      When the athlete runs in the race, his body needs more energy. In order to get extra energy, the athlete breathes faster. Because more oxygen is supplied to our cells. It speeds up the breakdown of food and more energy is released.

      After finishing race lactic acid is accumulated in muscles. This causes stiffness/ cramps in muscles. Faster and deeper breathing improves oxygen supply to the muscles converting lactic acid into carbon dioxide and water.
