Question: 1 / 445

What is the purpose of Excess Post-Exercise Oxygen Consumption (EPOC)?

To decrease oxygen levels in the body

To increase the body's resting metabolic rate

To repay the oxygen debt created during exercise

EPOC is the body's way of repaying the oxygen debt created during exercise. During intense physical activity, our muscles require more oxygen than our body can supply, resulting in an oxygen deficit. EPOC helps to restore the oxygen levels in the body to pre-exercise levels, enabling the body to recover and return to its resting state. Options A, B, and D are incorrect as they do not align with the purpose of EPOC. Decreasing oxygen levels in the body would be counterproductive for exercise and overall health, while increasing the body's resting metabolic rate and stopping ATP production are not directly related to the purpose of EPOC.
