I agree.Walrus said:Tyler,
some people get different meanings from the term Co2 tolerance. When I talk of CO2 tolerance, I mean your bodies response to high CO2, not how many contractions you can tolerate. I would call that 'contraction tolerance' perhaps, it's really just willpower.
I understand your reasoning but I think it is oversimplified because of the fact that it can easily be very misleading. If that was the only variable then I would agree you spotted his CO2 tolerance. However, I pointed out, in my previous post, a number of known variables which emphasize that given any 10 people who have contractions starting at the same time and you will find their CO2 levels have significant variances, or if their contractions begin at differing times the person who gets them the latest may be experiencing the least CO2 tolerance. This is using your definition of CO2 tolerance. You would have no means of determining if they were currently experiencing high CO2 levels. And that is why I said measuring would be required.Ryuzo does an extremely mild breathe up, in that he hardly purges at all, and gets very late urge to breathe and contractions. So how I understand the term he has very high natural CO2 tolerance.
Scientists here found that freedivers have a higher ventillation ability/efficiency than non-freediving participants. Meaning they could expel more CO2 with the equivalent effort as a non-trained participant. This implies training variances will affect variances in initial CO2 levels. Your blood and tissue acidity is known to be highly adjustable by diet. Buffers are adjustable. Metabolism is highly adjustable.From what I've seen with people it's mostly a genetic thing, some people seem to be able to improve it most I know can't. For most people I know, myself included training CO2 tables only has a temporary effect that lasts a few weeks.
I have not seen any argument that tries to explain how given this information, genetics can still be implied to be the main source of current experienced abilities. If you are saying the plateau, or theoretical barrier is due to genetics, then I might agree, but that is largely useless to refer to in my opinion because you never know what it is. There are many who were plateaued for ages at some level that you could claim was due to their gentics, yet suddenly they leap forward in performance by over 1 minute.
Well, unless you present some numerical evidence, since your definition of CO2 tolerance is "response to high CO2", you have no way of backing up the idea that "CO2 tolerance is really not subtle". By your own definition explain what supports that proposition? The fact that there are such huge differences experienced amongst people after hyperventilating implies what with a high degree of certainty? Being quite alkaline very easily "could" be a big part of it, but considering your alkalinity is "very easily" adjusted, diet is more likely a big part of it, especially since we all have such differences in dietary lifestyle.CO2 tolerance is really not that subtle that you have to measure it. Even if I hyperventilate to the absolute max I can only delay contractions to maybe 4.30 on a max and still get heaps, 50+. For other people they would get no contractions at all until they reach blackout level. Being quite alkaline naturally could be a big part of it.
Cheers,
Tyler
