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.
