Study: Heat Acclimation Improves Exercise Performance

Heat adversely affects the body’s ability to produce work, but strategic utilization of heat in a training regimen can bring about power performance increases. Learn what Dr. Chris Minson, one of the leading experts and researchers on this topic, learned as he was executing his study of how Heat Acclimation Improves Exercise Performance in Episode 1 of the Science of Getting Faster Podcast!
