THE MAXIMUM ANGULAR VELOCITY OF VOLLEYBALL PLAYERS ENTERING THE BALL INTO PLAY

Abstract

This study focuses on the kinematic analysis of maximum angular velocity in volleyball players during ball-entry actions, such as serving and spiking, using 3D motion analysis (3D MA) technology. The research aims to evaluate how angular velocities in key body segments—particularly the shoulders, hips, knees, and ankles—contribute to performance effectiveness. By analyzing movements like shoulder flexion, extension, abduction, and adduction, the study provides insights into the biomechanical factors that influence the power and precision of volleyball serves and spikes. A candidate athlete for Master of Sports in volleyball participated in the study, with movements captured by a high-resolution 3D motion capture system in a controlled laboratory environment. The results highlight significant asymmetries between the dominant and non-dominant sides, reflecting the player’s reliance on one side for generating power. The research identifies specific kinematic indicators crucial for achieving optimal performance and suggests training programs that enhance shoulder strength, flexibility, and balance, while reducing injury risk.
