Effect of plyometric training on physiological variables of adolescent male tennis players

Abstract

The study was designed to investigate the effect of Plyometric training on physiological variables of adolescent male tennis players. To investigate the study, thirty adolescent male tennis players were randomly selected from National Sports School, Ajjanoor, Coimbatore and their age were ranged between 14 and 17 years. The subjects were randomly assigned to two equal groups (n=15). All the subjects were divided in to two groups with 15 subjects each as experimental and control group. Group-I underwent Plyometric training for a period of twelve weeks and group-II acted as control who did not participate in any special training other than the regular routine. The physiological variables such as resting heart rate and breath holding time were selected as dependent variables. Pre and post-test random group design was used for this study. The dependent ‘t’ test was applied to determine the difference between the means of two group. To find out whether there was any significant difference between the experimental and control groups. To test the level of significant of difference between the means 0.05level of confidence was fixed. The result of the study shows that, there was a significant improvement takes place on resting heart rate and breath holding time of adolescent male tennis players due to the effect of twelve weeks of Plyometric training. And also concluded that, there was a significant difference exists between experimental and control groups in resting heart rate and breathe holding time. The control group did not improve the selected criterion variables.
