What is oxygen debt ?

Oxygen debt : During active work or exercise, the rate of oxygen supply by the lungs falls short of the requirement of the muscles. Hence, the muscles start respiring anaerobically and lactic acid accumulates in the muscles. The breathing rate gradually becomes high to enhance O2 intake by the lungs. This is called oxygen debt. Hard breathing continues for sometime even after the work or exercise is finished and this is to restore the depleted store of ATP and glucose to normalise the oxidative processes by reutilizing the accumulated lactic acid. red that persons with insufficient supply of glucose are incapable of hard physical labour.
