The Effects of Plyometric Training Combined with Weight Training on Leg Power in Football Players

Abstract

         This study was intended to determine the effects of plyometric training combined with weight training on leg power in football players. Thirty football players aged between 19 and 24 years from a university were randomly divided into two groups. The experimental group was trained by plyometric training combined with a weight training program (n = 15); the control group was trained with a regular training program (n = 15). The two groups were trained for 8 weeks, 2 days a week, 1 hour per day. Leg power was measured pre-test and 2 post-tests (4^th and 8^th week) using the Margaria-Kalamen Test. The data were statistically analyzed as mean and standard deviation by using t-test, and repeated measure of variance with pairwise a comparison by Bonferroni’s Method.

         The research finding were as follows.

         The experimental group had the mean leg muscle power. After the 4th week of training more than before. And after the 8th week of training, it was significantly more than before and after the 4th week of training at the .05 level.

         The control group had average leg muscle power. After the 8th week training, it was significantly higher than before and after the 4th week at the .05 level.

         After 8 weeks of training, the experimental group had higher mean leg muscle power than the control group. statistically significant at the .05 level
