Abstract:
This study was to find out the combined and isolated effect of ladder and medicine ball training on explosive power among school students. The purpose of the study one hundred and twenty (120) high school boys were selected randomly as subjects from in and around Thathanur, Tamil Nadu, India. The selected subjects were randomly assigned into one of four groups of thirty (n=30) each. The group I (n=30) underwent combined training, group II (n=30) underwent ladder training, group III (n=30) underwent medicine ball training for a duration of twelve weeks with three days per week, in addition to the regular schedule and group IV (n=30) had acted as control group which did not undergo, any special training except their leisure time pursuit. Students who have participated on the school teams and are healthy guys will make up the participants in these experimental groups. The subjects were tested on Explosive power before and after the training period. Prior after the training period explosive power were measured by using standing broad jump. Analysis of Covariance (ANCOVA) was applied as statistical tool for the present study. The Scheffé S test was used as post-hoc test at whatever point the ‘F’ - ratio of the adjusted post-test means were discovered to be significant at 0.05 level of significance. Both, ladder, medicine ball training and combined training group influence on explosive power when compared with control group. Combined (medicine ball and ladder training) may have better influence on muscular endurance of school students.
