Define the EPOC (afterburn) effect and give one short worked example.

# EPOC (Afterburn) Effect **EPOC** stands for **Excess Post-exercise Oxygen Consumption**, commonly called the "afterburn" effect. ## Definition EPOC is the elevated rate of oxygen consumption that occurs after exercise as the body works to restore itself to its pre-exercise state. During this recovery period, the body continues burning calories at an elevated rate even though you've stopped exercising. ## Why It Happens After intense exercise, your body needs extra oxygen to: - Replenish ATP and creatine phosphate stores - Remove lactic acid - Repair muscle tissue - Restore oxygen to blood and muscles - Return heart rate, breathing, and body temperature to normal --- ## Worked Example **Scenario:** Sarah does a 30-minute HIIT workout that burns 300 calories during the session. **EPOC Effect:** - Her metabolism remains elevated for 6-8 hours post-exercise - EPOC typically adds **6-15% additional calorie burn** after intense exercise - Additional calories burned from EPOC: 300 × 0.10 = **30 calories** **Total calorie expenditure:** 300 (during) + 30 (EPOC) = **330 calories** *Note: EPOC is more significant after high-intensity exercise (HIIT, heavy strength training) compared to low-intensity steady-state cardio.*
