The purpose of this study was to investigate the effects of aerobic exercise and resistance exercise on the body compositions and insulin, leptin responses. The subjects for this study were twenty-one obese female university students who participated in this experiment voluntarily and didn"t have any disease. The subjects were divided into three groups: control exercise group(N=7), resistive exercise group(N=7), and control group(N=7). The subjects in the exercise performed 60min in about, four times a week at the intensity of 60~80% HRmax. The subjects in resistive exercise performed three circuits using a work-to-rest ratio of 30s : 30s three times a week on non-consecutive days at 40% of one-repetition maximum. Statistical techniques for data analysis were One-way ANOVA training times(pre, 12 weeks) and repeated measure ANOVA to determine the differences among groups. The 5% level of significance was utilized as the critical level for acceptance of hypotheses for the study. The following results were obtained from this study. Aerobic exercise resulted in significant improvements in body compositions. Lean body mass increased after training in the both groups. The insulin and leptin improved after aerobic exercise, while the insulin and leptin decreased after resistive exercise without any changes of body weight, % body fat.
