The purpose of present study was to study the changes of steroid hormone, growth hormone and insulin concentration following aerobic exercise on body composition in obese children. The subjects of this study was divided into two groups; obese children group(n=10); non-obese children group(n=10). All subjects participated in maximal exercise test to calculate their 65% HR max workload, and also they were measured body composition and blood samples were drawn from antecubital vein before taking part in exercise training programs and at 4 and 8 weeks post. There was significant different in the body weight and % body fat between obese children group and non-obese group(p<.05). However, there was no significant different in the fat free mass between obese children group and non-obese group(p>.05). There was significant different in the blood cortisol, testosterone, growth hormone and insulin concentration between obese children group and non-obese group(p<.05). In conclusion, aerobic exercise training for 8 weeks could be caused the decrease of % body fat and the increase of insulin sensitivity. In addition, the changes of testosterone and cortisol with insulin had positive metabolic effects of body composition to obese and non-obese children.
