The purpose of this study was to investigate the effects of 12 weeks jump rope exercise on plasma lipids and ghrelin in obese children. The twenty four elementary school children (% body fat higher than 30%) were volunteered for this study. They were randomly devided into jump rope exercise group (EXE n=12) and control group (CON n=12). The protocol of jump rope skipping exercise was 1000-3000 repetitions/5 days/12 weeks. The repetitions of jump rope were progressively increased for whole training period. Measured variables were body weight, VO2max, % body fat, ghrelin, TC, TG, HDL-C, LDL-C. Each of the measured data was calculated by Mean±SD, and processed statistically through the repeated two-way ANOVA (α<.05). Results of this study were as follows, body weight and % body fat of the EXE were significantly decreased after 12 weeks aerobic exercise. Ghrelin and HDL-cholesterol of the EXE were significantly increased after 12 weeks jump rope exercise. However, blood lipids which were plasma total cholesterol, LDL-cholesterol, and triglycerides were not changed after 12-week training. In conclusion, the results of this study suggested that 12-weeks jump rope exercise significantly affected both % body fat and ghrelin, but not blood lipids except for HDL-cholesterol in obese elementary children. Therefore, ghrelin increase in response to overweight reduction from an exercise intervention in obese children.
