本研究之目的在於探討八週間斷性步行運動對學童健康體適能之影響。21 位參 與本研究之學童， 其平均年齡、 身高、體重分別為 10.05 ± 0.80 歲、 141.82 ± 7.04 公分、38.41 ± 10.03 公斤。 研究進行八週之間斷性步行介入運動，受試者自行挑選步行 之速度 (自覺舒適的速度 )，每週三天， 每天上、下午各一次，每次分別進行 10、15、20 分鐘的步行運動。 介入運動前後所獲得之體適能測驗資料，經分析後所得的結果如下：(一 ) 在三組中的柔軟度及心肺功能經訓練後有明顯地改善。(二 ) 每週至少三天，每天兩次持 續十五分鐘以上的時間進行步行運動，可促使改善或維持適當的心肺功能與柔軟度。

　　　　　The purpose of this study was to investigate the effects of intermittent walking on physical fitness of elementary school students. The average age、 height and weight of the 21 subjects were 10.05 ± 0.80 year-old、 141.82 ± 7.04 centimeters、 38.41 ± 10.03 kilograms, respectively. The intermittent walking intervention exercise was held for over eight weeks, three times every week, and each time for a duration of 10、 15、20 minutes at morning and afternoon. Tests were conducted before and after the intervention exercise, the results of the tests are as follows. 1.Among the three groups, flexibility and cardiorespiratory function have significantly improved throughout training. 2.Walking above three days per week, twice per day, fifteen minutes per time will improve or maintain appropriate flexibility and cardiorespiratory function.
