Subjects were randomly divided into two groups: aerobic exercise (EX) and control. The exercise program in EX group consisted of 90 minutes of aerobic exercise and running on a treadmill for 15.18±5.63 minutes, 4 sessions a week for 16 weeks with an intensity of 7 MET. Before and after the intervention, blood samples were collected to measure serum adropin, fasting insulin and glucose. Paired sample t test and independent t test were used to analyze data. BMI, WHR and HOMA-IR showed a significant reduction in EX group compared with the control group. Serum adropin levels increased significantly in EX group compared with the control group. A significant correlation were observed between changes of adropin and changes of BMI, WHR and HOMA-IR (<em>P</em><0.05). According to the relationship between adropin and insulin resistance and their susceptibility to aerobic exercise, adropin may play a special role in weight control and prevention of type 2 diabetes.
