ABSTRACT:
Resistance training is recognised as one of the most effective and efficient trainings to enhance various aspects of motor fitness. Standard and scientific methods of resistance training are necessary in the field of sports to improve the levels of performance. The purpose of the present study was to find out the effect of varied intensities of resistance training on explosive power. The subjects for this study were randomly selected from among the first year bachelor of physical education students during the year 2017-2018, Department of Physical Education and sports sciences, Annamalai University. Their age ranged between 18 to 21 years and they were segregated into four groups, each group consisting of 15 subjects, following the routine procedures of selection of subjects. The first group underwent high intensity resistance training programme, the second group underwent medium intensity resistance training programme the third group underwent low intensity resistance training programme and the fourth group acted as control and did not undergo any systematic training programme. Thus the high, medium and low intensity resistance training were consisted as three experimental variables and explosive power consider as one criterion variable for the present study. All the subjects were tested on explosive power before the commencement of the training programme. Thereafter three varied intensities of resistance training were given 3 days a week for 10 weeks for the three experimental groups and the control group did not participate in any systematic programme. The subjects were tested again on explosive power after the completion of training programme. To nullify the variation in the pre-test means, analysis of covariance (ANCOVA) was applied and the adjusted post-test means were tested for significance. If the ‘F’ ratio was significant Scheffe’s post-hoc test was applied to find out the significant differences if any, among the paired means. The level of significance was set at 0.05 level. the results shows that, high, medium and low intensity training groups showed significant improvement in explosive power as compared to control group. The medium intensity resistance training programme significantly improved explosive power when compared to high and low intensity groups. However there was no significant difference in the explosive power between high and low intensity groups. So it is concluded that the medium intensity training is better than high and low intensity resistance training in improving explosive power.
