The purpose of the study was to investigate the effect of interval training on explosive power among school students. For this study the investigator selected 30 school students from Bengaluru, Karnataka. The age of the subjects was between 15 and 17 years. The subjects were divided into two group consists 15 subjects in each group. The random group design was used as experimental design for this study. The variable to be used in the present study was assessed from all subjects before the experiments. It was assumed as pre-test. After completion of treatment they were tested again as it was in the pre-test on all variables used in the present study. This test was assumed as post-test. The data collected for statistical treatment to find out significant difference between the pre test and post test means by computing dependent‘t’ test. In all cases 0.05 level of confidence was utilized to test the significance. The result of the experimental group showed significant improvement on explosive power when compared to the control group.
