이심성 수축에 따른 혈중 피로 유발 요인들의 변화 형태가 운동 후 근육 손상의 지연 현상에 미치는 영향. 운동과학, 제13권 2호, 251-262, 2004. 본 연구의 목적은 일반 남자 대학생 10명을 대상으로 트레드밀을 이용하여 평지(level running; LR)와 내리막 경사 조건(decline running; DR)에서 자신이 선호하는 달리기 속도로 달리기 운동을 수행했을 경우, 혈중 피로 유발 요인들(젖산/암모니아/무기인산)의 변화 형태가 운동 후 혈중 근육 손상의 지표인 CK 활성의 지연 현상에 미치는 영향을 고찰하는데 그 목적이 있다. 실험 조건에 따른 산소소비량의 변화에 있어서는 DR에서 운동시 더 낮은 산소소비량을 보여 통계적으로 유의한 차이가 발견되었다(p<.05). 혈중 CK 활성 변화의 경우, 운동이 종료된 12시간 후, 24시간 후, 그리고 48 시간 후에 각각 DR에서 더 높은 혈중 CK 활성을 보여 통계적으로 유의한 차이가 나타났다(p<.05). 혈중 젖산 농도 변화에 있어서는 LR 조건이 이심성 수축 형태인 DR과 비교하여 운동 종료 시점에서 더 높은 농도를 보여 통계적으로 유의한 차이가 발견되었다(p<.05). 혈중 암모니아 농도 변화에 있어서는 이심성 수축 형태인 DR 운동 종료 시점에서 더 높은 농도를 보여 통계적으로 유의한 차이가 발견되었다(p<.05). 혈중 무기인산 농도 변화에 있어서는 이심성 수축의 형태인 DR과 LR 사이에 통계적으로 유의한 차이가 발견되지 않았다(p>.05). 결론적으로, 이심성 수축 형태가 주로 이루어지는 DR은 근육 손상의 간접적인 지표인 CK의 활성 증가 비율의 연장 현상이 유도되어, 운동 후 12-24 시간 사이에서최고치를 보여 평지 조건에서 보다 더 많은 근육 손상 유발 가능성을 내포하고 있다고 볼 수 있다. 또한, 운동시 생리학적 피로 유발 요인들 중 혈중 암모니아 농도의 경우 운동 후 근육 손상의 지연 현상과 가장 밀접한 관련이 있는 피로 요인으로서의 역할을 담당하고 있다고 본다.
Abstract
Effect of Blood fatigue factors following eccentric exercise on delayed muscle damage. Exercise Science, 13(2): 251-262, 2004. The purpose of this study was to examine the effect of blood fatigue factors following eccentric exercise on delayed muscle damage. The running tests were performed on a treadmill for 30 min and all subjects(n=10) of present study participated in two different kinds of experimental conditions.: one was level running(LR) and the others was downhill running(DR) at a decline angle -14 % with their favorable running speed.There were significant difference in the total VO2 between LR and DR conditions(p<.05). The mean blood CK activity of DR was higher than that of LR group at the 12 h, 24 h, and 48 h after finishing test, and there were significant difference between LR and DR conditions following the running exercise(p<.05). In the mean blood lactate concentration at the end of the 30 min running exercise, there were significant differences between LR and DR conditions(p<.05). In the mean blood ammonia concentration at the end of 30 min running exercise, there were significant differences between LR and DR conditions(p<.05). However, there were no significant differences in blood phosphorus concentration between LR and DR conditions at the end of 30 min running exercise(p>.05).In conclusion, an indirectly marker of muscle damage, serum CK activity was a significantly higher at the 12-24 h after downhill running in particular involves substantial eccentric exercise. Also, one of most effective blood fatigue factor on delayed muscle damage might be ammonia concentration and production during eccentric exercise.
