Because you are making the heart work faster, having to pump more blood round it. Blood needs oxygen and therefore you pant.

∙ 15y agoMuscles, as they expand and contract, use two resources: Nutrients (Carbohydrates and calories) and oxygen. Oxygen is absorbed into your bloodstream through your lungs. As oxygen in muscles is depleted, without being restored, a runner can feel what you know as cramps or tired muscles. Muscle fatigue can be overcome by sufficient breathing before, during, and after a race, warming up, and stretching. Remember to breathe deep and stretch after a run to stop lactic acid, another cramp causer, from building up.
