EPOC stands for Excess Post Exercise Oxygen Consumption.

EPOC stands for Excess Post Exercise Oxygen Consumption.

• A. Excess Post Exercise Oxygen Clearance
• B. Excess Post Exercise Oxygen Consumption
• C. Exponential Post Exercise Oxygen Cycle
• D. Excess Post Exercise Oxygen Control

Answer: (B)

Excess Post Exercise Oxygen Consumption describes the extra oxygen the body uses after exercise to bring itself back to resting conditions. After activity, you continue to breathe hard and consume more oxygen than you would at rest because the body needs to repay oxygen debt and restore several systems. This includes replenishing ATP and phosphocreatine stores, oxidizing lactic acid produced during exercise, re-saturating oxygen in blood and muscle pigments, and returning body temperature, heart rate, and breathing to resting levels. The phrase that exactly captures this idea is the one that expands to “Excess Post Exercise Oxygen Consumption.” The other options refer to oxygen clearance, a cycle, or control, which do not describe the increased oxygen use after exercise to restore the body.
