Why does an athlete need air and food?

Answer 1

Athletes need a good supply of oxygen in their blood systems to perform at their highest potential. The more oxygen in the blood stream, the more oxygen is available to be transferred to each cells' mitochondria. The mitochondria produces the energy that a cell needs to perform at its best. So, the more oxygen there is in the blood, the better an athlete will perform. This is why athletes train at high altitudes without much oxygen - so their bodies produce more naturally. Then, when they compete at lower altitudes, their bodies have extra oxygen and thus, they are able to perform better.
