진화은. 근육군 동원 형태와 운동강도에 따른 혈중 피로요소의 변화. 운동과학, 제15권 제4. 319-328, 2006. 본 연구의 목적은 상체, 하체, 전신의 각기 다른 근육을 사용하여 서로 다른 강도에서 운동할 때 축적되는 피로 요소들의 변화정도를 정량화시켜 근육동원 정도와 피로요소의 축적관계를 규명하고, 운동형태나 강도에 따른 피로요소의 축적 정도를 예측하는데 필요한 과학적 자료를 정립하는데 있다. 연구의 대상자는 7명으로, 암 에르고미터와 사이클 에르고미터를 이용하여 최대산소섭취량, 최대 절대강도, 중 절대강도, 약 절대강도로 팔, 다리, 팔과 다리 복합 운동에 3일 간격으로 참가하였다. 본 연구에서는 근육동원과 운동강도에 따라 각 피로물질의 변화가 각기 다른 유형을 보였으며, 각 피로물질들은 운동강도에 따라, 동원되는 근육량에 따라, 또는 이 두 가지 모두에 따라서 그 피로요소의 특징이 다르게 나타난다는 사실을 발견했다. 그러나, 운동시 축적되는 피로물질들의 대사적 기전은 다양하고 복잡한 생리학적 반응들이 복합적으로 연관되어 있으므로, 보다 과학적인 측면에서 근육량을 정량화시켜 근육동원 정도와 피로요소 축적과의 관계를 규명하는 연구가 계속되어야 하며, 더 나아가 이러한 것을 기본으로 하여 피로요소의 축적정도를 예측할 수 있는 자료를 정립할 수 있으리라 사료된다.
Abstract
Jin, H.E. Effects of changes in blood fatigue induction factors following different muscle group recruitment exercise. Exercise Science. 15(4): 319-328, 2006. The purpose of this study is to examine the changes in blood fatigue induction factors when the different muscles of upper body(A), lower body(L) and whole body(AL) were used in different exercise intensities(. There were seven subjects, who participated in exercises which involved VO2max(V) and three absolute intensity exercise(supramax(S), medium(M), minimum(N)), using arm ergometer and cycle ergometer. This study was examined every three days. The result of this study showed a different form of fatigue factors changes with different muscle mass recruitment and exercise intensities. The traits of the fatigue factors were found differently according to the exercise intensities, recruited muscle mass, or both of these. Moreover, the accumulation of fatigue factors depends on various and complex physiological reactions, the studies to examine the relation between the different level of muscle recruitment and corresponding fatigue factors change must be continued.
