READ ON! EXPERIMENT BELOW.
> Thanks for responding.
It is true, I wouldn't have considered such a thing as held breath
underwater swimming if it hadn't been for you, so thank you for that.
I don't understand the permanent expansion of the cartoids thing. Why
three weeks? I have not access to the american PDR manual. Did you
get your information from this manual alone? Does the manual suggest
that the cartoids are permanently expanded after some weeks? What
about the mammalian diving response? I take it from you response that
you are not interested in digging up information from the internet,
that can be added to your internet article.
I will introduce a simple concept called a breathing cycle, which is
the time from you start an in-breath, till the next time you start an
in-breath.
You can all test your breathing cycle. Try not to 'cheat', as you may
start breathing slower upon focusing on the breathing.
Sitting and relaxed, I have a breathing cycle of 4 seconds. I'm a
slow reader(using this as a measure of attention span) with average
comprehension. After running fast and getting a breathing cycle of
1,5 seconds I had very poor comprehension when trying to read a
biography, forgetting what I had just read.
I got three other persons to test their breathing cycle. Their
breathing cycles were:
3 seconds - slow reader, average comprehension
5,5 seconds - pregnant woman, slow reader
6-7 seconds - poor reader (tested a few times)
(For fun I also tested a cat, which had a 2,4 second breathing cycle,
sitting up-right, looking out the window. When something caught his
attention and he was staring intensly, he had a very slow in-breath or
maybe he was holding his breath.)
This just to collect some data on the breathing span of folks that has
not done the underwater swimming. Well, I did it for three weeks,
with 20 minutes total time under water every day, but I don't think my
breathing span changed because of that.

TO THOSE READING THIS, CAN YOU TEST YOUR OWN BREATHING CYCLE AND PLACE
YOURSELF IN ONE OF THESE CATEGORIES:
- never done the held-breath underwater swimming
- been there, done that (and how long time ago?!)
!Be aware that you may breathe unnaturally slow upon testing your
breathing cycle.
Nice if you can also include your experienced attention span in
attention-demanding situations.
