The purpose of this investigation was to find out the comparative effect of different heights of depth jumping on vertical jumping ability. Forty boys of classes eight from Ram Krishna Vidhya Mandir , Morar (Gwalior) were selected at random as subjects and their average age was 13 years. The subjects were divided into four equated groups by computing means and standard deviation. Group A was trained in depth jump on 35cm and group B in 40cm and group C in 45cm for a periods of six weeks 3 days per week. The A, B, C experimental groups and group D served as control group. Vertical jumping ability was taken as dependant variable for this investigation. To determine which treatment variable proved to be most effective in improving vertical jumping ability. F-test was applied and a post hoc test using L.S.D. test was used. The results revealed that depth jump is an effective method as compared to the control group and depth jump on 35cm, 40cm, 45cm are equally effective in enhancing vertical jumping ability of the subjects.
