Quizplus · Accepted Answer

Long-term exercise (>30 minutes) relies primarily on aerobic metabolism, which uses oxygen to produce ATP. Anaerobic metabolism, which does not use oxygen, is primarily used for short bursts of high-intensity exercise. While anaerobic metabolism may contribute to energy production during long-term exercise, the bulk of the energy is produced through aerobic metabolism.
