I'm little confuzed...
I tought that the contractions means the urge to breath but it looks like not. What is the diference,is it OK to push with the contractions during the apnea...


Contractions come after the urge to breathe stage, they feel like your body is trying to suck down oxygen when it really isnt.

Yes and No

The contractions of abdominal (and even thoracic) muscles during apnea have been related with the urge to breath, and of course they are. But isn't only urge to breath they are related to "acid", "CO2" and mental status.
The blood acidity depends on many factors:Electrolytes concentration, buffers (albumin, phosphates, bicarbonate) concentration, and CO2 concentration. a profound acidity will stimulate your respiratory drive (urge to breath).
This contractions can be controlled, in fact, my brother(PB 8'12") dont have any contraction 'till 7'. And when is impossible to hold it, he concentrates to make is as smooth as possible that are unnoticeable.
My advice is that try to train holding the contractions,and when it comes make it very smooth (strong contractions consume a lot of oxygen)
Gracias Frank,
I was wondering if it was better to control them or let them loose and ride with them. I noticed that it is possible to control them to some extent but was doubting if doing so was actually using up more O2.

yes, i can hold them for some while, but i didn't know if that was OK so... thanks a lot!
