Abstract:	本研究的目的在探討運動習慣在身體處於不同運動強度的情形下對能量來源消耗的影響。本研究徵召30名受試者年齡界於19-43歲，15位為有規律運動習慣組及15位為無規律運動習慣組。讓受試者穿戴可攜式無線遙測氣體分析測量儀(MetaMax 3B, Cortex)，在跑步機上以Bruce protocol運動模式運動直到其力竭為止，以擷取無氧閾值(anaerobic threshold, AT)前後的能量消耗相關的生理數值(AT前表低強度運動，AT後高強度運動)；而採用重複量數變異數分析來比較組別間和AT前後在呼吸交換率(RER)、脂肪、葡萄糖的消耗量、及總能量消耗的效應。結果顯示規律運動者的RER於AT前(0.72±0.12)明顯小於AT後(1.04±0.13) (P<0.05)，而無規律運動習慣者在AT前的RER明顯大於規律運動習慣者(P<0.05)。在AT前，規律運動習慣者利用脂肪，而無規律運動習慣者以葡萄糖為主要能量來源(P<0.001)；AT後，有、無規律運動習慣二者皆利用葡萄糖為主要能量來源(P<0.001 )；而有規律運動習慣者的AT後的總能量消耗明顯大於無規律運動習慣者(P<0.001 )。本研究建議有規律運動習慣者能在低強度運動狀態下主要燃燒脂肪，而無規律運動習慣者在高低強度運動也無法有效燃燒脂肪，因此，規律運動後可促進新陳代謝、提升體適能，並可改善能量來源的消耗情形。能量消耗;呼吸交換率;無氧閾值;規律運動習慣 The purpose of this study was to investigate the effects of regular exercise to energy consumption under different intensity exercises. Thirty subjects, range were recruited for this study, and 15 subjects with regular exercise were selected as the exercise group and 15 subjects with sedentary lifestyle were selected as the non-exercise group. Subject was asked to wear a mobile cardiopulmonary stress test system (MetaMax 3B, Cortex, Germany) and run on treadmill to exercise according to a Bruce protocol until volitional exhaustion. The physiological parameters were obtained including respiratory exchange ratio (RER), fat and glucose consumptions, and total energy consumption before and after anaerobic threshold (AT) (“before AT” represents a low intensity exercise, and “after AT” represents a high intensity exercise) in this study. A two-way repeated measures of ANOVA were used to test groups and before-after of AT effects on RER, fat and glucose consumptions, and total energy consumption. A level of statistical significance was p <0.05. Results showed the RER was significantly larger before AT (0.72±0.12) than after AT (1.04±0.13) (P<0.05). There were larger RERs before AT for non-exercise group than exercise group (P<0.05). Before AT, the fat for exercise group and the glucose for non-exercise group were the major sources of energy consumption (P<0.001). But after AT, the major energy source was glucose for both groups (P<0.001). And exercise group have larger total energy consumption than non-exercise (P<0.001). We suggested that person with regular exercise may be to consume the body fat in low-intensity endurance exercise, but sedentary lifestyle person was no efficiency to consume the fat during any intensity exercise in this study. Therefore, to form a regular exercise will contribute to the physical metabolism, promote the aerobic fitness, and improve the better situation in energy consumptions.
