Q

First law of thermodynamics

A

Energy is never created nor destroyed, only transferred.

17
Q

Excess Post-exercise Oxygen Consumption (EPOC)

A

The state in which the body’s metabolism is elevated after exercise.

The purpose is to produce additional ATP to reestablish baseline levels & to clear metabolic waste products
