The elevated oxygen consumption during recovery from an exercise bout is called EPOC or ____.
A) oxygen debt
B) oxygen deficit
C) anaerobic threshold
D) fat burning zone

Question

Quizplus · Accepted Answer

EPOC stands for Excess Post-exercise Oxygen Consumption, which is also known as oxygen debt. After exercising, the body continues to consume oxygen at a higher rate than before the exercise, in order to restore the body to its pre-exercise state. This increased oxygen consumption is referred to as the "oxygen debt" or "oxygen deficit" and is necessary to resynthesize ATP, replenish glycogen stores, and remove lactic acid, among other things. Therefore, the correct answer is A, oxygen debt. Choice C, anaerobic threshold, refers to the level of exercise intensity at which the body switches from the aerobic to anaerobic energy systems. Choice D, fat burning zone, refers to an exercise intensity that supposedly maximizes fat burning, but this concept is controversial and not widely accepted.
