The selected subjects were divided in two equal groups fifteen each namely circuit training group and control group.

The variables namely leg explosive power was selected as criterion variables. The subjects of the two groups were tested on leg explosive power by using vertical jump at prior and immediately after the training period. The collected data were analyzed statistically through analysis of covariance (ANCOVA) to find out the significant differences, if any between the groups. The 0.05 level of confidence was fixed to the level of significance which was considered as an appropriate.
