背景與目的：現代人生活節奏忙碌緊湊，間歇性的運動方式因時問較具彈性，比較容易實行。本實驗希望能比較連續與間歇的兩種運動方式於運動期和恢復期耗氧量是否有所差異。方法：徵求18至29歲且身體健康的自願者，進行兩項跑步機行走測試，以間接量熱計(metabolic cart, SensorModics, V(下標 max)29)測量在跑步機上行走及休息時的能量消耗。步驟為（一）使用Bruce運動測驗，測試直到85%年齡預估之最大心跳率為止；（二）受試者於無坡度的跑步機上以106.6m/min的速度行走，隨機進行連續性（行走30分鐘後，坐在椅子上休息30分鐘）和間歇性行走（行走三次，每次行走10分鐘後皆坐在椅子上休息10分鐘）。以相依樣本t檢定(Paired-test)比較連續及間歇性運動之差異，實驗結果以SPSS/PC 10.0軟體進行分析。結果：本實驗共有19位自願者（男性10人，女性9人，平均年齡236±2.3歲）完成所有測試，本實驗之跑步機行走為輕至中度的活動，運動強度平均在51.5±10.7%VO(下標 2max)。間接量熱計的結果顯示，累計相同運動和休息時間的耗氧量，間歇性運動顯著高於連續性運動(t=-4.34, P<0.0005)；累計相同時間的運動期耗氧量，連續性運動顯著高於間歇性運動(t=4.15, P=0.001)；而在運動後的恢復期耗氧量，間歇性運動顯著高於連續性運動(t＝-12.01, P<0.0005)。結論：在強度固定並累積相同運動時間的情形下，間歇性運動可以較連續的運動累積更多的耗氧量，其耗氧量的增加主要是發生在運動後恢復期。而連續性運動可以在運動期間累計較多的耗氧量及能量消耗。不同需求的運動者可以選擇適合自己的運動方式，而對於其他的運動效益，或是在不同的年齡層，連續與間歇性的運動是否能達到相同效果，則須更多的研究探討。

Purpose: The purpose of this study was to compare the oxygen consumption during continuous and intermittent treadmill walking. Methods: Nineteen young and apparently healthy subjects were recruited to participate in this study. Indirect calorimetry (SensorMedics, V(subscript max)29) was used to measure the oxygen consumption during treadmill test. All subjects randomly participated in continuous treadmill walking (106.4 m/min, 30-minute exercise followed by 30-minute rest) and intermittent treadmill walking (106.4 m/min, 10-minute exercise followed by 10-minute rest and repeated 3 times) Paired t-test was used to compare the difference between continuous and intermittent exercise. Results: The mean age of subjects is 23.6±2.3 years. The average exercise intensity is 51.5±10.7% VO(subscript 2max). There is significant difference in total oxygen consumption between continuous and intermittent exercise (t=-4.34, p<0.0005). There is significant difference in exercise oxygen consumption between continuous and intermittent exercise (t=4.15, p=0.0l). And there is also significant difference in post exercise oxygen consumption between continuous and intermittent exercise (t=-12.01, p<0.0005). Conclusions: Intermittent exercise could generate more total and post-exercise oxygen consumption than continuous exercise. However, continuous exercise generates more oxygen consumption during exercise period than intermittent exercise.
