Why does an athlete breathe faster and deeper than usual after finishing the race?

Our body needs energy for all activities, which is provided by the oxidation of food during respiration. During intense physical activities like running, jumping, playing games like basketball, hockey, football etc.  There is a greater demand for energy to perform these activities. Hence, more oxygen is required to meet this extra demand for energy.

An athlete breathes faster and deeper than usual after finishing the race.

During the run, the energy demand is high, but the oxygen supply to produce energy is limited. Therefore, anaerobic respiration takes places in the muscle cells to fulfil the energy demand. After finishing the race, an athlete breathes faster and deeper than usual to supply more oxygen to the cells. Therefore, an athlete breathes faster and deeper than usual after finishing the race to provide extra oxygen and hence extra energy to the body.

Glucose during running

An athlete consumes a lot of energy during running, which is produced by the oxidation of glucose. By breathing deeper and faster, the athlete is basically consuming more and more oxygen to meet his or her energy requirements.
