Question

the breathing rate ofa athletes in much less than that of a person who does exercise.do you think is because athletes needs les oxygen or because ther lung volum is greater so with each breath they absorb more oxygen​

Answer 1

Answer:

Athletes usually train at high altitudes. Oxygen in high altitudes is low. This increases their lung capacity, RBC levels so they get higher levels of oxygen in the same time. Training like this boosts endurance and enables them to meet their high oxygen demand at sea level. This type of training allows athletes to breath less than a normal person.

I wrote this entirely on my own.

Hope you got your doubt cleared :)
