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.
