The purpose of this study was to investigate a difference of anaerobic capacity according to lower body’s muscle balance in university male. Subject were participated 78 university male student without medicine symptom of lower’s muscle. We established cross-sectional study and that independent variable was L/R muscle balance of lower body and quadriceps/ hamstring ratio. Results as follows; first, Anaerobic capacity showed that peak power and time to peak were highest power on L/R(100∼150%) in angular velocity(60°/s). But, fatigue index and mean power were highest power on L/R(75∼90%). Second, Anaerobic capacity showed that peak power and time to peak were highest power on L/R(90∼100%) in angular velocity(240°/s). And fatigue index and peak power were highest power on L/R(100∼150%). Third, Anaerobic capacity showed that fatigue index and time to peak were highest power on Q/H(80∼140%) in angular velocity(60°/s). And, peak power index and mean power were highest power on Q/H(158∼240%). Forth, Anaerobic capacity showed that fatigue index and time to peak were highest power on Q/H(78∼86%) in angular velocity(240°/s). And, peak power and mean power were highest power on Q/H(86∼96%). Viewed in this results, we think that there was no effect on lower body power according to L/R muscle ratio, and difference between extensor and flexor muscle strength was a lot of difference on exercise type and subject as well. In addition, we suggest that low angular velocity exercise should develop a quadriceps ratio and high angular velocity should be develop a equivalent between H/Q. Further study is good for suggesting to develop a muscle and injury prevention if we will investigate a frequently injury and muscle strength from muscle imbalance.

현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
