Effects of low intensity plyometric training combined with aerobic training on leg explosive power of school volleyball players

The purpose of the study was to find out the effects of low Intensity plyometric training combined with aerobic training on leg explosive power of school volleyball players. To achieve the purpose of the study, thirty school volleyball players in, JSS Public School, siddartha layout, Mysore. Were selected as subject at random and their age group range between 13to 15 years. The study was formulated as pre and post test random group design, in which thirty subject were divided into three equal groups. The experimental group-1 (n=10, LI-PT) underwent low intensity plyometric Training, experimental group-2 (n=10, LI-PT-AT) underwent low intensity plyometric training combined with aerobic training and group 3 served as control group (n=10, CG) did not undergo any specific training. In this study, two training programme were adopted as independent variable, i.e., low intensity plyometric training, and low intensity plyometric training combined with aerobic training. The leg explosive power was selected as dependent variable; it was measured by vertical jump test and recorded in centimeters. The selected two treatment group's was performed three days in a week for the period of eight weeks, as per the stipulated training program. The leg explosive power was collected before and after the training period. The collected pre and post data was critically analyzed with apt statistical tool of analysis of co-variance (ANCOVA), for observed the significant adjusted post-test mean difference of three groups with respect to each parameter. The Scheffe's post hoc test was used to find out pair-wise comparisons between groups with respect to each parameter. To test the hypothesis 0.05 level of significant was fixed in this study. The results proved that the low intensity plyometric training combined with aerobic training produce significant improvement on leg explosive power rather than the low intensity plyometric training and control group.
