Detailed explanation-1: -These processes require oxygen. This is why, when the period of activity is over, a person’s breathing rate and heart rate do not return to normal straightaway. The amount of oxygen required to remove the lactic acid, and replace the body’s reserves of oxygen, is called the oxygen debt.
Detailed explanation-2: -As explained above, oxygen debt occurs when there is not enough oxygen to keep up with the demand for energy, which is converted from glucose stores. The conversion of glucose produces unwanted lactic acid that oxygen helps to eliminate.
Detailed explanation-3: -Oxygen debt is a term used to describe exertion which causes an increase in lactic acid production. A trained athlete is able to increase the oxygen consumption in their muscles to a greater degree than non-athletes.
