The purpose of this study is to present the preliminary data for the positive change of body and maintenance of the health through investigating the effect of yoga exercise on BMI and the level of physical ability in obese middle school male students. Thirty subjects were divided into two groups: exercise group(E.G., n=15) and control group(C.G., n=15). The subjects in E.G. had done yoga 50 min./day, 3 times/week for 12 weeks. We measured BMI and physical ability(muscle endurance, cardiopulmonary endurance, flexibility, and speed) two times: pre event(0 week) and post event(12 week) measurement. For the data analysis, paired t test and independent t test of SPSS ver. 18.0 were used to analyze the change between pre event and post event measurement in each group and the difference between groups in each measurement, respectively. The significant level was α=.05. As a result, BMI was significantly different between pre event and post event measurement(p<.001) only in E.G. and between two groups at post event measurement(p<.001). Muscle endurance, flexibility, and speed showed the significant difference between pre event and post event measurement in E.G(p<.001). Cardiopulmonary endurance was significantly different between pre event and post event measurement(p<.001) only in E.G. and between two groups at post event measurement(p<.001). In summary, we confirmed that 12-week after-school yoga exercise decreases BMI and increases physical ability in obese middle school male students. To get clearer data, however, further studies in which compare and analyze studies with a lot more subjects and various measuring methods will be necessary.
