When you do vigorous exercise and your body can't cupply enough oxygen to your muscles, they start doing anaerobic respiration instead of aerobic respiration. This means that it is an incomplete breakdown of glucose which produces lactic acid.
Glucose----->Energy+Lactic Acid
This is not the best way to convert glucose to energy because lactic acid builds up in the muscles, which gets painful. It also causes muscle fatigue which means that the muscles stop contracting efficiently as they get tired.
It also doesn't release as much energy as aerobic respiration.
The advantage is that at least you can keep using your muscles for a while longer.
