摘要

聽自己喜歡的音樂不但可以使心情愉悅，也可以使人在忙碌之餘，能夠使心靈沉澱並解除心裡的壓力。以往的研究指出，音樂會影響到人類之自主神經系統，在壓力下聆聽音樂，可以降低血壓以及心跳率。所以在運動時聽音樂，不只可以使在運動過程中不無聊，或許也可以拉長運動的時間，並增加運動的效率。所以，本研究的主要目的是探討騎固定式腳踏車運動，在音樂的介入下，對於兩種運動模式-漸進式運動以及固定時間強度之運動，對於心肺功能以及心率變異之影響。本研究中包含12位受試者，皆沒有心肺功能的疾病。測試過程中，受試者皆配戴心率錶、心率變異量測模組及氣體分析儀，監測紀錄運動過程中心肺生理指數。受試者分四次測試有無音樂對於不同運動模式(漸進式及固定時間強度之運動)時，受試者運動時心肺表現的影響。實驗結果顯示，運動時有音樂的介入，心肺功能之參數都有上升的趨勢，尤其是心跳率上升達顯著性統計意義。自覺吃力指數在此兩種運動模式中，有音樂的介入都會使自覺吃力指數下降達顯著性統計意義，而運動持續時間雖然沒有顯著的增加，但都有延長的趨勢。漸進式運動中，在最大阻力0%、25%、50%、75%和100%時，有音樂的介入，其心肺功能在各階段則是都為上升的趨勢；而在固定時間及強度的運動中，在運動後第一分鐘、第十分鐘大部分都會比沒有音樂的時候來的高，但到第五分鐘、第十五分鐘則心肺功能之參數就會稍微低於沒有聽音樂的狀態下。在運動後立即恢復期，連續五分鐘，有音樂介入在這兩種運動模式中，心肺功能參數都有上升的現象。心率變異在休息時候有音樂的介入，低頻(LF)以及高低頻功率(LF/HF)比都有些微的上升，而高頻(HF)則有稍稍的下降，表示在休息時聽音樂是可以活化交感神經系統；漸進式運動立即恢復之心率變異，發現在低頻、高頻以及低高頻功率比都有下降的趨勢；固定時間強度的運動立即恢復之心率變異則是在低頻以及高低頻功率比有下降的現象，而高頻有上升的現象，也就表示音樂介入固定時間強度之運動後恢復，可使副交感神經較活化。所以，在音樂的介入下，無論是漸進式運動或是固定時間強度之運動，對於運動者都會有一激勵促進的效果，進而達到運動時間可以較持續，且可延長疲累感覺的產生。

Listensing the music that people like not only makes them feel delighted, but helps them releasing the pressure from heavy works. Previous literatures showed that music can affect human automatic nervous system, and under a certain pressure helps decresase blood pressure and heart rate. Nevertheless, listening to music when exercise not only keep people feel amused but it may also increase exercise duration and enhance the exercise performance. Therefore, the purpose of this research was to discuss the effect of music in cardiopulmonary system and HRV during progressive exercise and endurance exercise in cycling. Twelve subjects without any cardiopulmonary system syndrom recruited in this study. The effect of music in different exercise modes including progressive exercise and endurance exercise in cycling were tested in different four times. The heart rate detector, air flow detector and heart rate variability detector were attached on the subjects to record the cardiopulmonary parameters during exercise. The results showed that the intervention of music when people doing the cycling exercises shows differeces in cardiopulmonary parameters, especially the rise of heart rate and reduced RPE reached significantly differences. Though there is no significant increase in exercise duration, it still showed the extended tendency. No matter the resistance in 0%、25%、50%、75% and 100% of maximum resistance in progressive exercise, the intervention of music shows increase in every stage of cardiopulmonary parameter. However, during the endurance exercise, in the fifth minute and the fifteenth minute, the cardiopulmonary parameters were slightly lower than those in without music effect. In heart rate variability, there is slightly rise in LF and LF/HF when music appears in the rest while there is a slightly fall in HF which shows listening to music when having a rest can activate sympathetic system. There is a fall tendency in LF, HF and LF/HF in immediate recovery after exercise of progessive exercise. There shows a fall in LF and LF/HF while a rise in HF in immediate recovery after exercise of endurance exercise which indicates the intervention of music in immediate recovery after exercise of endurance exercise can activate parasympathetic system.
