摘要：AbstractThis study focused on the effect of a 4-week, plyometric training period on lower body muscle electromyography(EMG) changes in university futsal players. Thus, 14 players of a varsity futsal team with an average age of 19.1-22.6, height of 159.4-182.5 centimeters, and weight of 58.9-76.9 kilograms were chosen. The subjects participated in four weekly 45-60minute training sessions in a 4 week period. Before and after the 4 week period, the EMG for the biceps femoris and gracilis were checked. A paired t-test with α=0.05 was used. The results revealed that 4 weeks of plyometric training had a significant effect (p<0.05) on the EMG of the biceps femoris while performing the Squat Movement(absolute strength) but the EMG for the biceps femoris was insignificant (p>0.05) for the vertical jump(explosive power).
