Abstract :

Purpose of the study was to analyze and understand the relation between knee angle and blocking performance in volleyball. Twenty four male volleyball players within the age ranged from 14 to 22 years were selected as subjects. Performance of blocking in volleyball was measured for different knee flexion within the range of 60? to 130?. Knee angle for jumping was controlled by a dip regulator. The knee angle was measured by a manual Goniometer. Results indicated that the jump of the player during blocking performance increased with the increase of knee angle from 60? to 110? and there after the blocking performance decreased with increase of knee angle. The highest blocking performance was obtained with the knee angle of 110?. Values of coefficient of correlation confirmed the positive relation between knee angle and blocking performance for the range from 60? to 110? of knee angle and negative relation for the range from 110? to 130? of knee angle.
