背景及目的：在不同運動模式下，運動後過攝氧量會有所差異，本實驗嘗試以另一種定量運動強度之方式，探討在相同心跳率的運動強度下，有氧運動與重量訓練對運動後過攝氧量之差異。方法：十四位自願參與之女大學生，利用可攜式氣體分析儀對有氧運動與重量訓練下的每次呼吸氣體交換進行連續監測，有氧運動採取固定式腳踏車運動，維持在70%最大心跳率持續25分鐘，重量訓練以3項測試項目（大腿伸張、腿部屈曲、高滑輪下拉）輪流進行10次(10RM)反覆重量訓練，運動組數以受試者達到70%最大心跳率為止。結果：重量訓練之運動後過攝氧量最大值與有氧訓練測試間無顯著差異，然而運動後過攝氧量持續時間及強度方面明顯低於有氧，相較於休息狀態，每分鐘換氣量、攝氧量及二氧化碳產生量持續時間在重量訓練約為15分鐘前已回到休息時狀態，而有氧可達60分鐘。結論：重量訓練與達到相似心跳率之有氧腳踏車測試相比較，有氧訓練後，生理狀態較慢恢復到休息時水平。

Background and purpose: While it is known that training modes can influence the excess post-exercise oxygen consumption (EPOC) response to exercise, our study tried to access the EPOC response to different modes of exercise (aerobic exercise vs. weight training) that occurred when performing at the same heart rate intensity. Methods: 14 college girls voluntarily participate in this study. Pulmonary gas exchange system was used to continuously monitor breath by breath gas exchange during aerobic exercise and weight training. Aerobic cycling exercise (70% of maximal hear rate for 25 minutes) and circuit weight training exercise (3 exercises to 70% of maximal hear rate at 10RM) were performed in this study. The weight training program included the use of the leg extension, leg curl, and lat pulldown machines. Results: There was no significant difference in peak EPOC between aerobic training and weight training groups. However, the duration and magnitude of EPOC was significantly higher in aerobic exercise than weight training when peak heart rate of exercise was held constant. When data was compared with the rest condition, pulmonary ventilation, oxygen consumption, and carbon dioxide production fully recover their resting state within 15 minutes from weight training and up to 60 minutes from aerobic exercise. Conclusion: Physiological status needs a longer period to recover in aerobic exercise than weight training.
