THE EFFECTS OF PLYOMETRIC TRAINING AND BLOOD FLOW RESTRICTION ON EXPLOSIVE POWER IN TAEKWONDO PLAYERS

The aim of this research was to investigate the effects of plyometric training with blood flow restriction on explosive power in Taekwondo players. Method: twenty taekwondo players who were volunteers to participate in the project, and the conditions of entry into the study (including 14–17 year old, at least 2 years in the provincial league and the minimum red belt, were selected into two groups of plyometric exercises (n=10) and BFR group (n=10), from both groups the pre-test for the variable study (vertical jump) then plyometric training program for the two groups, including six weeks of practice, each week two sessions, the time of each session was 45 to 60 minutes, except that in one of the groups before exercise, vascular obstruction was performed in the thigh area, obstruction of the vessels by closing an elastic cuff around the thigh muscle in the proximal portion of both legs was closed and a pressure of 120 mm Hg was used. The results of this study showed that plyometric training with vascular obstruction cannot has a significant effect on explosive power. In order to obtain better knowledge in this field, hormonal, neuromuscular and other mechanisms cell metabolites should be investigated.
