Answer 1

If you breathe faster, each breath has less time in the lungs for oxygen to diffuse into the blood and CO2 to diffuse out. You are not going to get much extra effect. Vigorous exercise going into oxygen deficit leads to other chemistry taking over to generate energy and lactic acid building up in the tissues.
