EFFECTIVENESS OF PLYOMETRIC TRAINING WITH BLOOD FLOW RESTRICTION ON EXPLOSIVE POWERIN Taekwondo ATHLETES

The purpose of this study was to investigate the effects of plyometric training with blood flow restriction on explosive power in Taekwondo athletes. Twenty Taekwondo athletes who were volunteers to participate in the research (under 17 years old, at least 2 years in the provincial league and the minimum red belt), were selected .athletes were randomly assigned into two groups of plyometric exercises (n=10) and BFR group (n=10), for both groups the pre-test the Sargent Vertical jump test was used to measure the explosive power. Then plyometric training program for two groups, including six weeks of practice, each week two sessions selected but in one of the groups before exercise, vascular obstruction was performed in the thigh area by closing an elastic cuff around the thigh muscle in the proximal portion of both legs and a pressure of 120mmHg was used. After the completion of the six weeks protocol and the intervention both the group’s subjects were assessed to compare the groups covariance analysis was used (α<0.05). All computations were performed using SPSS software version 19. The comparing of the results of the training process of the experimental group in pre-test and after the post-test showed there was not a statistically significant difference in vertical jump of group that they did plyometric training with blood flow restriction. Neural adaptations such as increased activation and synchronization of motor units have been regarded as important factors for improving maximal power outputfor.
