ABSTRACT:
The purpose of the study was to investigate the outcome of plyometric training and plyometric training with protein supplementation on explosive power. To achieve the purpose of the study, forty-five men inter collegiate volleyball players were selected as subjects. The age, height and weight of the subjects ranged from 18 to 22 years, 162 to 175 centimetres and 60 to 75 kilograms respectively. The selected subjects were randomly assigned into three equal groups of 15 subjects each. Group I underwent plyometric training, group II underwent plyometric training with protein supplementation and group III acted as control. The experimental groups were trained up in which two modes of training were given independently with separate participants in each group. The pre test data were collected prior to the training programme and post test data were collected immediately after the twelve weeks of plyometric training and plyometric training with protein supplementation from two experimental groups and a control group on selected dependent variables were statistically analyzed to find out the significant difference if any, by applying independent T test and the analysis of covariance (ANCOVA). Since three groups were involved, whenever the obtained ‘F’ ratio for adjusted post test means was found to be significant, the Scheffe’s test was applied as post hoc test to determine the paired mean differences. In all the cases level of confidence was fixed at 0.05 for significance.
