Excess Post-Exercise Oxygen Consumption (EPOC) refers to the increased rate of oxygen intake following strenuous exercise, as the body works to restore itself to its resting state. Often called the "afterburn effect," EPOC occurs because the body uses extra oxygen to repair muscles, replenish energy stores, and regulate temperature and hormone levels after intense activity.
During high-intensity exercise, the body consumes more oxygen than usual, creating an oxygen deficit. After the workout, EPOC helps repay this deficit by using oxygen to convert lactic acid into usable energy, restore blood oxygen levels, and rebuild depleted glycogen stores.
EPOC also elevates the metabolism for several hours after exercise, meaning the body continues to burn calories even at rest. The effect is most pronounced after high-intensity or interval training, making EPOC a key factor in improving fat loss and cardiovascular health, while enhancing overall recovery and performance.
