Abstract
Background: Volleyball has become a rapidly growing sport worldwide. Mastery of technique is crucial to achieving optimal performance. The jump serve is one of the most important techniques in volleyball, as it is essential for initiating play. Method: Therefore, it is necessary to investigate the mastery of this technique through a biomechanical approach. 15 male professional athletes and 15 male amateur athletes participated in this study. The participants performed the jump serve technique, and the data were analyzed using a biomechanical analysis approach. Kinematic parameters measured included the angular velocity of the elbow and shoulder, the maximum angle of the elbow and shoulder, as well as data on ball speed, jump height, and step length. Subsequently, the participants performed jump serves with maximum effort, aiming to land the ball within designated target zones. Results: The results of the study show that there is a significant difference in ball speed. Additionally, there were differences in kinematic parameters, specifically the angular velocity of the elbow and shoulder. Professional athletes demonstrated higher angular velocities in both the elbow and shoulder compared to amateurs. Conclusion: Furthermore, there was a significant difference between professionals and amateurs in maximum elbow flexion angle, but no difference was found in shoulder hyperextension. Based on these findings, it is expected that coaches and athletes will focus on training the kinematic parameters that influence the jump serve technique, as the jump serve is a crucial technique for initiating play in volleyball.
