When you pant after a sprint, you are paying the 'oxygen debt. Exercise that helps your body take in more Oxygen causes a build-up of lactic acid, a waste product. Once the exercise is over, the liver processes the lactic acid using oxygen to break it down. The oxygen debt is the amount of oxygen you must take in to process the lactic acid that has built up.
