Question

WHAT IS THE PURPOSE OF EXCESS POST-EXERCISE OXYGEN CONSUMPTION?

A) To cool down the body
B) To replenish energy stores
C) To eliminate metabolic waste
D) To increase heart rate

Answer 1

The purpose of excess post-exercise oxygen consumption (EPOC) is to replenish energy stores and eliminate metabolic waste. It helps restore the body to its pre-exercise state.

Step-by-step explanation:

The purpose of excess post-exercise oxygen consumption (EPOC) is to replenish energy stores and eliminate metabolic waste. During intense exercise, the body generates energy without sufficient oxygen, leading to an oxygen debt. After exercise, the body continues to consume more oxygen to restore ATP and creatine phosphate levels, convert lactic acid into pyruvic acid, and convert lactic acid into glucose or glycogen. This elevated oxygen intake after exercise helps restore the body to its pre-exercise state.
