Effect of Different Packages of Training on Serving Ability of Male Volleyball Players

INTRODUCTION

Plyometrics is a type of exercise training designed to produce fast, powerful movements, and improve the functions of the nervous system, generally for the purpose of improving performance in sports. Plyometric movements, in which a muscle is loaded and then contracted in rapid sequence, use the strength, elasticity and innervations of muscle and surrounding tissues to jump higher, run faster, throw farther, or hit harder, depending on the desired training goal. Plyometrics is used to increase the speed or force of muscular contractions, providing explosiveness for a variety of sport-specific activities. Circuit training is a common method of interval training. Circuit training consists of a consecutive series of times exercises performed one after the other with varying amounts of res between each exercise. Circuit training is called station training when more than one set of exercises for a particular muscle group of groups are performed at a station of another fixed location. Station training then refers to the organization of training.

1. To measure the influence of plyometric training treatment on the serving ability of volleyball players. 2. To evaluate the impact of circuit training treatment on the serving ability of volleyball players. 3. To understand the changes between plyometric training, circuit training and combined training on serving ability of volleyball player.

STATEMENT OF THE PROBLEM

The purpose of the study is to investigate the effect of different packages of training on serving ability of male volleyball players.

► It was hypothesized that may be significant improvement on serving ability of male volleyball players due to the plyometric ► It was hypothesized that may be the combined training group is better than the other two training group and control groups on serving ability of male volleyball players.

The purpose of the study was to find out the ―Effect of different packages of training on serving ability of male volleyball players‖. For the purpose of the study sixty male volleyball players were selected as subjects in and around Guntur District of Andhra Pradesh and their age ranged from 18 to 21 years. The subjects chosen for the study were divided into four equal groups and designated as experimental group ‗A‘ experimental group ‗B‘ experimental group ‗C‘ and control group ‗D‘ Plyometirc training were given to group ‗A‘ circuit training were given to group ‗B‘. Combined Training were given to group ‗C‘ and the control group ‗D‘ were restricted to participate in any activities. The trainings were given for a period of twelve weeks. The obtained data further analyzed by using analysis of covariance and which was further subjects of scheff‘s post hoc test, wherever the F- ratio was found significant.

It deals with at the analysis of data collected from samples under study four groups namely Plyometric training, Circuit training. Combined training and the control groups were analyzed for the differences in their measures of serving ability among volleyball players in relation to pretest, post-test and adjusted post-test mean values by applying the analysis of covariance. To test the obtained results on serving ability, the level of significance 0.05 was chosen and considered as sufficient for the study.

The above table I shows that the obtained ‗F‘ ratio in pre-test (F=0.003, P>0.005) among four groups found to be insignificant in serving. Further it can be seen that significant differences exist in post-test (F=8.285, P<0.005) and adjusted post-test (F=17.904, P<0.05). Based on the result of the study training group when compare with control group.

The above table II shows that the significant differences exist between the PTG & CG, CTG & CG and PTGCTG & CG, whereas in case of PTG & CTG, PTG & PTGCTG, CTG & PTGCTG found insignificant paired mean differences at 0.05 level of confidence.

► In the first hypothesized mention that may be significant improvement on explosive power of male volleyball players due to the Plyometric training, circuit training and combined training when compared with control group. Hence research first hypothesis accepted. ► In the second hypothesized mentioned that may be the combined training group is better than the other two training group and control groups on explosive power of male volleyball players. Hence research second hypothesis rejected.

Based on the results of the study the following conclusion where drawn:

volleyball players when compared with the control group. 2. The study found no significant differences between three experimental groups volleyball players namely plyometric training group, circuit training group and combined training group volleyball players 3. It is suggested that volleyball coach may apply isolated and combined training of plyometric and circuit training to develop serving ability of volleyball players.
