최대운동수행으로 유도된 근통증이 점프 착지 동작에서의 하지 근육 활성도와 무릎 및 발목 각도에 미치는 영향 (The Effects of Maximal Muscle Contraction Exercise Induced Muscle Soreness on Lower Extremities Muscle Activities, Angles of Knee And Ankle in Drop Landing)

초록

The purpose of this study was to investigate the effects of maximal muscle contraction exercise induced muscle soreness on lower extremities muscle activities, angles of knee and ankle in drop landing. Six healthy recreational volleyball player participated in the study. Three trials of Intermittent maximal muscle contraction exercise was performed on a bicycle ergometer for 30 sec. The rest interval between maximal contraction exercise was 3 min. EMG signals of lower extremities were recorded during drop landing before and after maximal muscle contraction exercise and we also collected the data of angles of knee and ankle in drop landing. Statistical analysis of the findings of this study showed that maximal muscle contraction exercise induced muscle soreness caused significant increase in the muscle EMG of the lower extremities muscle when performing the drop landing. Also muscle soreness played roll in increasing the angle of knee and ankle in drop landing.
In conclusion, this study showed that maximal exercise induced muscle soreness increased the lower extremity muscle recruitment and angles of knee and ankle in dominant leg to keep the body stabilizing and position. Muscle soreness may increase the risk for musculoskeletal injury during rapid perturbations (as occurs in most sport activities) and therefore, exercise programs for patients and athletes should be carefully monitored for signs of muscle soreness after exercise and training to avoid deficits that might compromise dynamic joint stability.
