Abstract:

Background/Objectives: The obesity for growing adolescents is not only an inducing factor to cause various adult diseases, but also is an obstruction factor to prevent the growth. Many studies verified that the exercise is the clearest, safest, and healthiest method in controlling the obesity. This study implemented dumbbell exercise for 10 weeks subjecting on 11 obesity male middle school students in order to define the effect of resistance exercise on appetite control related hormones, lipolysis related factors, and body components. Methods/Statistical analysis: A dumbbell treatment exercise was conducted for 11 obesity male middle students participating in the health care program. Appetite control hormone (leptin, ghrelin), lipolysis factors (GH, insulin, cortisol), and body composition (%fat, muscle mass) were measured and analyzed during 10 weeks of dumbbell treatment exercise. All data were verified through error-test to maintain the accuracy of data analysis, and the difference in the average values of the relevant variables between and within the group was t-tested. Findings:  After participating to dumbbell exercise, of body composition, muscle mass and %fat showed significant change, leptin and ghrelin levels of appetite control related hormones showed significant change, and growth hormone, cortisol, and insulin levels of lipolysis related factors showed significant change, respectively. Considering such results, dumbbell exercise increases muscle mass while influences a positive effect on appetite control and lipolysis to improve the obesity Improvements/Applications: In conclusion, resistance exercise of dumbbell exercise can easily control the exercise intensity and because of relatively easy delivery and low price, it can be a useful means as an exercise tool for maintaining and improving the health of obesity or physically weak people.
