Oxygen debt

In this article, we will discuss about Oxygen Debt. So, let’s get started.

Oxygen Debt

When the rate of muscle work/activity is greater than the amount of oxygen supplied by the body eventually leading to shortage of oxygen and results in fatigue. This shortage of oxygen is called Oxygen Debt. In other words, if an anaerobic activity takes place over a long period of time then muscles soon becomes exhausted because of a condition known as Oxygen Debt.

Strenuous activities use up all ATP and produces lactic acid. This lactic acid can only be removed in the presence of oxygen and hence the oxygen debt should be repaid post completion of strenuous exercise. Panting is a way in which we replenish oxygen (promote oxygen recovery) and remove lactic acid.
