I'm new to the forums, and new to freediving - only heard about it a few days ago when i came across this incredible article
(http://www.theatlantic.com/issues/97may/dive.htm)
I do a lot of cliff diving and snorkeling and rock climbing here in oman (middle east) when i'm on vacation, tho i live in toronto. I'm interested in learning more about this fantastic sport.
I do have an important question about apnea, contractions, and co2 tolerance:
From my understanding, the burning desire to breathe arises from a certain level of carbon dioxide that builds up as oxygen is used in the tissues. Contractions occur shortly after the onset of this intense desire. In my experience with breath holding, i come up for air (give in to apnea) when this burning desire reaches an intolerable intensity. I don't think i've experienced contractions yet, tho i may have and mistaken them for the burning desire itself. My question is this: If you ride out this burning desire with sheer will power, will it disappear after a while, allowing you to keep holding your breath for a while after? Or does it keep building up and up and you just learn to ignore it? Does this burning desire subside as if it were a temporary barrier?
peace
