Martial arts is the best example I can think of to explain it...
Making those KEE-YAPS teaches breathing regularity
a repetitive exercise used to discipline the mind and body...
and in ancient days was supposed to create the image of fierce warrior
A psychological advantage used to frighten an opponent
In boxing I would teach my kids to exhale loudly through their nose,
loud enough that I could hear them, if I couldn't hear it, I assumed they weren't
breathing and I would sock them
But I don't scream in the gym -
