Exhaling during dynamics

[wes]

JimBo,

When I get to the end of my air and feel a bit tweaky, I always blow the air out into my cheeks and puff them out then in and back 4 to 6 times. The recirculates the fresh air in my mouth and throat down into my lungs and I can taste the stale air as it comes up into my mouth. I am sure the extra O2 one gets is pretty minimal, though it should help and gives me something to do so quiets the mind a bit and calms the ego. You might try this to help you relax. I would do this 2/3 of the way thru a static or dynamic a bit before I would get contractions. Good Luck

Exhaling in the end of static may not give you any extra seconds, though if it somehow increases your PO2, it can help you to stay conscious as DeepThought has written.
This needs some experimenting.

Really old conversation. If someone will read, I can add my experience from my first competition. I swam DNF and hit the wall after 25 m :headand unwillingly exhaled pretty much air and lost my nose clip as well. I was thinking of stopping my DNF but decided to continue. Finaly I made 140 and finnished just to be sure that I will not pass to LMC. Week after that I made 150 m so I think that exhaling small amount of air is not so dangerous and doesn't necesserily mean that it reduces your performance .
