The purpose of this study was to investigate effective practice program of training and to provide teaching-learning materials, and to compare and analyze amount of changing for physical fitness and 100m running. Twenty-four male children who did not go through training were selected in fifthe grade of N elemenraty school in Daegu. they were classified with three groups(8 children in each group, at fandom, -Circuit training group, Weight training group, Controlled group). All 10 weeks training, the records of physical fitness and 100m running was measured. For the study, I made use of One-way ANOVA, T-test, Repeated measure ANOVA, Pearson r and Multiple regression(p<.05) the results were summarized as the followings: 1. There was the significant difference in physical fitness and 100m record among circuit training group, weight training group and controlled group. 1) In the circuit training group, the power , agility and 100m record were improved. 2) In the weight training group, the strength, muscle endurance, power and 100m record were improved. 3) In the controlled group, the muscle endurance was decreased. 2.. There was the significant difference in 100m record between trained groups and controlled group. However, there was not the significant difference between the circuit training group and the weight training group even though the former was more improved than the latter. 3. In the interactie effects between the measured poing and each group, statistically significant difference represented on the strength, muscle endurance, power and 100m record. 4. In the correlation of physical fitness, training method and 100m recordm the strength and the power had significant influence on 100m record although the muscle endurance, power, agility were correlated to 100m record.
