Stands for Excess Post-exercise Oxygen Consumption and indicates the amount of extra oxygen that your body needs to recover after exercise. Due to the physiological training load caused by exercise, your body consumes more oxygen after exercise than during rest.
EPOC describes the general level of the body's homeostasis disturbed by the exercise and is higher the more demanding the exercise has been: the longer a high level of intensity (close to VO2max) can be kept up, the higher EPOC is. EPOC is a measure of exercise load: it integrates the effect of the whole training session and is suitable for measuring accumulated exercises of different intensities and durations. At extremes, EPOC is a measure of fatigue resistance capacity: the higher the EPOC, the more demanding the exercise the individual has been able to perform.
