Question

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

Answer 1

Answer:

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

Answer 2

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.
