吸热脊椎动物的休息和最大水平的氧气消耗量平均超过外温动物的五到十倍。恒温动物有更广泛的活动范围，可以通过这种增强的有氧代谢来维持。外温动物在活动期间更依赖于无氧代谢，并受其限制。恒温动物进化的一个主要因素是有氧能力的增加，以支持持续的活动。
Resting and maximal levels of oxygen consumption of endothermic vertebrates exceed those of ectotherms by an average of five- to tenfold. Endotherms have a much broader range of activity that can be sustained by this augmented aerobic metabolism. Ectotherms are more reliant upon, and limited by, anaerobic metabolism during activity. A principal factor in the evolution of endothermy was the increase in aerobic capacities to support sustained activity.
