Question

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

Answer 1

Answer:

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

Answer 2

When the athlete runs in the race, his body needs more oxygen. His rate of breathing increases so that more oxygen can be supplied to the body muscles as the demand of energy is high at that time. But, the supply of oxygen to produce energy is limited. After finishing the race, an athlete breathe faster and deeper than usual so that more oxygen is supplied to the cells. Thats why an athlete breathe faster and deeper than usual after finishing the race.
