Hiya,
Your body respires anaerobically when it can't take in enough oxygen during hard exercise to respire aerobically

The muscles need more oxygen to convert to energy during harder exercise...
But the blood can only supply so much.
This means the muscles create an oxygen debt by converting glucose into energy and lactic acid.
However this can only work short term, and the build up of lactic acid will cause the muscles to fatigue (ache)
In lower levels of exercise, the body is able to provide the working muscles with enough oxygen in the blood, and so aerobic respiration is done instead

Why is it that you always answer my science questions?

Thanks Pizzaa<3 you've actually helped me a lot today!:cool:

Anaerobic respiration happens for around 2 minutes, during this process your body doesn't use any oxygen and Lactic acid builds up. Aerobic respiration is when your body uses oxygen. During hard exercise anaerobic respiration will happen if your body isn't taking enough oxygen in. After anaerobic respiration your body will have a 'oxygen debt' where you have to breathe rapidly in order to pay back the oxygen lost
