The purpose of this study was to chase the influence that increase of the number of class hours gave to the physical fitness improvement of the junior high student using longitudinal data for a long term. The program was held among approximately 338 junior high school students through all grades students who came from in asahi-shi of Chiba prefecture. In order to verify the effectiveness of this research, 8 different physical fitness tests, and the primary results were as indicated below.
Comparing between the first and the third grader, the third grader's physical fitness test total score shows twice than first graders. Moreover, a significant difference was witnessed through all these results (p<.05).
Comparing among the first and the third student's physical fitness tests, the evaluation was twice among them. As for boys, High evaluation increased, and low evaluation decreased.
The experimental group has been increased by physical fitness more than by the maturity. In the experimental group of the boy, it was effective by a physical fitness improvement program. Furthermore, a significant difference was witnessed through all these results (p<.05).
As for girls, a significant difference witnessed by the control group, and low evaluation decreased. Furthermore, the physical fitness total score of the experimental group increased in annual. There was no difference in the physical fitness test evaluation between first grader and third grader. There was an increase by the maturity. But the increase due to raised (maturity) did not indicate physical fitness test evaluation.
While in the control group was increased, low physical fitness test evaluation. As a result, this physical fitness improvement program, and the experimental group of the girl were able to restrain the down of the physical fitness.
