Abstract :
The purpose of the present study was to find the effect of varied intensities of plyometric training on speed and explosive power. For this purpose, sixty male players of studying in various departments of Manipal University, Mangalore, with the age group of 18 – 25 years were selected. They were divided into four equal groups, each group consisted of fifteen subjects, in which group – I (n = 15) underwent low intensity plyometric training (LPTG), group – II (n = 15) underwent medium intensity plyometric training (MPTG), group – III (n = 15) underwent high intensity plyometric training (HPTG) and group – IV (n=15) remained as control. The training period was three days in a week for twelve weeks. The selected criterion variables such as speed and explosive power were assessed by administering 50 meters run and Sergeant jump test. The Analysis of Covariance (ANCOVA) was applied as statistical tool, to find out which group has significantly improved the speed and explosive power. Whenever the adjusted post-test mean ‘f’ ratio was significant, the Scheffé S was used as post hoc test. It was concluded after applying the statistical tool, that three training groups, when compared with the control group. The training period for the present study was twelve weeks and three days per week (alternative days). It was concluded from the result of the study all the training groups such as, low intensity plyometric (LPTG) training, medium intensity plyometric (MPTG) and high intensity plyometric (HPTG) training group were significantly improved their speed and explosive power in terms of vertical distances and moreover, there was no significant difference was occurred between the training groups on speed and explosive power in terms of vertical distances after their respective training programmes.
