What causes oxygen debt in muscles?

Answer 1

The concept of oxygen debt comes from the use of muscles during periods of extreme exercise. At this period, the muscles begin to burn more oxygen than the lungs and circulatory system are able to provide, so the runner or person exercising feels a burning sensation in the legs or arms and becomes short of breath (breathing more quickly to make up for the debt).

Answer 2

Respiration needs glucose and oxygen to work. However, if you are doing exercise,

e.g. running, your lungs and heart cannot get oxygen to the cells in your legs fast enough. So the cells use carbon dioxide instead of oxygen to respire. The side effect of this is a build up of lactic acid, which is the burning sensation you feel in your muscles when you do exercise.

To get rid of this lactic acid, you need to get oxygen back into your cells. This is called an oxygen debt. This is why you pant/breathe heavily after doing exercise to get the oxygen back to repay the debt.

Answer 3

when the demand for oxygen exceeds supply so you have to replenish it.

Answer 4

the amount of oxygen needed to rid the body of lactate

Answer 5

Oxygen debt - The demand for oxygen is great than the supply.

Answer 6

it mean when you are, in lack of oxygen due to the intense exercise your body's been through.

Answer 7

when you do not get enough energy within the muscles so you get more oxygen by breathing faster and making the energy.
