Abstract: The purpose of this study was to investigate the number of repetitions and the MEF of the Biceps brachii for the 3 sets of maximal repetitive barbell curls with 3intensity. The subjects which were selected as men in their 20s who had more than 2 years of resistance exercise experience. The subjects also conducted a bar-cull experiment at each 7-day interval with a randoml assignment (50%1RM, 70%1RM, 90%1RM). In every one of the sets, the number of repetitions and the MEF of the Biceps brachii were measured. The measured two-way ANOVA was used, and the statistical significance was noted at the result of a = .05. The higher the intensity condition, the fewer the number of repetitions performed by the subject. The decrease of the number of repetitions was larger with a lower intensity condition. The lower the intensity, the higher the level of muscle fatigue was noted in the subject. In conclusion, it seems that the maximum repetitive exercise is seen to increase the muscle fatigue as the intensity is lower in those instances. Therefore, it is necessary to write a program considering the degree of muscle fatigue at low intensity in resistance exercise for the best results during an exercise program.
