trux, thank you for your advice, I surely need alot of info regrading freediving physics and chemistry .. I hope we'll have loads of these information through the freediving courses we shall have next month, and reading speciality books is very important too ..

Samba or correctly LMC (Loss of Motor Control) is a neurological failure due to hypoxemia. The shaking is not necessarily the same as convulsions, contractions, or spasms trying to deliver oxygen to the brain.
|
So if I got it right, there's no relationship between those movements in a LMC case and the body trials to deliver O2 to the brain. or could it be associated with such trials, what do you mean by "not necessarily" ?

And what you experienced after you breath-up was a blackout (or a state close to it) due to brain hypoxia induced through hyperventilation (and accelerated by the pressure change) and not because of relaxation and low heart rate.

I'm not quoting the whole paragraph, it can be read in your post ..
Now excuse my poor english trux, but didn't you say that the hyperventilation is reducing the CO2 in blood ?! .. which is correct.. how come there will be CO2 "EXCESS" which would increase the blood acidity and causes a stronger O2 hemoglobin bindings?!
Plus, if I am not mistaken, isn't the hyperventilation as a term descripes FAST SHALLOW breaths, which will decrease CO2 level in blood SHARPLY without increasing O2 levels? while DEEP SLOW breaths will both increase O2 level and decrease CO2 level but NEVER to the extend of delaying the body reflex toward higher CO2 levels?
I was doing very very slow and very deep breaths for about 20 minutes before standing up all of the sudden. It is very clear in my post that the major reason for the dizziness in my understanding is the sharp drop in blood pressure, which you agreed that is an accelerating factor.
Anyway, what you said could make alot of sense .. I just think I'm missing something in between ..
It's a good luck for me that a cardiologist is visiting our home for couple of days, I think I'll have a conversation with him about the subject, he might be able to explain to me .. Thanks alot bud ..
