INVESTIGATION ON THE CHANGES ON LEG STRENGTH OF SOCCER PLAYERS DUE TO HIGH INTENSITY INTERVAL TRAINING IN HARD AND SAND SURFACE

This study was to find out the investigation on the changes on leg strength of soccer players due to high intensity interval training in hard and sand surface. To achieve the purpose of the study forty-five male soccer players was selected as the subjects from Annamalai University, Chidambaram, Tamil Nadu, India. The age of the subjects was ranged from 18 to 23 years. The selected subjects were assigned into three groups of fifteen each. Group-I (n=15) underwent HIIT in sand surface, Group-II (n=15) underwent HIIT in hard surface and group-III (n=15) was acted as control who did not participate in any training apart from regular play of soccer. Each group consisted of 15 subjects and training was given for three days a week for twelve weeks. Prior after the training period leg strength was measured by 1 RM test. Analysis of Covariance (ANCOVA) was applied as statistical tool for the present study. The Scheffé S test was used as posthoc 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, high intensity interval training in hard and sand surface group influence on leg strength when compared with control group. From the results of the study, it was concluded that high intensity interval training in sand surface group was better than hard surface group for improve leg strength among male soccer players
