有氧運動對過重或肥胖者食慾及食慾荷爾蒙之影響
Effects of aerobic exercise on appetite and appetite hormones in individuals with overweight or obesity
摘要
生活方式的改變造成現代人長期能量失衡，進而對身體組成和代謝功能產生負面的影響。肥胖者除了增加罹患慢性疾病的風險及死亡率外，食慾荷爾蒙敏感性也會下降。先前文獻顯示，長期的身體活動可以預防或改善肥胖問題。標準體重者完成強度為60% VO2max以上的單次有氧運動時會暫時抑制食慾。然而肥胖或過重者執行同樣強度有氧運動的反應尚無一致的結果。故本研究以文獻回顧的方式探討肥胖或過重者進行單次或長期有氧運動對食慾和食慾荷爾蒙之影響。研究結果經文獻搜尋和整理可得出以下論點：一、單次中等強度有氧運動介入後肥胖者食慾會上升；二、單次高強度間歇運動可以抑制肥胖者食慾；三、長期有氧訓練有提升肥胖者食慾荷爾蒙敏感性的趨勢；四、肥胖者空腹狀態或運動後的食慾荷爾蒙反應，未來仍需更多研究加以探討以闡明其生理機轉。

Changed lifestyle nowadays had caused people long-term energy imbalance, which has negative impact on body composition and metabolic function. Besides high risk of developing chronic diseases and increasing mortality, the sensitivity of appetite in obese individuals is also decreased. Studies showed that regular physical activity can prevent or improve obesity problem. Recent evidence indicated individuals with normal weight performing aerobic exercise at or greater than 60% VO_(2max) would suppress appetite transiently, yet overweight or obese individuals did not show the same results. The purpose of this review is to investigate the effect of single bout and long-term aerobic exercise on appetite and appetite hormones in obese or overweight individuals. After analyzing and searching studies, we summarized the following conclusions: 1.The appetite would increase after single bout of moderate aerobic exercise in obese individuals; 2.The appetite would suppress after single bout of high intensity interval exercise in obese individuals; 3.Long-term aerobic training had tendency to promote appetite sensitivity in obese individual ; 4.The response of appetite in obese individuals whether at fasting or postexercise status is still unclear, so as the mechanism which need further studies to examine.
