Often referred to as “after-burn”, EPOC stands for excess post-exercise oxygen consumption. It is the actual amount of energy (calories) that the body continues to burn post-exercise.
I speak often about high intensity interval training (HIIT) on Catapult Fitness Blog. HIIT is done by alternating brief periods or high intensity work (85% or more) with a brief recovery period. HIIT is an example of an anaerobic exercise, which means that an inadequate amount of oxygen is being delivered to working muscles during the course of the exercise.
When inadequate oxygen is available lactic acid is produced.
