Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
To rid the body of lactic acid, oxygen is needed; the amount of oxygen required to break down lactic acid is referred to as
A
Oxygen debt
B
Oxygen levels
C
Kinetic energy
Explanation: 

Detailed explanation-1: -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: -Alternatively, the liver can break down lactic acid by reacting it with oxygen to produce carbon dioxide and water, which you might have noticed are the same products as aerobic respiration. The amount of additional oxygen that is necessary to remove lactic acid from the body is called oxygen debt.

Detailed explanation-3: -Lactic acid is produced and starts to build up in muscle cells as a direct by-product of glucose being converted to energy. More oxygen is needed to help break down this lactic acid. Oxygen debt-when oxygen can no longer reach cells to break down lactic acid at the same rate it is being produced, oxygen debt occurs.

Detailed explanation-4: -This additional oxygen that is required to be inhaled into the body after a vigorous exercise to restore all systems to their normal states is called oxygen debt. This is also put to use in order to repair muscles. So, the answer is, ‘ Muscle recovery.

Detailed explanation-5: -This is called an oxygen debt. It is repaid after exercise. The oxygen reacts with the lactic acid to form CO2 and water. Rapid and deep breathing is needed for a short period after high intensity exercise in order to repay the debt.
