Purpose of the present study was to determine the effect of 9 weeks of training based on various jumping exercises on vertical force distribution and EMG pattern in school children. Forty school children (12 male and 28 female) aged between 13 to 17 years participated in this study. Subjects were divided evenly into 3 experimental groups: Group 1 (training based on jumps), Group 2 (training based on hops), Group 3 (training based on box drills) and a control group - Group 4. Intervention programme had been administered on the experimental groups for 9 weeks. During the 1st three weeks, the subjects were exercising once a week, followed by 3 weeks of exercising twice a week with last 3 weeks exercising thrice a week. No intervention programme was administered to the control group. Subjects were evaluated before, after 3 weeks (mid-test 1), 6 weeks (mid-test 2) and 9 weeks (post-test) in counter movement jump (CMJ), continuous jump with bent legs (CJb) and drop jump (DJ) with registration of jumps' characteristics and EMG. As a result, all intervention groups showed significant improvement in jump height and power within group between tests (p<0.001). By CMJ test, hop training brought highest improvements in jump height (27.9%) (p<0.001) and power (9.70%) (p
