| Summary: | 碩士 === 國立臺灣體育運動大學 === 體育研究所 === 99 === The purpose of the study is to discuss the influnece of rope skipping intervened in P.E on junior high school students’ physical fitness. The subjects were 63 seventh graders,divided into a male group and a female group, at Gukeng junior high school, who skipped rope twince a week for twevel weeks. They all took a pretest in physical fitness before training. The average high of 32 male students is 157.95±8.00CM and the average of weight is 52.52±14.54 KG; the average high of 31 female students is 154.89±5.34 CM and the average weight is 45.73±8.47 KG. With dependent t-test, The test data was used to check if there was any difference between the pretest and the posttest; the significant level was set at p< .05. After analyzing the data, the study concludes that there is a sigificant difference in male students in respect to Body Mass Index (BMI), flexibility (Modified Sit and Reach Test), explosive strength (standing long jump) and cardio-pulmonary enduce (800/1600 meters running). However, they did not have a sigificant difference in endurance of muscle (sit-ups), lower leg girth and the stretch of ankle joints. The female students have large differences in flexibility (Modified Sit and Reach test), cardio-pulmonary enduce (800/1600 meters running), and the girth of both lower legs. By the contrast, the differences in Body Mass Index (BMI), endurance of muscle (sit-ups), and the stretch of ankle joints are subtle.
