A comparative study on effects of strength and plyometric training to improve performance in an open hand volley ball serve and spike

Objective: To improve performance of serve and spike velocity through strength and plyometric training. The modern game of volleyball requires to play in all positions during match. At times player become a spikier, blocker, attacker, server and defender. As a consequence a player is expected to work on programme designed to improve strength, agility and flexibility. The two main techniques which are important in play serve and spike. A definite degree of strength of wrist and shoulder muscle is required for serve and spiking. Materials and Methods: Using randomized sampling experimental study at the college level, 30 students had participated in the study, study has been conducted for 6 weeks – 2 sessions/day. Tools used included an Electronic stop watch were used to measure the time of the ball during service and spiking, steel tape is used to measure the distance of spike and serve, push pull dynamometer used to measure the strength. Multiple Regression Equation To predict the velocity of the service and the velocity of the spiked ball with the help of selected independent variables i.e.
