The purpose of this study is to verify a correlation between flexi-bar exercise and improvement of trunk strength and body composition in juvenile soccer players. The subjects were 11 teenager juvenile soccer players who conducted flexi-bar exercise half an hour daily three times a week for eight weeks. They were tested for trunk muscles strength, body composition and correlation. The result showed that trunk muscles strength improved significantly(p<.01) and weight, Rt. arm muscle mass, Rt. leg muscle mass, and Lt. leg muscle mass(p<.05), Lt. arm muscle mass, trunk muscle mass, and body muscle mass(p<.01) improved significantly as well while Lt. arm fat mass, Rt. leg fat mass, and Lt. leg fat mass decreased significantly(p<.05). In the correlation analysis, the more trunk muscle mass and trunk muscles strength increased, the more muscle mass of body regions increased, which was a positive correlation whereas fat mass of body regions decreased, which was a negative correlation. It was verified that there was a correlation between flexi-bar exercise and improvement of trunk muscles strength and body composition for juvenile soccer players.
