The term "afterburner effect" in sports and weight loss is also known as Excess Post-Exercise Oxygen Consumption (EPOC). This process refers to the body's increased rate of oxygen intake following strenuous activity. Essentially, your body uses more energy to return to its resting state and that burns more calories after exercise, even while you're not actively exercising. The afterburner effect happens due to the body's physiological responses like replenishing oxygen storage, repairing muscle proteins, and removing lactic acid, among other things. The intensity and duration of the exercise can determine the extent of this effect. High-intensity interval training (HIIT) is believed to generate a significant afterburner effect. While beneficial for weight-loss and fitness goals, it's crucial to engage in these activities responsibly and under expert supervision to prevent injuries or overexertion.
