Abstract:

The purpose of the study is to find out the effect of isolated and combined weight and plyometric training and detraining on explosive power in terms of vertical distance. To achieve this purpose sixty male students studying in various polytechnic colleges in and around Perambalur, Tamilnadu during the year 2019-2020 were selected as subjects. The age of the subjects were ranged from 19 to 25 years. They were divided into four equal groups of fifteen each as three experimental groups and one control group, in which the group – I (n = 15) underwent weight training, group – II (n = 15) underwent plyometric training and group – III (n = 15) underwent the combination training for three days per week for twelve weeks followed by detraining for four weeks of ten days interval and group – IV (n = 15) acted as control who did not participate any special training apart from the regular program of the curriculum. After the training sessions, the detraining effects have been assessed by way of every 10 days from the last session of the training. Like that 4 cessations have been followed. During the detraining sessions, the trainees had been suggested not to do any unique exercises other than regular routines. The explosive power in terms of vertical distance was assessed by using leg lift with dynamometer and the collected data was statistically analyzed by two way (3 x 6) factorial ANOVA with last factor repeated measures. Whenever F-ratio obtained for interaction effect was found to be significant, the simple effect test was applied as a follow up test. Since, four groups and six different stages of test were compared, whenever obtained F-ratio value in the simple effect was significant the Scheffe’s test was applied as post hoc test to determine the paired mean differences, if any and in all the cases 0.05 level of significance was fixed. The result of the study shows that there was a significant improvement for all the training groups on explosive power in terms of vertical distance. It was also found that there was no significant difference occurred between the training groups on explosive power in terms of vertical distance during the first, second and third cessation periods. The explosive power in terms of vertical distance was decreased significantly at the time of all fourth cessation period for the training groups.
