Detailed explanation-1: -The lactic acid needs to be oxidised to carbon dioxide and water later. The creation of lactic acid (which needs oxygen to be broken down) generates an oxygen debt that needs to be repaid after the exercise stops.
Detailed explanation-2: -Oxygen debt After exercise, the lactic acid has built up and caused an extra need for oxygen – called the oxygen debt. Lactic acid Chemical produced by the incomplete oxidation of glucose (anaerobic respiration).
Detailed explanation-3: -The amount of oxygen required to remove the lactic acid, and replace the body’s reserves of oxygen, is called the oxygen debt. When someone who has been exercising pays back an oxygen debt, it can take from a few hours for normal exercise, to several days after a marathon.
