MCH - the O2 trainer is different than what I was thinking about. I'm going to look into that further since I already have restricted airflow maybe it'll help maximize what I can do.
The O2 trainer is not a altitude mask. You are confusing the two. The purpose of the O2 trainer has nothing to do with altitude training. It trains you Alveoli, and as the article you post said of course there is a limit to what can be achieved. Much like everything else! Lot's of people talk but few with any real world experience with the O2 trainer. Is it magic? Hell NO. Does it work? Yes it has for me.
Yep, the altitude mask is what I was thinking about. Back when I was on triathlon forums there was a lot of discussion about those and the limited usefulness based on what Battue described. Haven't had time to research the O2 trainer yet.
