Question

Quizplus · Accepted Answer

Excess postexercise oxygen consumption (EPOC) represents the amount of oxygen consumed by the body in the period after exercise to restore oxygen levels and metabolic rate to normal. It is the difference between the amount of oxygen needed for totally aerobic muscle activity and the amount actually used during exercise. Therefore, option A is the correct answer. Option B is incorrect because it suggests that EPOC only mirrors the oxygen already used, which is not true. Option C is incorrect because this statement implies that the body takes in more oxygen after exercise, which is not necessarily true. Option D is incorrect because it mentions the oxygen needed to accomplish a specific amount of work, which is not related to EPOC.
