What is oxygen debt and when does it occur?

Answer 1

The Oxygen Debt is the extra volume of oxygen consumed by muscle tissue after intensive exercise. It is also referred to as recovery oxygen or excess postexercise oxygen consumption (EPOC). EPOC - excess post oxygen consumption
Oxygen debt is the amount of extra oxygen required by muscle tissue to convert accumulated lactic acid to glucose and replenish depleted ATP following vigorous exercise.

Answer 2

In intensive exercise, the human body begins anaerobic respiration to give you more energy. Anaerobic respiration causes oxygen debt as it doesn't use oxygen to produce the energy (it only uses glucose). This causes a build up of lactic acid which needs to be broken down (unless you want permanent cramp) which is done with oxygen which needs to be inhaled after exercise. This is called oxygen debt.

Answer 3

Oxygen debt is where the demand for oxygen is greater than the supply. This means the body is working hard and breathing in a lot of oxygen, but cannot absorb enough to cope with the level of activity.

Answer 4

The body uses a lot of oxygen during and following vigorous exercise. Therefore, more oxygen than normal has to be taken in following exercise to restore the body to its pre-exercise state. This additional oxygen is known as oxygen debt.

Answer 5

When we exercise, we use up a lot of oxygen and our supplies can get exhausted. For example if you find yourself running for a bus, you will see that you will need to catch your breath when you manage to get on. That is because your body is making you take in more oxygen to replace your oxygen levels. That is known as oxygen debt.
