Abstract:	目的：比較腳踏車運動之前，接受呼吸肌熱身是否能提升運動表現。方法：本研究受試者對象為10名經常運動的學生（年齡：24.70±1.42歲；身高：174.10±3.51公分；體重：75.40±9.17公斤），每位受試者以平衡次序方式分別在原地腳踏車測功儀上以俯握姿勢進行漸增負荷測驗，在測驗前利用呼吸肌訓練器以快吸慢吐的方式進行呼吸肌熱身，因吸氣時透過呼吸肌訓練器的壓力閥會產生阻力，必須以快且強力的吸氣才能順利吸氣，讓呼吸肌在呼吸過程中增加呼吸肌的負荷，達到熱身的效果。有呼吸肌熱身與無呼吸肌熱身各進行一次漸增負荷運動測驗（每次實驗至少間隔24小時），分別觀察150W、200W與衰竭時的生理反應與運動表現。結果：測驗過程中所採集之各項生理變化中，發現換氣量、換氣頻率、攝氧量、心跳率與呼吸困難知覺皆無差異，運動時間也無明顯差異。結論：呼吸肌熱身後，並無法對腳踏車運動過程中各項生理反應與運動表現產生明顯的效果。 Purpose: The purpose of this study was to compare whether respiratory muscle warm-up can enhance performance in cycling. Methods: Ten activity males (age 24.70±1.42 yrs; height: 174.10±3.51 cm; weight: 75.40±9.17 kg) were recruited to participate the experiment. By counter-balanced design, all subjects used aero position to complete two incremental load tests with and without respiratory warm-up on different days. Warm up in fast inhaling and slow exhaling manner was employed for respiratory muscle by which training device increases valve pressure to induce resistance to the respiratory muscle when inhaling. During tests, we observed physiological responses at 150W, 200W, exhaustion and time to exhaustion as performance index. Results: There were no significant differences in V(superscript ‧) E, ventilation frequency, V(superscript ‧) O2, HR, perception of dyspnea and exhaustion time between 2 visits at 3 intensities. Conclusions: The expiratory muscle warm-up does not provide obvious effect on physiological responses and exhaustion time in cycling.
