The effects of stepping exercise on body composition and blood lipids of female obese students

Students are increasing their obesity rates due to decreased physical activity and increased instant food intake due to study. The purpose of this study is to investigate the effect of stepping exercise on body composition and blood lipid in order to find a way to participate at any time with pleasant music.

In this study, 16 obese middle school students with body fat percentage of over 30% were divided into 8 stepping group and 8 control group. The stepping exercise group participated in the exercise for 1 week 45 minutes and 5 times a week for 10 weeks. The control group continued their daily lives without participating in any specific exercise program. All data measured in this study were averaged and standard deviations were calculated for all variables using the SPSS win12.0 statistical program. The difference test before and after intervention was compared by T-test. The difference between groups was analyzed using repeated measures analysis. The statistical significance was p<.05.

After 10 weeks of exercise, fat free mass was significantly increased in the exercise group(p<.01). Body weight and % body fat were significantly decreased(p<.01) as the exercise duration was longer, and also significantly(p<.05) between groups. Changes in blood lipids significantly decreased total cholesterol(TC), triglyceride(TG) and low density lipoprotein cholesterol(LDL-C) in the exercise group(p<.01). High density lipoprotein cholesterol(HDL-C) increased significantly after exercise(p<.01), and differences between exercise groups(p<.05) also appeared.

The results of this study showed that changes in body composition and blood lipids that were not observed after 5 weeks of exercise were changed after 10 weeks of exercise. However, it suggests that students should also change their dietary habits with exercise to achieve complete obesity.
