하지 중심의 플라이오메트릭 훈련과 등속성 훈련이 등속성 근력 및 점프수행능력에 미치는 영향

Abstract

The purpose of this study was to examine the effects of plyometric and Isokinetic training on muscle strength and jump performance. The subjects consisted of 15 adult males who are majoring Physical Education at the University. These were divided into three groups; plyometric training group, isokinetic training group, control group. The training group performed several movements based on each training method during 6 weeks. The isokinetic muscle strength was measured by Cybex 6000. Jump performance was measured by SJ height, CMJ height, and RJindex. Two way repeated ANOVA was used to analyze the interaction effect of group and time. Isokinetic training group showed strength elevation from more joint than that of plyometric training group. Plyometric training group and isokinetic training group showed similar improvement in SJ height, CMJ height, and RJindex statistically. In conclusion, the results of this study suggested that isokinetic training has an effect on the isokinetic muscle strength, and the jump performance ability Improvement of physical strength and functionality can be expected in accordance of the stability which is the a significant aspect of isokinetic training.
