This study aims to investigate how types of physical education class have effects on the body Composition(height, weight, body fat percentage), the Factors Relation to growth(growth plate, growth hormone; GH, insulin-like growth factor-1; IGF-I) of second grader boys in middle school to establish the direction of a new class model in school, and to make the best use of physical education class. The subjects of this study are healthy students who don't have any special exercise experiences or medical diseases based on medical checkup, whom I divided into three groups : individual exercise group of 12, collective exercise group of 12, and controlled group of 12. The exercise programs are done to each group : individual exercise group and collective exercise group for 45 minutes a day, three times a week, for 12 weeks. The data processing of this study is done by comparing the average and standard deviation of each group using SPSS version 19.0K statistical research program. The meaningful difference among the comparison of each group average is verified by analysis of covariance which is a measure of how much the preliminary examination feature and post examination feature change, and then by a way ANOVA about equal variance. The level of significance of every statistic is p<.05. The conclusion deducted by this research is as follows. First, in body Composition, the height of individual and collective groups increased more(p<.05) than that of the controlled group, body fat percentage decreased more(p<.011) in the individual and the collective groups, but increased a little in the controlled group. Weight didn't show the difference among the groups. Second, in the Factors Relation to growth, the width of growth plate decreased more(p<.001) in the collective and individual groups than in the controlled group, and the secretion rate of GH hormone and IGF-I hormone increased more(p<.001) in the collective and individual groups than in the controlled group. Putting all these results together, it can be possible for middle school boys in their growth period to make the best use of physical education class, and to improve their lives in body Composition the Factors Relation to growth, and mental health.
