Effective sprint training requires an in-depth understanding of the physiological demands sprinters face as they accelerate and maintain high speeds. This deep dive will explore a study by Dorn, Schache, and Pandy (2012) highlighting the muscular strategy shifts that occur as sprinters increase their running speed. This article explores the findings of their study, discusses the key muscular adaptations, and provides practical implications for coaches working with sprinters and distance runners.
Key Findings
Dorn et al. (2012) revealed that as athletes increase their speed, they shift from relying on the ankle plantarflexors (soleus and gastrocnemius) to the hip muscles for achieving further acceleration. This change occurs around the 7 m/s mark, which is particularly relevant for sprinters who race at speeds consistently above this threshold.
