Kim, Tae-Young Advisor : Prof. Seo, Young-Hwan, Ph.D. Major in Physical Education Graduate School of Education Chosun University

This study is aimed at reveling how participating in after-school sports activities affects obese male middle school students in levels of fitness (muscle strength, muscle endurance, cardiovascular endurance, flexibility of the body, explosive muscular strength, agility) for 12 weeks. From this result, we carried out correspondence samples t-test for significant difference verification in exercise groups and independent t-test between groups. Level of significance was established with p<05. Then, we come to the following conclusion.

Weight and the body fat of exercise group was reduced, and muscle strength in body strength factor showed significant difference statistically.(p<.001). and cardiovascular endurance showed significant difference(p<.01). Also, increase of flexibility of the body showed significant difference statistically(p<.01). and decrease of explosive muscular strength showed significant difference statistically(p<.05). Increase of agility showed significant difference statistically(p<.001) While muscle endurance was increased, there was not statistically significant difference. Before experiment, there was significant difference in muscle strength, muscle endurance, cardiovascular endurance, between groups.

It was summarized as follows that group participating in after-school basketball activities for 12 weeks showed decrease of the body fat(%) and increase of levels of fitness(muscle strength, cardiovascular endurance, flexibility of the body, explosive muscular strength, agility) However, it is considered that if more subjects of study and a long-range exercise program to get more definite answers are performed., this will be good basic data of diet program to obese middle school students and study of the comparative analysis through various measurement methods will be performed.
