Final answer:
The term for calories continuing to be burned after a training bout is called excess post-exercise oxygen consumption (EPOC). During HIIT, the body uses more oxygen and burns more calories to recover and restore itself to its pre-exercise state, increasing overall calorie burn even after the workout is over.
Step-by-step explanation:
The term for calories continuing to be burned after a training bout is called excess post-exercise oxygen consumption (EPOC). This refers to the increased oxygen consumption and caloric expenditure that occurs in the body after intense exercise. During HIIT (High-Intensity Interval Training), the body uses more oxygen and burns more calories to recover and restore itself to its pre-exercise state. This metabolic effect helps to increase overall calorie burn even after the workout is over.
