Part of the excess postexercise oxygen consumption is due to increased speed of chemical reactions resulting from an increase in body temperature.

Question

Quizplus · Accepted Answer

Excess postexercise oxygen consumption or EPOC, also known as oxygen debt, is the oxygen uptake that occurs after exercise to support the body's return to its pre-exercise state. One of the factors contributing to EPOC is an increase in body temperature, which results in an increase in the speed of chemical reactions and, as a result, an increase in metabolic rate. This phenomenon is known as excess postexercise oxygen consumption via thermogenesis.
