12주간의 플라이오메트릭 트레이닝이 태권도 자유품새 선수의 순발력, 민첩성, 등속성 하지 근기능에 미치는 영향

초록

This study aims to determine the effect of 12 weeks of plyometric training on the explosive power, agility, and isokinetic lower limb muscle function of Taekwondo free-poomsae players. The subjects of this study were 40 college Taekwondo free poomsae players, and we randomly divided them into a plyometric training group (experimental group, 20 people) and a general free poomsae training group (control group, 20 people). All subjects measured explosive power, agility, and isokinetic lower limb muscle function before and after 12 weeks of training. As a result of the study, 12 weeks of plyometric training significantly improved the vertical jump (explosive power) and whole-body reaction speed (agility) of Taekwondo free poomsae players. In addition, the players' isokinetic (angular velocity 60°/sec) lower extremity muscle strength improved, and isokinetic (angular velocity 180°/sec) lower extremity muscle power significantly enhanced. Additionally, isokinetic (angular velocity 240°/sec) lower limb muscular endurance was improved. Overall, 12 weeks of plyometric training was confirmed to be effective in improving the explosive power, agility, isokinetic strength, muscle power, and muscular endurance of Taekwondo free poomsae players.
