[/quote'] Don't forget that power is relative to weight and so it is more accurate to talk in terms of power/weight. Certainly 6.5 w/kg for an hour has been achieved by Armstrong and Indurain - equating to ~460w for LA and ~500w for Big Mig. That was a max performance estimate but certainly was repeatable up climbs like Alpe D'Huez etc. 7 w/kg has been touted regularly by the physiologists as the the "magic" number that a tour winnner needs to be at or about. So, 400w for Basso at around 70k is, I reckon, possible on those ascents at only .. 5.7w/kg. Are any of these figures clean...I do not know.BikeMax2006-09-18 08:17:27 Link to comment Share on other sites More sharing options...
Cruxpearl Posted September 18, 2006 Share Well Widget,Hasn't it been proven time after time in the last two or three years where you have somebody that, out of the blue or unexpectedly, produces an "extraterrestrial" or unbelievable performance, that they are soon thereafter caught or implicated in some doping scandal or dabbling with EPO.Raimondas RumsasDavid MillarTyler HamiltonSantiago PerezRoberto HerrasIvan BassoJose Enrique Gutierrez Floyd Landis Link to comment Share on other sites More sharing options...
linnega Posted September 18, 2006 Share Not sure about that list Cruxie - Hamilton, Heras, Millar, Basso and Landis did not produce extraordinary results for the races they were riding as they were the favourites in the events they were racing. Rumsas, Perez and Guti certainly came out of nowhere (and disappeared as quickly). Bikemax, the question probably is, is 7w/kg the magic number that is not attainable without enhancement? Basso's numbers remember were average numbers for the entire ascent, most of which he spent behind teammates before launching attacks that no one could follow.

widget Posted September 18, 2006 Share Yep, crux I agree. Bikemax, theres no other real data given by Pro Cycling except to say that "Bassos performance was not humanly possible given his physical potential"! So perhaps he is lighter 65kgs? or he can not normally achieve these stats constantly over 6 days of mountain stages? I think a climb like Alp D Huez is quick (well relitively) so achieving a high watt output over a short period is acceptable, but from what I can understand from the editorial is that this kind of output is not repeatable over 6 days over 6 mountain top finishes - which seems logical to me - no matter how good an athlete is there is a maximum human point which is not normal to exceed. Perhaps if you read the article in its entirity, you could glean a bit more from it??Perhaps I am missing something?? If you like, I will scan it in and copy you in - save you buying the mag unless of course you want to? widget2006-09-18 09:08:06 Link to comment Share on other sites More sharing options...
GoLefty!! Posted September 18, 2006 Share That Article does not really tell us much except that the Doc's think that 7Wper Kg is the maximum a cyclsit can produce.What about the mental factor? The truth is that the quacks know very little about the brain's influence on human performance and ophyscial recovery but they have to create the impression of authority so that a standard can be set. Look at EPO levels in the blood stream. They say 50% is a maximum yet there are riders out there with naturally higher levels... to sa that Basso's watt output for his build is beyond his phycial capability is probably only correct with a 90% confidence level and thats not good enough for a guilty verdict.

I remember thinking at the time that it was a bit sensationalist as the figures were just not that high (Landis was pulling ~370-390w up the final climb of his epic stage win and this after a shocking day the previous stage) I checked his profile and he is 70kg apparently. Repeatability, well if you have the form and you are getting recovered then it is possible to repeat high power output over a week or so - we see it fairly regularly in the mountains at the tour. Alpe D'Huez is actually about a 40 min climb (38 min record I beleive) and the power outputs up there were ~440-460 for the top guys. Power will obviously reduce over time (duration) but we usually use the 60 min power as a guideline (FTP) and it is this figure that 6.5 - 7w/kg is the magic number. I think that this is within his ability (maybe chemically aided) as it is also likely that the 400+w figure was not for the entire climb. Link to comment Share on other sites More sharing options...

Basso's numbers remember were average numbers for the entire ascent, most of which he spent behind teammates before launching attacks that no one could follow.[/quote] My gut feel is that those numbers are very unlikely to be attainable without "help" I have seen figures of ~5-5.2 w/kg from very good amateurs and these guys are flying.. Top TT riders like Michael Hutchence in the UK can sustain ~5.7w/kg Only supposition though.. Link to comment Share on other sites More sharing options...
BikeMax Posted September 18, 2006 Share Developing these ideas further, Antoine Vayer has provided some concrete examples, Knowing the physiological facts of Lance Armstrong (1.77m, 71 kg, (his weight during the Tour de France,) combined with the results recorded by the SRM, it is possible to measure the power output of the rider. "Take the climb of Alpe D'Huez, a climb of 13.8 KM at an average inclination of 8.11%. Take into account the parameters already indicated with the race conditions that sort them selves out into four categories: 1. The solitary victories from attacks which began at the foot of the climb (Armstrong in 2001, Marco Pantani in 1994, Lucho Herrera in 1987.) 2. The solitary attacks which began toward the summit. 3. The victories which emanated from groups which escaped before they arrived at the Alpe D'Huez. 4. Those that were acquired as the result of a sprint from a little group. This example took place in the years before EPO, or in the first years of EPO. According to him, the "extraordinary" are the riders who developed wattage in excess of 450 watts, with attacks at the bottom of the mountain. That would be the case with Marco Pantani, who realized a record time of 37 minutes 15 seconds after having toiled through an Alpine stage. Even without a bold attack in its first switch backs, Alpe D'Huez requires, in a climb of 41 minutes 20 seconds @ 20 km/hour, a development of 400 watts fpr a rider of 70 kg. David Moncoutie on a good day could get there. The record to beat is 36 minutes 50 seconds, established by Marco Pantani in 1995, at an average of 22.48 km/hr, having developed an average of 461 watts after having crossed the Madeleine and Croix de Fer passes. Lance Armstrong lays claim to the fifth best time (the three best were achieved by Pantani, the fourth by Ullrich) in 2001 in 38 minutes 5 seconds, at 21.74 kh/hr. for an averagee of 442 watts, after having crossed the Madeleine and Glandon passes."

BikeMax Posted September 18, 2006 Share More..(don;t read this Jason ) explains Antoine Vayer: "The VO2 max of the American, otherwise known as theblood's oxygen consumption. As always, our foundation is the known physicalcharacteristics of the rider- 1.77m, 71 kg in weight, bicycle weight of 8kg, air resistance, the route's profile etc. That day, Lance Armstrong wasgiven a time of 1 hour 8 minute and 36 seconds. In order to achieve thattime, he would have needed a V02 max of 89-90. I have worked with thephysical parameters given by half of the members of the Festina team intheir great era, that of EPO to be precise. EPO, more than any other oxygentransporter in the blood, reduced the importance of other physiologicalcharacteristics that would have been important to a rider. And LanceArmstrong did even better than that, for during the eighth stage, he had tomaintain an average power output of 450 watts. If we consider an index ofendurance corresponding to that of the best athletes in the world, these 450watts, which he maintained for one hour, corresponds to a VO2 max of 89, thestandard being a sprinter who is at 100% of his maximum over a distance of100m. In the discipline of track and field, if he had been a quarter miler,he would have been able to run 125 quarters at practically the same level ashe ran the first. To be always at your maximum, without suffering, isunthinkable. His performances are unreal." Link to comment Share on other sites More sharing options...
Cruxpearl Posted September 18, 2006 Share Not sure about that list Cruxie - Hamilton' date=' Heras, Millar, Basso and Landis did not produce extraordinary results for the races they were riding as they were the favourites in the events they were racing.[/quote'] Have to disagree slightly Linnega, Yep some of them were favorites for some of the races, but stil produced extraordinary rides in stages of those races, eg. Heras was favorite for the Vuelta true, but after his fall and being down on Menchov, rode an extraordinary stage, to get the yersey back and then not being known as a supreme timetrialist, riding the second fastest timetrial ever... subsequintly being busted for EPO.Basso was strong the year before, but at Giro, he was really playing with the others, producing crushing rides day after day... promting Simoni's remark of an "extraterrestrial" performanceLandis's 17th stage ride was also (IMHO) superhuman, even the other team managers didn't think that he would be able to sustain that effort & pace for the duration of the stage. And then of course his abnormal test result was for exactly that specific stage... All in all it just does not add up to a clean ride!!!

Back to the topic - Mr. BASSO and his GIRO efforts, anyone notice how easy it seemed for him to ride away from the competition? If you had to analyze his performance based on his external appearance without a reference to the other riders dropping back, he does not seem to be taking major strain OR look like someone achieving a superhuman effort, imo and with hindsight that is SUSPECT. Perhaps he had training from the Dali Lama's Schoolofrelaxationwhileunderextremeduress? Link to comment Share on other sites More sharing options...
linnega Posted September 18, 2006 Share Cruxie - I understand the cynicism, but I think there needs to be some level of giving the benefit of doubt to the riders. On your list, I am not saying that they deserve the benefit of the doubt, but that is only after other evidence has come to light that supports the suspicion. If you were to suspect every performance, you would have to question Boonen's dominance last year in the Spring classics, and Valverde's Fleche - Liege double, or what about Voigts superhuman performance in the Tour of Germany, and semi-classics around the same time. What about Bettini's ride in Zurich Metzgete last year in the rain, or Cancellara's ability to ride everyone off his wheel in Roubaix this year. Cycling is made up of superhuman performances - some less believeable than others granted - but we really need to not over anlyse every performance or automatically believe the performance is tainted because it was great. It is for that reason that I don't believe Basso owes Simoni any apology. Whether Basso did or didn't take anything, the fact that Simoni had no evidence other than getting beaten by a stronger (enhanced or not he was stronger - just like LA) rider is not reason enough to say what he said. If he some evidence that would be different, but he did not, so he was out of line and appropriately reprimanded. Swiss - I think Basso's expression is deceptive. That easy grin is actually a grimace. Granted he was superior at the Giro, but then so was Lance at every Tour he won. He never looked like he was struggling - except when he was lieing.

epoh Posted September 19, 2006 Share Dr. Michele Ferrari's Comments - 53x12.com ../img/spacer.gif Giro d' Italia 2006 - first part By: Michele Ferrari Published: 22 May 2006 At the Giro d? Italia, absolute domination of Ivan Basso on all his rivals. Afterthe victory in the TTT, Ivan strongly climbed over the Maielletta (940mof difference in height, gradient of 8.4%) in 31?48?, expressing a VAMof 1775m/h.Paolo Savoldelli, in rather evident respiratory troubles, climbed at 1642 m/h, that is about 8% slower than Ivan. Inthe ITT a few days after, Basso rode the flat 50km at an average speedof 50.6 km/h, Savoldelli at 49.9km/h: supposing a similar aerodynamicefficiency, the difference in power output is about 3% in favor toBasso. On the tough Colle di San Carlo (10.5km at 9.8%) Ivanbettered himself: VAM = 1820m/h, equal to 6.27 w/kg, notwithstandingthe rainy conditions and the almost 2000m of altitude.Paolo lost more than 3 minutes, with a VAM of 1670 m/h (5.75 w/kg), approximately 9% slower than his rival. SinceSavoldelli conceded an additional 5-6% in climbing performance, we candeduce a difference in body weight between the 2 riders of about 4 kg. Ifthis is the case, imagining a weight of 67kg for Ivan Basso, hisaverage power output on the climb was 420 watts. Savoldelli, with aweight of 71 kg, pushed 408 watts. A difference of 2.9% that would confirm the result we saw in the Time Trial. Link to comment Share on other sites More sharing options...
