방과후 축구활동이 남학생의신체능력에 미치는 영향

Abstract

The purpose of this study is to present the preliminary data for the development of school physical education and vitalization of sports for all by investigating the effect of 6-week soccer activity on physical ability in high school male students. Subjects(n=28) were divided into two groups: exercise group(E.G., n=14) and control group(C.G., n=14). The subjects in E.G. had played soccer 50 min./day, 3 times/week for 6 weeks. We measured BMI and physical ability(speed, flexibility, and muscle endurance) two times: pre event(0 week) and post event(6 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, Speed was significantly different between pre event and post event measurement(p<.001) in both of E.G. and C.G. Flexibility showed the significant difference between pre event and post event measurement(p<.001) only in E.G. Muscle endurance was significantly different between pre event and post event measurement(p<.05) only in E.G. In conclusion, we found that 6-week soccer activity increases physical ability and decreases BMI in high school male students. To get clearer data, however, further studies in which researchers compare and analyze studies with a lot more subjects and various measuring methods will be necessary.
