Abstract:
The study was to find out the effect of resistance training on physical variables of adolescent male tennis players. To achieve the purpose of the study, thirty adolescent male tennis players were randomly selected from the National Sports School, Ajjanoor, Coimbatore and their age 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 resistance training for a period of twelve weeks and group-II acted as control who did not participate in any special training other than routine. The physical variables such as speed, explosive power and flexibility were selected as dependent variables. Speed was tested by thirty mts (Dash) in seconds, leg Explosive power was tested by standing broad jump in meters, flexibility was tested by sit and reach in centimetres. 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 0.05 level of confidence was fixed. The result of the study shows that, there was a significant improvement takes place on speed, explosive power, flexibility of adolescent male tennis players due to the effect of twelve weeks of resistance training. And also concluded that, there was a significant difference exists between experimental and control groups on speed, leg explosive power, flexibility. The control group did not improve the selected criterion variables.
