Joint Stiffness and Energy Contribution during Drop Jump in Fatigued and Non-fatigued Conditions

Repetitive movements in training or competitions will inevitably lead to neuromuscular fatigue. It is still unclear about the specific influence of induced fatigue on drop jump biomechanics, e.g., joint energy contribution and stiffness. PURPOSE: To examine the differences in joint energy contribution and stiffness before and after fatigue, further exploring how fatigue affects drop jump performance. METHODS: 15 male participants were required...
