To analyze the effects of 10-week combined training (aerobic and resistance exercise) in three groups that were divided according to the total exercise dose per week and elucidate its effects on lipid metabolism hormones (insulin

leptin

growth hormone) and stress hormones (ACTH

cortisol

). We included 24 obese male college students with body mass index ≥ 25 kg/m2. Each 8 subjects were randomly assigned according to the total exercise dose per week into the 150-

270-

and 450-min/wk exercise groups

which performed 50-

90-

and 90-min exercise per day for 3

3

and 5 times a week

respectively. To maintain a constant level of exercise intensity

aerobic exercises were performed while maintaining 60%–70% of the maximal heart rate and resistance exercise at 60%– 70% load of the initial 1 repetition maximum; 1 repetition maximum was measured every 2 weeks. Training effects on lipid metabolic regulatory hormones in the blood and metabolic syndrome index according to the total exercise dose/week were analyzed. Insulin and leptin showed a significant decrease in 270-

and 450-min/wk exercise groups

It had been proved to have the significantly difference among all the groups. But growth hormone did not change. ACTH

cortisol levels decreased in each group showed a downward trend. And the more exercise time group

the more obvious the downward trend

but there was no significant difference in the results.
