Abstract
The purpose of this study was to investigate the effects of Kettlebell program on the physical composition, physical fitness, and pulmonary function in middle school soccer players. The subjects were 16 boys’ middle school soccer players, consisting of control group (n=8) and experimental group (n=8). The exercise program was conducted for 8 weeks, 3 times a week, and 60 minutes once. The 8 ㎏ kettlebell was used to gradually increase the number of sets and the number of sets every two weeks. The data analysis was performed using by 2-way (RM)ANOVA, and paired t-test. The results are as follows. Body composition has an interaction effect at the abdominal fat rate, and post-hoc has a significantly decreased in the exercise group(p＜.05), and fat free mass, body fat, body fat rates did not interaction effects. Physical fitness has an interaction effect at the agility, and post-hoc has a significantly decreased in the exercise group(p＜.05). and flexibility, grip strength, back strength, quickness, balance, drawing distance did not interaction effects. Pulmonary capacity has an interaction effect at the EVC1, and post-hoc has a significantly increased in the exercise group(p＜.05), and FEV1, MVV did not interaction effects. In conclusion, 8-week kettlebell training showed the positive effects on abdominal fat percentage, agility, EVC1 in middle school soccer players.
