"Lance has never doped." "Lance is clean." "Lance has taken dope once." What of the above is the mythical non-provable negative? I would argue that you could prove that "Lance is a doper" or that "Lance has taken dope once" by simply coming up with the guy that sold him the dope or that witnessed him taking it or who taught him how to use it. You just don't "take" dope without knowing the right people and what to do. Even if it doesn't prove he doped, you at least have witnesses. How does Armstrong prove he's NEVER taken dope? How can you prove that? If he says "I've never tested positive" you say "that doesn't prove anything". If he says "There are no witnesses" you say "how convenient" or "just none have been found". There's always an excuse for NOT coming up with proof. The sad thing about people like Lafferty and Walsh (and, btw, the people who claim that the U.S. never went to the moon) is that they will go to their grave believing what they believe even if no evidence comes forth. They will just continute to say "what he did was not possible, therefore he must have used dope" regardless of any evidence. It's almost a religious fanatacism with them. Once agin, if proof comes out then Armstrong deserves the consequences. But until then give it a rest. |

"B. Lafferty" wrote in message link.net... "Philip Holman" wrote in message ... "B. Lafferty" wrote in message news "Philip Holman" wrote in message ... "B. Lafferty" wrote in message news wrote in message ups.com... vayer's argument ... it doesn't hold a lot of water, in the same way as *all* the lance arguments (pro and anti) don't hold a lot of water. they're not supported by strong evidence. too many of them come down to what an individual wants to believe, and are just used as supporting buttresses for that belief system. vayer's argument seem to boil down to the fact that "man goes up hill fast? drugs are the only answer." i'm sure you can give an alalytical response to an argument that itself is not nearly as analytical as it pretends to be. vayer's statistics don't wash, no with me anyway. can you compare the times to go up the same mountain in different races? what about all the contributory factors, from weather through tactics through where the mountain falls in a particular race. you also have to account for the overall changes in the race itself - shorter, flatter, less tiring (though still not easy). there would also seem to be an assumption on vayer's part that, on a climb, riders go balls out base to summit. that simply doesn't hold water. there are, at the end of the day, too many assumptions in vayer's analysis. on the other hand, there is a relevence to vayer's argument. michele ferrari had certain areas of specialisation. vo2 max and hill climbing being the important ones, where vayer's argument is concerned. maybe vayer does have a point. but i don't think it's a well made point. but then, maybe he was afraid of ferrari suing him, and so couched it too carefully. The hill climbing part of the analysis seems to be the most certain of what he did. You know the rider's weight, the weight of his machine, the distance and gradient climbed and the time for same. I'd like to see someone with the expertise of a Keen (or Ferrari?) respond to that portion of Vayer's analysis. The "experts*" of rbr have given Vayer short shrift, deriding him as a mere "gym teacher." And yet, much the same formula appears to have been used by Floyd Landis' coach in projecting what was probably Floyd's maximum sustained climbing output on at least one major climb this year. IIRC, that number was around 370 watts. *Andrew Coggan, perhaps the most expert in exercise physiology posting here, has not, to my knowledge, done a point by point analysis of what Vayer has written in the Walsh book. I'd like to see a magazine like ProCycling pull together several experts for a discussion of what Vayer has done. Using Andrew Coggan's power tables, a world class cyclist can develop 6.14 watts per kg of body weight whereas a world champion can develop 6.62 over a 20 minute time period (assuming Lance weighs about 70kg this equates to 463 watts). In climbing and given the same body weight this will result in almost the same proportions in climbing speed. Say 15 mph versus 16 mph. As for FL's unremarkable 370 watts, that's about equivalent to what a UCI division III pro can sustain for 20 minutes. Vayer's analysis boils down to Armstrong being the best so he must use drugs with a bunch of very unscientific comparisons and estimates thrown in to sway the uninformed. Phil H Looking at http://www.cyclingpeakssoftware.com/...profile_v3.gif it appears that the top level Coggan presents at functional threshold is 6.4 Consider that Armstrong is, according to Vayer and Ferrari as quoted in Coyle's book, putting out a ft level of 480-500 watts with a magic number of 6.7 (according to Ferrari) This is all done with a measured VO2Max of 82 or 83. Eddie Coyle speculates that Armstrong *may* have a VO2Max at present of 85 (Coyle has apparently not been able to confirm that speculation with lab tests). Coyle goes through a rather labored attempt to explain this FT power output by speculative muscle fiber conversion theories not supported by muscle biopsy and hyperbaric living. But there are other possible explanations. What Vayer asserts is that Armstrong's FT output is virtually impossible with the VO2Max that he has. BTW, Floyd Landis has a VO2Max of 90 and Ullrich's is 88. I'd like to read a discussion of this by Coggan and others in the field such as Keen. It's fairly well known that VO2 Max is NOT a good predictor of athletic performance and that power output at anaerobic threshold is. Some athletes can obtain a higher percentage of VO2max at AT. There is plenty of scientific research to support this. VO2 max also does not take into account gross efficiency. Thus the journal article by Eddie Coyle that really doesn't explain (or prove) a natural basis for Armstrong's increased efficiency. He does in this one. http://www.ncbi.nlm.nih.gov/entrez/q...97&query_hl=13 Phil H |

No, then you're not cheating, because you know it isn't affecting your performance. You're getting busted for not-cheating. So by saying that you are saying it is up to every individual to make up his(or her) own mind as to wether he is doping or not... it's the individual's morals... dangerouse mate... the door's WFO if you go down that road.. No, I'm not saying that. I'm saying there is a distinction between cheating and rule-breaking. Cheating generally requires intent to subvert the competition (or willful ignorance, like taking what Willy Voet gives you and pretending not to know what's going on). Somebody who takes cold medicine that is not performance-enhancing and gets busted for it is not cheating, but they are breaking the rules. But like I said, it's an imperfect world. So even if the governing bodies are completely honest, the best they can do is make a set of rules that catches cheaters and doesn't catch too many non-cheaters. You can't make rules that punish people who don't get caught, so in the end you still have to rely on people's own morals to not cheat. The problem is when the culture or competitive pressures of the sport demand that they set their morals aside. No, I think you have to go by the rules, those are the only true guidelines that don't involve individuals resting on their moral upbringing to make a dicision... and sadly, if you go by the rules... "you don't get cought, you're clean." (In fact half the time wit lots of federations you can get cought and still be clean.. but that's a separate issue alltogether. Let not go into that.) |

IIRC, that number was around 370 watts. Oh for crap's sake. Nobody is arguing with the idea that you can plug weight, gradient and speed into a formula and get power output. It's not rocket science. Chung, Holman, Schwartz, amit, I, or anyone with access to http://www.analyticcycling.com, including you, can plug in the numbers and get an estimate of Armstrong's power. The part of Vayer's "analysis" that people were poking fun at last time is the one where he tries to compare riding Alpe d'Huez to doing leg-lifts with weighted bags on his legs, which is a pretty meaningless comparison anyway. A huge problem with Vayer's argument - pointed out by amit at http://groups-beta.google.com/group/...f30b3f00f0cc03 is that you can't go from a wattage figure and a V02max (or VO2 at threshold etc) to a deduction that the wattage is reasonable or physiologically impossible or evidence of doping or whatever. Because there just is not a very good correlation between V02max and wattage at threshold from person to person. *Andrew Coggan, perhaps the most expert in exercise physiology posting here, has not, to my knowledge, done a point by point analysis of what Vayer has written in the Walsh book. I'd like to see a magazine like ProCycling pull together several experts for a discussion of what Vayer has done. Cooglie only lurks here intermittently, why don't you email him the English translation and ask him? Speaking of Floyd's coach Allen Lim, here is an article: http://www.bicycling.com/tourdefranc...expert,00.html In the stage 20 TT, his model predicts that Floyd averaged 379 watts. To ride as fast as Lance, Floyd would have had to put out 410 watts. (That doesn't mean Lance put out 410 watts, because he has different weight and aero drag, but somewhere in that neighborhood.) This is a TT and 1 hour plus, so climbing wattage might be somewhat different. I don't find either of these numbers incroyable. |

That very true... but in the eyes of the law/govering bodies etc...
there is no destinction between cheating and rule breaking. In fact the whole idea of "cheating" is subjective, so you could say there is only rule breaking. If I take Amphetamines for some race, you would say it is cheating (and I would agree with you), but if everyone else is taking them too, is it still cheating? Well, not really because you aren't getting an unfair advantage, but it is still rule breaking. You are dead right, it is an unfair world, and I think you have pretty much said that there is no actual solution to the probleme, and I would have to agree with you. |

My only point was one can't take the matter into philosophy or whatever by applying a general (and wrong) principle like "you can't prove a negative". Otherwise I agree with everything you say, and also about the practical (not principal) issues when trying to prove "Lance has never doped". |

until then give it a rest. You like this one don't you?! Again, I think it is too simplistic a view. Consider: he's found to have been +ve, they take a title away from him, and give it to 2nd place; ie: someone who (may have) used the same stuff... would that be OK? Would he have got what he decerved? |

Sandy wrote: Another thing I didn't like is the riders=Robocop cliche. I gather this is popular among Armstrong-haters in France No defense of France here, but I think you (and lots of others) may be concocting your own vision of what the French think. On TV, FR2, for example, he is the focus of enormous enthusiasm, idolatry, admiration and respect, as a cyclist. Recently, the slightly "hot" version of Armstrong - the Sheryl Crow stuff - makes him even more enviable and popular. I didn't intend to imply that it was common in all of France, (last week I was defending Leblanc from the charge of anti-Lanceism), just a cliche among a minority with anti-Armstrong sentiment. Google "robocop" in this newsgroup to find some of Ilan's posts on the subject. What I have written, what some (not all) French feel, is that broad scale racing has suffered from the overwhelming focus on a single event. It's not just Armstrong's monomania that nettles. It's the market domination and dilution that accompanies it. I mentioned that if the World Series (baseball) were like the Pro Tour and the TdF, no one would have to win regularly, just show up for the round-robin final by invitation. And a little like golf, where course management is all that counts towards the final score. The only race Armstrong won, of 20 in this year's tour, was one time trial, and nothing in line. He is a masterful rider, and those who want to chant "Drugs, drugs, drugs" seem more envious than critical. He wanted only one prize, he did all possible to achieve it, and did it 7 times. Criticism is not exclusively French in character, although I think Europeans are more sanguine about doping. Well, he certainly raced this one conservatively. I think he got more conservative as he aged, which is prudent, but less exciting. I would like to see more of a free for all now that he is gone, and surely the next Tour will be more wide open, but I wouldn't be surprised to see elements of conservative racing again. The stakes are too high for anyone but a complete dark horse to take a big gamble. Armstrong says he has finished. The next tour is eleven months away. I sure hope other subjects manage to attract attention. This forum could cavitate from the absence of both in the interim, and it would not be all that bad. Well, the volume of posting always drops off after July. For the OP of this thread, Armstrong appears gone but not forgotten. A year from now, we may have found something else to talk about. I wonder how the rbr volume and the US interest in bike racing will taper off next year. |

Thanks for your post. You said that people who say Armstrong is clean (for example, Lance Armstrong himself) can't prove it. How is one supposed to prove a negative? What could Lance do to "prove" he's clean? Now that he's retired and no longer relies on trade secrets, making public his training journals and US Postal/Discovery team doctor notes (they can't be confdential if the patient wishes them disclosed, can they?) will go a long way to determine if there were any wasps involved. Transparency is the way to go, but LANCE is anything but transparent. |
