EPOC is the difference between the elevated rate of oxygen consumption at the end of an exercise and the rate at rest. It occurs in part because exercise depletes your stores of ATP and creatine phosphate (CP). Oxygen is required to synthesize ATP aerobically, and some of that ATP is used to regenerate CP. A small amount of oxygen serves to reoxygenate the muscle myglobin, and the liver consumes oxygen in disposing of the lactic acid generated by exercise. In addition, exercise raises the body temperature and overall metabolic rate, which in itself consumes more oxygen. ATP and CP are replenished in the early minutes of heaviest postexercise breathing, and oxygen consumption remains elevated for as much as an hour more as lactic acid is oxidized. EPOC can be as much as six times one’s basal oxygen consumption, indicating that anaerobic mechanisms of ATP production during exercise allow six times as much physical exertion as would have been possible without those mechanisms.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
