What does excess postexercise oxygen consumption represent?

It represent the difference between the amount of energy needed for aerobic muscle activity and the amount actually used

Explanation:

Excess post oxygen consumption refer to the increase in taking oxygen after undergoing exercise or strenuous activities. It is measurable and represent the difference between oxygen needed for aerobic muscle activity and the amount actually used.

During exercises the muscles consume more oxygen to produce energy, until it drop below a threshold level and later on energy is produced from aerobic respiration.

The oxygen increased consumption rate used to restore the body in a resting state and return to pre exercise state.
