Abstract

Purpose: To investigate the effects of an 8 weeks of plyometric training on the total work of knee and ankles Joint. Methods: Nine university man aged 20$\~$22 years was divided in 2 group. Exercisers (N=5) performing plyometrics (pike jump, double leg hop, double leg bound, single leg hop, stride jump cross over, alternate leg bound, box jump) for 8 weeks. Controls (N=4) maintained their usual activities. The total work of knee and ankle joint were tested prior to and after the training. Results: Plyometric training resulted in significantly greater in the total work of high speed of knee and ankle motion(p<0.05). Conclusions: The plyometric training were partially improved the total work of flexion and extension on the ankle joint. Also plyometric training could influence athletic performance.

목적: 플라이오메트릭 훈련이 하지 슬관절의 굴곡과신전, 족관절의 배측굴곡과 족저굴곡의 등속성 총일량에 미치는 영향의 정도를알아보며이훈련법의효과검증을위해시도되었다. 대상및방법: 선택된 플라이오메트릭훈련 방식은 7가지로pike jump, double leg hop, double leg bound, single leg hop, stride jump cross over, alternate leg bound, box jump로구성되었다. 연구대상자는20 $\~$22세사이의대학생으로, 훈련시행군(N=5), 대조군(N=4)으로8주간 시행하고 훈련 전후 등속성 장비를 이용하여 슬관절과 족관절의 등속성 총일량을 측정하였다. 결과: 플라이오메트릭 훈련을 시행한군에서 높은 각속도의 슬관절과 족관절 운동의 총일량이 대조군에 비하여 증가하였다(p<0.05) .결론: 결과적으로 플라이오메트릭 훈련은 하지슬관절과족관절의등속성 총일량에 부분적으로영향을미치는것을알수있으며, 더나아가운동수행에도영향을미칠수있는것을의미한다.
