I read where they take the VO2 Max novice racers, to see if it would be worth training them for something like the TDF and if they could more or less hold there own. I also know from running, years ago, that you could get more oxygen in your body the longer you keep training. Doesn't the same thing go from riding? I find it hard to believe that they would sideline a potential racer just from a VO2 Max reading. I really dont know what it's all about, but trying to learn.
The reason I ask, is that I have asthma and I would think it would help me build my lungs up. Or get more oxygen in my body. I'm not going racing, but don't you think it would help?
