SKILL ANALYSIS OF VOLLEYBALL SERVE THROUGH KINEMATIC APPLICATIONS

Dr.Mandeep Singh

Abstract

Biomechanical principles are applied by scientists in a number of fields in addressing problems related to human health and performance. This study had been taken to biomechanically analyze the technique of Overhead serve in Volley ball.   It was hypothesized that there may be significant relationship between the selected kinematical variables with the performance of the volleyball players in overhead serve. Ten male national players of Volleyball were selected.  The age of the selected layers were between 20 to 24 years. The study included the  kinematical variables namely Ankle Joint (left), Ankle Joint (right), Knee Joint (left), Knee Joint (right), Hip Joint (left), Hip Joint (right), Shoulder Joint (left), Shoulder Joint (right), Elbow Joint (left), Elbow joint  (right), Wrist joint (left), Wrist Joint (right), Height of C.G at moment stance and Height of C.G  at moment execution for analyzing the technique of overhead serve of volleyball. In the study motion analyzer software motion pro and simi machix is used to asses the selected biomechanical variables. The criterion measure for this study was the performance of selected subjects in overhead serves as assessed by Russell-Lange test of volleyball serve. The product moment correlation (Pearson) was used in order to find out the relationship between selected kinematical variables with the performance of volleyball player’s in overhead serve of Volleyball.  The results have shown that all the selected kinematical variables had insignificant relationship with the performance of subjects in overhead serve in volleyball.
