Abstract :

The purpose of this study was to compare the selected kinematic variables of Jump Spike Service between National and University level volleyball players. Ten (5 from each group) male volleyball players who represented National and University were selected as the subject from LNUPE, Gwalior. The age of the subjects was ranged from 19 to 25 and all subjects were right–handed volleyball players. The players were filmed from their right side and for that purpose the Digital photography (Nikon D–100) was employed in the sagittal plane to register the technique of Jump Spike Service at moment execution. The selected linear and angular kinematic variables were height of center of gravity of player and ankle joint, knee joint, hip joint, shoulder joint, elbow joint and wrist joint. By joint point method, stick figures were prepared from the photographs to measure the angles and by segmentation method the center of gravity of players were calculated at selected moments. For statistical analysis of the data t–test was employed. The finding of the study revealed the no significant difference between National and University level male Volleyball players in the Jump Spike Service.
