Alterations in Spiking Following Muscle Fatigue in Volleyball Players

This study aims (1)to investigate the effects of repetitive functional overhead movements targeting shoulder and scapular muscles on glenohumeral and scapular kinematics and muscle activation during the arm cocking and acceleration of spiking, and changes in subacromial structures in healthy recreational volleyball players; (2) to compare these fatigue-related changes between athletes with good and poor shoulder motor control.
