Fatigue alters the biomechanical contribution of lower extremity joints during a stretch-shortening cycle task.

This study aimed to explore the effect of fatigue on the biomechanical contribution of the lower extremity joints during a typical stretch-shortening cycle (SSC) task.15 male athletes completed drop jump (DJ) under pre- and post-fatigue. Vicon motion capture system and 3D Kistler force plates were used to collect kinematics and ground reaction force data simultaneously.Under fatigue condition, 1) the DJ height decreased; the touchdown angle of...
