KINEMATIC, KINETIC, AND ANTHROPOMETRIC DETERMINANTS OF THE COUNTERMOVEMENT JUMP IN VOLLEYBALL PLAYERS
Abstract
This study investigates the biomechanical characteristics of the countermovement jump in volleyball players based on kinematic, kinetic, and anthropometric indicators. Parameters of center of gravity motion, joint angles, vertical ground reaction forces, and mechanical work were analyzed during the preparation, flight, and landing phases. The results demonstrate relatively stable jump height, center of gravity velocity, and mechanical work output, indicating homogeneous explosive performance among athletes. During landing, the knee and ankle joints played a dominant role in impact absorption, while increased variability in frontal and transverse plane motions reflected individual stabilization strategies. These findings provide valuable insights for improving jumping technique and reducing injury risk in volleyball players performing repeated high-intensity vertical actions.
