Resistance exercise has been one of the major potent stimulus to the neuromuscular system. Based on the specific program design, resistance training has been reported to enhance strength, power, or local muscular endurance. However, the scientific basis of the exercise intensity has not been enough to manifest about several hormone(e.g. anabolic, catabolic or appetite hormone). So, the purpose of this study was to define that the responses of anabolic, catabolic and appetite hormone after resistance exercise of high level intensity(HI), moderate level intensity(MI), and low level intensity(LI). The subjects for this study were 9 men (Age=25.4±3.56yrs.; height=175.6±4.46cm; weight=71.6±8.97kg) who didn't have history of cardiopulmonary diseases and medical problems. They performed the circuit resistance training using HI(10reps at 80% of one-repetition maximum(1RM), 1min rest), MI(13reps at 60% of 1RM, 1min rest), and LI(20reps at 40% of 1RM, 1min rest) protocols with 3 sets. Approximately, total exercise volume was 39,000J on all of the exercise protocols. Hormonal concentration was measured at three different times: pre, post and recovery thirty minutes of the exercise. For the data, all of the measurements were represented by mean and standard deviation using SPSS statistical package(version 10.0). The statistical techniques for data analysis were two-way repeated ANOVA to determine the differences between each intensity and each time. One-way ANOVA was used to the specific analysis of exercise intensity. The 5% level of significance was used as the critical level for acceptance of hypotheses of the study. The results of this study were shown as followed; 1. The intensity of resistance exercise was not shown the differences in anabolic hormone(testosterone, IGF-1, growth hormone) and catabolic hormone(cortisol). However, anabolic hormone was significantly increased after all of the exercise protocols. On the other hands, cortisol was significantly decreased after the exercise protocols. 2. The catecholamine was increased in proportion to the resistance exercise intensity. Moreover, norepinephrine was significantly remarkably increased than epinephrine was. 3. Significantly, the lactate was increased in proportion to the resistance exercise intensity. Whereas, free fat acid was decreased after resistance exercise. 4. No differences in exercise intensity and time were observed in appetite hormone(leptin). Particularly, the trend was shown that leptin was decreased after resistance exercise on 40% and 80% of 1RM; whereas, leptin was increased on 60% of 1RM. In conclusion, the results of this study suggested that MI or LI resistance exercise training could contribute to safety more than HI resistance exercise could. In other words, relatively lower resistance of exercise intensity would decreased injury ratio, fatigue, and prevented to the excessive increment of blood pressure.
