Oxygen Consumption Recovery Graph

What is Oxygen Consumption Recovery Graph?

A recovery graph plots the rate of oxygen consumption against time before, during and after vigorous exercise. It shows a steady resting rate, a rise to a higher rate during exercise, and, after exercise stops, a rate that stays above the resting value and falls only gradually back toward it. The shaded area between the curve and the resting rate after exercise represents excess post-exercise oxygen consumption, the extra oxygen used in recovery, chiefly for the breakdown of lactic acid in the liver.

This definition is part of the Respiration chapter in Cambridge O Level Biology.
