Thank you Baiyoke for the link. I had not read that thread before and it was very informative.
I did glean that maximal spleenic contraction takes 7-8 minutes in humans, and efattah's observation that spleenic contraction during max attempt apnea would be most beneficial makes a lot of sense. I also noticed that 10 minutes is the time for spleenic contraction to wear off.
In my experience doing static tables, they get progressively easier and my ventilation between holds tends to stablize at a pretty relaxed level--need to breathe just decreases.
CO2 work tends to sit with me for a while. For a max attempt it might make some sense to do a long CO2 warm-up, take 15 mins off for spleen to return to baseline, then perform a max attempt. I don't know if I could make it to 7-8 minutes that way but it could be worth a try... I typically end a dry static O2 table at 5 min, doing70 sec rest between each.
Does anyone have data on what spleenic contraction is for trained divers? Johan's study was on untrained subjects and they were coming in at 3%-6%.
