태권도 시범선수의 플라이오메트릭 트레이닝이 무산소성 파워와 등속성 근기능에 미치는 영향

Abstract

The purpose of this study was to investigate the effects of plyometric training on the anaerobic power and isokinetic muscular function in Taekwondo demonstration players. Fourteen male Taekwondo demonstrators were randomly divided into plyometric training group (PTG, n=7) and control group (CG, n=7). Exercise program performed for 60 min(warm-up 10 min, main exercise 40 min, cool down 10 min), three times a weeks. The anaerobic power and isokinetic muscular function measurements were performed and pre (0 week), post (8 weeks). Result showed that plyometric training program was significantly increased in anaerobic power (peak power, fatigue index) in post- test than in pre-test. Knee isokinetic muscular function 600/sec, peak torque %Body Weight (extension, flexion) was also significant increased after 8 weeks of plyometric training program. Also, knee isokinetic muscular function 1800/sec total work % Body Weight (extension, flexion) was significant increased post-test than in pre-test. After 8 weeks plyometric training increased anaerobic power and isokinetic muscular function. Thus, suggest that plyometric training can have a positive effect on the performance of taekwondo demonstration players.
