Cobblestones said:Let's get over what Grappe said:
1) His weight is stable within 900g.
Ok, fine. Neutral statement wrt. doping I guess. Main point seems to be to use W and W/kg interchangeably.
2) Must possess extraordinary aerobic potential.
Qualified by the statement that he does not have the corresponding VO2max numbers. In fact, we can treat this as a scientific prediction. Power numbers can only be explained by high VO2max numbers (which are hard to improve throughout a career). So let's test this prediction... below
3) Must possess excellent recovery.
Hard to use the statement in either way. For doing well in 3 week GTs this is a given. However, I have no idea whether recovery can be trained or not. Certainly it can be helped along by 'products'. I interpret it neutral/slightly leaning toward doping.
4) Power drops off normally
Again, it is hard to use the statement either way, as everybody (athlete or not, doped or not) would presumably show this behavior. If you dope, presumably you'd increase your 60 min. performance as well as your 20 min. performance, but still you would do worse for 60 min. than for 20 min. I just don't see what the drop-off proves in terms of doping.
ok, so far so good
Now, let's go back to point 2, which is the big point IMHO. Does Froome have a VO2max value at the physiological limit? Well, clearly, he has now, otherwise he wouldn't produce the power data, so the real question is: is it a natural or 'enhanced' number? For that to establish, we assume that the 'natural' VO2max doesn't change much throughout a career, because it cannot be improved much through training. So it should be evident throughout Froome's career (in a similar way as it was throughout, say, Greg Lemond's career). Now, you don't need a PhD in statistics or exercise physiology or any particularly sophisticated models to convert ITT times or VAM times into power data and VO2max data to see that there's absolutely no manifestation whatsoever of any extraordinary 'at the physiologocal limit' VO2max value for Froome from anything before the 2011 Vuelta. Now, why would that be the case, I wonder? The official explanation for that given so far is bilharzia. Or did I miss something?
Amazing that the most scientific and revolutionary team in the history of cycling:
Team Sky have never measured Froome's VO2Max – his maximal level of oxygen intake during exercise – but Grappe concludes that this must be "close to currently known physiological limits …
[...]
As any close follower of cycling knows, drug test figures are meaningless in proving a rider's probity, but what they do show is that Froome and his team are being closely monitored, even if they are keeping essential figures to themselves.
