The purpose of this study is to analyze the blood flow velocity of the artery and its effect on leptin and insulin. In order to carry out this study, 11 experimental and 10 control groups were classified. Obese children measured body fat rates using Inbody 3.0, measured blood relationship variables using Ultrasound Doppler, and analyzed leptin and insulin hormones. For blood relationship variables, the maximal blood flow rate of the subclavian artery in the experimental group and in the control group was not statistically significant; the mean blood flow rate was a significant reduction rate of –12.6% for the experimental group, but no change in the control group. Leptin was significantly reduced by –56.4% for the experimental group, with the control group having no significant difference. In the case of insulin, the experimental group had a significantly higher reduction rate of –79.0%, and the control group had no significant difference. In summary, the decrease of leptin and insulin hormones linked to the decrease in the average blood flow rate and body fat rate of the obese child was able to observe changes in blood flow rate, leptin and insulin sensitivity adapted to long-term circulation movements. Therefore, the cyclical motion program presented in this study is judged to have had an effective effect on the functional improvement of blood relations and the change of leptin and insulin, and is presented as an efficient aerobic exercise program for the adjustment of body fat in obese children, cardiovascular function and metabolic hormones in the future.
