasticity effect is thought to last for about an
(35:12):
hour afterwards, so they aim to maximize that window for high
quality practice. This feels like a real paradigm
shift doesn't it? Moving from just measuring and
managing the athletes current state to actively intervening to
accelerate their potential. It really does.
It's moving from observation andoptimization to active
enhancement. And that's why you see this kind
of technology TDCS being explored and adopted not just in
(35:36):
niche sports, but across major leagues like the NFLNBAMLB and
in elite military training, too.They're constantly looking for
that next edge, and priming the brain itself is, well, pretty
compelling Frontier. So yeah, when you sit back and
look at it all, we've gone from the raw, visceral emotion of a
youth tournament elimination decided by a single goal
(35:57):
different statistic, all the waydown to devices monitoring the
oxygen levels and individual muscle fibers in real time, and
even headsets aiming to boost the brains learning speed with
electrical currents. The key take away is the
synthesis. It's not about any single
gadget, is it? Not at all.
The truly successful teams, the ones consistently performing at
the elite level, whether it's developing young talent OR
(36:17):
competing for Champions League titles, they aren't just relying
on one piece of tech, they're building this comprehensive,
interconnected ecosystem. They're layering GPS data with
biomechanical insights from footsensors, overlaying that with
internal physiological load fromheart rate and SMO 2 monitors,
and managing it all based on recovery scores from sleep
trackers and readiness data. They're building these
(36:40):
incredibly detailed, dynamic, almost predictive profiles of
every single athlete. The era of relying purely on
coach's intuition or generic training plans that's well and
truly over at the top level isn't.
It it absolutely is. The data confirms the shift
every single aspect of preparingan athlete, from designing
training drills, to managing injury risk using things like
(37:02):
ECLR, to ensuring they peek perfectly for that one crucial
knockout match using readiness squares, it's all now
fundamentally intertwined with sports science and technology.
It has become a data-driven endeavor through and through.
And the performance gains, thesetools on lock are undeniable.
They're transforming what athletes are capable of.
But as we've touched on, this technological revolution forces
(37:25):
us to confront a really significant and frankly quite
challenging reality that's only going to become more prominent.
All this technology we spent thelast while unpacking it,
generates vast quantities of incredibly sensitive personal
biometric data about the players.
Their sleep patterns, their hearts response to stress, their
muscle efficiency, maybe even predispositions to certain
(37:45):
injuries based on bio mechanics or genetics, potentially even
how their brain responds to learning stimuli.
It's deeply personal stuff. And that leads us to the final
really provocative question we wanted to leave you at the
listener thinking about today asthis kind of performance
technology becomes not just advantageous, but potentially
mandatory for competing at the highest level.
(38:05):
As players increasingly become walking, talking constant
streams of biometric data, how do we as a sporting community,
as a society, fundamentally manage player privacy and data
ownership in the future of elitesports?
How do we ensure we protect the human being at the center of all
these sensors?
