Abstract
The purpose of this study was to determine how mechanical energy is transferred, generated, and absorbed during maximal speed sprint running in semi-elite football players. To perform the segmental power analysis, we collected 3-D kinematics and ground reaction force data during maximum speed sprinting. During late swing, the thigh, shank, and foot showed net energy outflow (negative), indicating energy transfer to the pelvis/trunk or dissipated. During the first half of stance the hip was the prime generator while the knee and ankle absorbed energy. In the second half of stance, the hip transitioned to absorbing energy while the knee and ankle shifted to energy generation through to toe off. The hip and ankle joints were the primary sources of power generation, whereas the knee demonstrates a more complex absorption–generation transition, particularly around mid-stance.
