Question

Activities that can result in oxygen depth

Answer 1

Explanation:

The build up of lactic acid; during strenuous exercise is poisonous and makes the muscles ache; oxygen is needed to break down/get rid of the lactic acid; that is why athletes continue breathing heavily even after the exercise is over; the oxygen needed to get rid of the lactic acid is known as oxygen debt.

Answer 2

Removing the lactic acid after exercise is the cause of the oxygen debt – the oxygen debt is why you breathe deeply after exercise for some time. ... In the liver, the lactic acid is converted back into glucose. This reaction requires energy, hence the extra need for oxygen (for aerobic respiration to provide that energy).
