| Summary: | 碩士 === 國立屏東教育大學 === 體育學系 === 99 === The purpose of study was to investigate the effect of jump rope exercise during class recess on physical fitness of intermediate grade school students by accumulation way. The study participants were two classes of third grade elementary school students of Ming He Elementary School in Pingtung. I divided them into male and female two groups 20 persons in each group. One for training group and another for controlling group, each group has ten male and female students. The training group did rope skipping movement for three recesses a day(5-8 minutes per ret), five days a week among forty-weeks. The participants were measured body composition by Inbody 720 test, explosive power, muscular endurance, flexibility and cardiorespiratory endurance before and after training. To anglicize by independent one-way analysis of covariance whether there were the remarkable effects before and after training between two groups. The significance is .05 (α=.05). The result is that the cardiorespiratory endurance(294.0 vs.338.0 sec，p＜.05 ), flexibility(29.5 vs. 27.1 cm，p＜.05) and explosive power（162.4 vs. 149.3 cm，p＜.05） of the training group were obviously different from the controlling one after forty-week training, but the other items were not, like height, weight, BMI and body composition. The conclusion of the study is: Forty-week Jumping Rope Exercise Intervention on Physical Fitness of intermediate grade school students by accumulation way had improvement effect. So it is worthy to popularize in elementary schools and we expect our next generation has better physical fitness.
