隨著運動知識的普及，愈來愈多人關心運動與健康。一般人都知道運動的好處與重要，但以何種強度進行運動，對身體健康的效果最好，一直是每一位運動者所關心的議題，因此必須建立足夠的資料來提供我們判斷多少的活動量才能獲得最佳的效果。本研究將針對橢圓機運動模式，設計兩種不同運動強度參數，比較不同性別在6週運動訓練後的生理變化，並分析此兩種運動處方在不同性別的成效差異。結果顯示，無論何種強度運動，女性組身體質量指數與體脂肪比例皆有明顯的降低，男性組則無。訓練前後的心肺耐力指數皆有明顯的進步，且女性組增進的幅度比男性大，中強度也較高強度組增進幅度大。高強度組之肌力與肌耐力皆有顯著的進步，進步幅度較中強度組顯著。

More and more people care about sports and health in the wake of the popularity of sports knowledge. Most people are aware of the benefits and importance of exercise, however, at what level of intensity when exercising is the best for physical health has been the subject of concern to all exercisers. Therefore, it is required to gather adequate information for us to determine how much exercise gets the best results. Targeting the elliptical trainer exercise pattern,this study designs two different exercise intensity parameters, compares physiological changes of different genders after six weeks of exercise training, and analyzes the efficiency differences between the two exercise prescriptions in different genders. The results show that, regardless of any level of exercise intensity, the body mass index and body fat percentage of the female group have reduced significantly, contrarily the male group has not. Both groups have significantly improved cardiorespiratory endurance index before and after training, and the female group’s improvement is bigger than that of the male group, and the intermediate -intensity group performs better than the high-intensity group as well. High-intensity group’s muscular strength and endurance have remarkably improved of which the scale is more prominent than the intermediate -intensity group’s.
