Why do athletes breathe differently?

Answer 1

Through training and exercise you can increase your lung capacity and efficiency, therefore all the training done by swimmers will increase their lung capacity so to average swimmre should have larger lung capacity than the average non-swimmer

Yes because of self-esteem. Kids dont feel so welcome for sports if people are always running past them. I should know.

Answer 3

No they just learn to control their breathing better
