Beginner vs. Elite Sprinters
🏃🏻♂️ Elite sprinters have ~5% higher stride length and ~4% higher stride rate. (Via Essentials of Strength Training and Conditioning book)
But the biggest difference:
📈 300% higher force production through the plantar flexors in 0.1 sec.
Plyometrics, calf strength training, and sprint training can improve Achilles tendon stiffness and calf rate of force production.
