But understand 100 percent vo2 max is the point where you can no longer exercise and vomiting often starts. From the Sports medicine site I checked "
Measuring VO2 max accurately requires an all-out effort (usually on a treadmill or bicycle) performed under a strict protocol in a sports performance lab."
As you may know the USADA and the UCI have been working on tests to measure the vo2 max of riders and anyone that ever tested at 170 percent would be bounced for EPO. But I agree if someone could suck in 170 percent of the oxygen necessary to continue racing, running or exercising that would be difficult. Sounds like some people estimate vo2 max like others do calorie counts.
I'm not a fitness guru, so I could be wrong, but the way I understand it, in layman's terms: You achieve 100% VO2 when you become breathless. Increase your output from there, and you get it up over 100%. At least that's the way I think of it.
I know I am not achieving 170%. I'm probably getting a little up over 100%. Funny thing is, since i started doing the Tabata, my VO2 capacity has increased so dramatically, that it out-paces my muscles- in other words, I now max-out my muscular strength long before I max-out my VO2....so I can not go hard enough now, to elevate my VO2 any more. (In the original Tabata study from 1996, they did not have this issue, as they used trained athletes....).
