The capacity to rapidly generate and apply a great amount of force seems play key role in sprint running. However, it has recently been shown that, for sprinters, the technical ability effectively orient onto ground is more important than its total amount. force-vector theory proposed guide coaches selecting most adequate exercises comprehensively develop neuromechanical qualities related distinct phases sprinting. This study aimed compare relationships between vertically-directed (loaded...
