Abstract

The purpose of this study was to investigate the effects on body composition, blood lipids, and growth hormone by conducting Ju-do training after school for 8 weeks in overweight female middle school students. According to the research results, the conclusions are as follows. First, In the change in body composition, the weight and body fat percentage of the exercise group significantly decreased after 8 weeks of Ju-do training, and the muscle mass increased significantly. In the control group, there were no significant differences in body weight, body fat percentage, and muscle mass. Second, the total cholesterol, low density lipoprotein cholesterol, and triglyceride of the exercise group significantly decreased after 8 weeks of Ju-do training in the change of blood lipids, and high density lipoprotein cholesterol increased significantly. In the control group, there were no significant differences in total cholesterol, triglyceride, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol. Third, the growth hormone and IGF-1 of the exercise group increased significantly after 8 weeks of Ju-do training in the change of growth hormone and IGF-1. In the control group, there was no significant difference in both growth hormone and IGF-1. Summarizing the above, after-school Ju-do training was found to have a positive effect on obesity treatment, prevention of cardiovascular disease, and growth in overweight female junior high school students. It is considered that there is a need to develop an interesting and flexible guided exercise program in the future to make a comparative analysis under various conditions in consideration of daily activities such as physical activity, eating habits, and sleep time.
