Light to heavy system과 Heavy to light system 저항운동이 Cortisol, IGF-1, Testosterone 및 주동근의 iEMG, MEF, 총운동량에 미치는 영향
Effect of LTH and HTL system on cortisol, IGF-1, Testosterone and agonist muscle iEMF, MEF, total momentum
The purpose of this investigation is that, the combination of resistance training exercise based on the way cortisol, IGF-1, testosterone and agonist of the iEMG, MEF changes, total momentum was to compare the effects. After the measurement of 1RM from 12 Physical Education Students in good health. Light to Heavy system and Heavy to Light system was conducted at random for them. Blood samples were collected throughout the pre and post. Result of the investment is that cortisol levels were higher in the LTH system, but IGF-1, testosterone, there was no significantly different. After the bench press, pectoralis major muscle, and triceps brachii’s iEMG were significantly higher in the LTH system. In the HTL system from a set of triceps brachii were significantly higher. The result of comparison about total momentum, the LTH system were significantly higher at 1st set, and the HTL system were higher at 2nd and 3rd set. In conclusion, the secretion of cortisol is depending on the degree of stress, in the case of IGF-1, the secretion is activated with low degree of stress. Started from a low-intensity momentum is more effective way.

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.
