Abstract

 Volleyball is one of the most played games in Indian School going population. Vertical jump height is an essential part in volleyball which can be achieved by strengthening the lower leg musculature. Thus the 6 weeks plyometric training protocol is added to see its results on the strength of lower leg musculature among high school amateur male volleyball players. The subjects (n = 40; age = 10 - 16 years; mean = 12 ± 1.00 years) jumping reach Height (mean) = 169.00 ± 1.00 cm) were divided equally into 2 groups called as group A (Experimental) and group B (Control) respectively by simple random sampling method. Group A received the 6 weeks plyometric training protocol and conventional training while group B received only conventional training. Sargent jump test was used to assess the jump heights pre and post at the end of 6 weeks. Unpaired t-test was used to compare the results between the groups. Group A showed significant increase in the difference between the jumping and standing reach heights at the end of 6 weeks (mean difference in the height = 34.25 cm; p-value < 0.05) than in Group B (mean difference in the height = 25.15 cm; p-value < 0.05) at the end of 6 weeks. Also, there is significant improvement in Jumping reach height in Group A (pre = 188.05 cm; post = 203.00 cm) than in Group B (pre = 187.20 cm; post = 195.15 cm). Group A showed 43.65% (mean = 34.25 cm; SD = 7.59) increase while Group B achieved 31.61% (mean = 25.15 cm; SD = 3.73) increase with their initial vertical jump height Both the training protocols are effective in improving vertical jump height but the 6 weeks plyometric training protocol is more effective in improving vertical jump than the conventional training among high school amateur male volleyball players.
