how does deep breathing help you when running

Taking in oxygen as you run helps keep your body from producing too much citric acid which can make your muscles inflamed which causes you alot of pain.

same as question above but it is LACTIC ACID NOT critic acid lol

l dont think it does..
it takes longer to completly fill up your lungs with air because when you increase the air in your lungs it also increases the preasure that the ribs have on the lungs so its harder to get that last bit of air into your lungs to make it a deep breathe.. to maximise the amount of oxygen that you take in.. it would be best to have moderatly sized breathes. :)

Deep breathing= Greater Oxygen intake= More efficient oxygen delivery to vital muscles.

1. If u do not breath u will faint .
2. If u do not breath enough u will faint.
3.If u breath minimal only through nose & out through nose u will become dizzy.
4.It takes oxygen through ur body to keep u going:)
5.More oxygen u can pump through ur thighs longer u probably will lasy.

p.s In ur nose out ur mouth if thats not enough oxygen for u in ur mouth out ur mouth. The mouth is the biggest hole to take in oxygen:)
