摘要

本研究目的為探討短期高強度坐式腳踏車訓練對血管功能的影響，並瞭解短期高強度間歇訓練（high-intensity interval training, HIIT）前、中、後對血管功能的變化。招募健康大學男生隨機分派至HIIT組（n = 43）與控制（control, CON）組（n = 16），正式訓練前測得坐式腳踏車最高心跳率後，HIIT組進行2週內進行10天HIIT，每天以10次90%最高心跳率強度訓練1 min及間歇休息1 min，CON組則保持正常生活作息，兩組在訓練前、訓練中及訓練後分別檢測得手指－腳趾脈波傳導速率（finger-toe pulse wave velocity, ftPWV）、收縮壓、舒張壓及平均動脈壓。研究結果顯示：HIIT組在訓練後的ftPWV顯著低於訓練前與訓練中，HIIT組在訓練後ftPWV顯著低於CON組，但訓練後收縮壓、舒張壓及平均動脈壓沒有顯著影響。本研究結論：健康成年男性進行短期2週內進行10天的HIIT後在ftPWV會顯著下降，顯示能降低動脈硬化程度，進而改善血管功能。

The purpose of this study was to explore the effects of short-term high-intensity cycling exercise on vascular function, and to understand the changes in vascular function before, during and after short-term high-intensity interval training (HIIT). Fifty-nine healthy male students were recruited from the university, and randomly assigned into HIIT group (n = 43) and control (CON) group (n = 16). All participants in the HIIT group performed ten days of HIIT in two weeks, including 90% heart rate peak of cycling exercise and interspersed with 1 minute rest after the measurement of heart rate peak. During the experimental period, participants in the control group maintained their normal life. Finger-toe pulse wave velocity (ftPWV), systolic blood pressure, diastolic blood pressure, and mean arterial pressure were measured before, during and after short-term HIIT. Results indicated that ftPWV in HIIT group was significantly lower after exercise compared with before and during training. Post-training, ftPWV in HIIT group was also significantly lower than that of the CON group. However, there were no significant effects on systolic blood pressure, diastolic blood pressure and mean arterial pressure. Our findings conclude that two weeks HIIT can decrease ftPWV in healthy men. HIIT may improve vascular function, and thereby decrease the risk of arteriosclerosis.
