Running with mouth open

Question

i have heard that all the african guys that win the marathons breath through their noses when running instead of breathing with their mouths open. I am a soccer player so any extra boost can help when im workin out, is there any truth to this?

Answer 1

Running with your mouth open can dry your mouth out and dehydrate you. You should breath through your nose or in through your nose and out through your mouth.

Answer 2

I once heard Frank Shorter asked this question.  He said he would breath through his ears if he could.  If you are working hard you will not be able to just breath thru you nose.  I have seen Kenyans in both practice and in competition.  They breathe thru their mouths.
