本研究計劃將針對下肢運動中不同性別與年齡之使用者的心肺功能來研究分析，依照預測之最大心跳量，進行六週的運動訓練之後的生理變化，進一步分析此兩種運動處方在不同性別的成效差異，並且希望能夠透過這個研究結果，提供不同消費者未來運動需求時的參考依據，也期望可以提供運動器材產品設計師在設計運動處方時的一個方向。本研究結果顯示透過本實驗結果之橢圓機與自行車之心跳速率與攝氧量、體重的關係圖，研究結果顯示腳踏車與橢圓機的運動軌跡不僅接近，其在最大心跳等心肺功能生理反應上亦是接近，另外在高負荷附載運動下，橢圓機運動在心肺負擔下遠大於腳踏車，女性的生理反應上更是明顯，因此；若是以腳踏車的運動處方轉移到橢圓機上面，則須考量荷重負載增加的斜率，過大將會增加使用者的負擔，並且產生危險。所以本研究可將研究中設定之運動處方給予程式化，作為未來下肢橢圓運動模式程式設計時之參考依據。

This study aims to analyze the cardiopulmonary function of users of different sexes and ages in lower extremity exercise. Physiological changes after exercise training for six weeks according to the predicted maximum heart rate are further analyzed. And hopes to provide a reference basis for different consumers' future exercise needs through this research result. It also hopes to provide a direction for sports equipment product designers when designing exercise prescriptions. The results of this study: Through the experimental results of the elliptical machine and bicycle heart rate and oxygen uptake, body weight of the relationship between the results showed that bicycle and elliptical machine trajectory is not only close to its maximum heart rate and other cardiopulmonary physiological response Is close to the other in the high load with the movement, the elliptical movement in the cardiopulmonary burden is much larger than the bicycle, the physiological response of women is more obvious; therefore, if the bicycle movement prescription transferred to the elliptical machine, you have to consider the load Increased slope, too large will increase the user's burden, and dangerous. Therefore, in this study, we can formulate the exercise prescription set in the study as a reference for formulating the lower extremity elliptical motion model in the future.
