Effect of Resisted Sprint versus Plyometric Training on Leg Strength of Male Sprinters

Abstract

The purpose of the study was to find out the effect of resisted sprint (RS) versus plyometric training (PT) on the leg strength of male sprinters. To achieve the purpose of the study the researcher selected thirty intercollegiate level male sprinters as subjects. They were divided into three equal groups of ten sprinters. Group-I performed RS training (n = 10), Group-II performed PT (n = 10), and Group-III acted as control (n = 10). The age of the selected subjects was ranged from 18 to 22 years. The statistical procedure was “t-test” and percentage changes were used Further, analysis of covariance (ANCOVA) was used to determine the significant difference existing between pretest and posttest on stride frequency. When the obtained “F ratio” value in the ANCOVA test was significant the Scheffe’s test was applied as a post hoc test to determine the paired mean differences if any. The results showed that twelve weeks of RS and PT considerably improved the leg strength of the male sprinters, whereas PT was significantly better than RS training. The result produced a 3.71% percentage of changes in leg strength due to RS training and 7.44% of changes due to PT.
