The folks claiming max HR isn't important, do they know what they're talking about? If so, I'd listen to them. Maybe ask questions where things don't quite make sense.

The power meter data from the Ventoux video would have been recorded from a stages unit. As such, any motor used to drive the crank axle or a rim or any other known method of motorised doping would not have contributed to the power reading from the Stages. i.e the Stages would have demonstrated a lower power output than required to perform the work of climbing at the rate recorded. As it did not, there can clearly be no motor.

Is it really John? I mean dude comes into a place where doping talk is rampant. You can't expect everyone to just march the goose step and fall in line can you?ScienceIsCool said:sniper said:Of course.Jeroen Swart said:...
I think the key point that needs to be addressed is that physiological testing does not confirm or refute the use of prohibited substances.
You need specific evidence relating to those and all these vague circumstantial bits of evidence only serve to muddy the water.
One thing we did clarify with the testing is that the performances we have seen in the races are within the limits of normal human abilities. Which puts to rest all these inferences that a performance was "mutant" or otherwise.
Once again, whether it was done cleanly or not is not established by the climbing rate or the physiological testing. Neither will answer that question.
We need at least two or more data points for one variable, so that we can start comparing.
That's why The Call was for multiple tests to be carried out throughout the season. Not one isolated test.
(see the quote in my previous post)
That's why the dodgy Fax (of which apparently there is no original) was quickly muffled into the Esquire article.
That's why the missing max HR was such a pity.
And that's, in the end, why I said this job had "amateurism" written all over it.
You're not listening to Jeroen, are you? And to publicly call someone's professional work amateur is quite low. Especially since it was nothing of the sort.

I question the loyalty of the person as I do not know anything about his profession. I just know from my perspective he seems to be part of the "club".

sniper said:John - a couple of things for you to consider:
If I am asked to do a scientific piece of work and asked to offer my opinion on my work in comparison to another data set, I am professionally beholden to consider all of that other data set.
If I cherry pick only material that suits the client's reason for seeking my services but ignored other parts of that data, I could open myself up for accusations of bias and lack of professionalism.
First off:
Have you ever tested an elite cyclist who has a body fat of 16.9%?
I presume the answer is setting alarm bells off in your mind.
Then consider what the body type is of a person with c. 17% body fat compared with contemporary pictures of Chris Froome. OK that would require the most modest piece of detective work, and maybe searching "chris froome 2007" images was not something Jeroen wanted to contemplate.
I did do the search and I can't find any photo that looks like he had any kind of fat to loose.
Much more the profile of a 8-10% body fat person in the pictures I can see.
As it happens, that judgement coincides with what we know about the Chris Froome from 2007:
(a) he'd been racing several races quite shortly before the testing, so he was trained;
(b) in the book Vavafroome (excerpts of which you can find in google books), Johnny Lee Augustyn alleges that Froome had always been very much into diet, always watched his food, etc.. He's talking about the 2007-8 period there.
But fair enough, the fat percentage shall remain a subjective judgement. So let's not get hung up on that and instead let's get back to facts and the numbers before us.
Here's one right up your street.
BMI = mass ÷ height²
So if I use the data from the 2007 fax, I get the number 21.85.
Were I scientifically illiterate, I would round to 21.
But if I had any sort of rudimentary scientific/engineering/mathematical skills, I would round to 22.
Please tell me: why is it rounded to 21 on the fax?
One possible hypothesis as to why it was rounded the way it was rounded is because the person doing the rounding was as I described above, amateurish.
What to make of Jeroen not noticing the incorrect BMI/weight ratio and, when made aware of it, discarding it as an insignificant rounding issue, is another question.

What are the limits of normal human abilities? How are these determined? Does the testing assume that his test performance is the same as what we've seen in races or does it only establish his abilities at the time tested? I assume you are suggesting the former but I would like that explained as it seems clear with doping possibly involved these conclusions seem premature. If the latter than how does this testing put anything "to rest'?
Once again, whether it was done cleanly or not is not established by the climbing rate or the physiological testing. Neither will answer that question.
Did not Froome/Sky engage i this exercise to show that Froome was clean? No question this test wasn't going to establish that. If that is true, doesn't your reputation become entangled with a fairly dodgy and transparently false PR exercise? Would that not explain some of the reaction you're getting here, informed or otherwise?

In that post I describe why there's some "who cares" about the fax.
replace [can say] with [should have said], and I agree.I also try to explain why there's not much Jeroen can say about it.
It's not like it was published anywhere.

Good post + questions, Red.

nitpicking and dodging.

How did he get from 2007 to 2011. Or more accurately Tour of Poland to Vuelta.

Science is cool, John.
But the fax makes a mockery of it.
Have you even seen the evidence or did you just chime in to toss Jeroen a life line? If the latter, fair enough. If the former, feel free to PM me.
You and Hog are piling on accusations which completely ignore the reality of what happened. Don't like the fax? Disregard it. Now go back and read through the description of the testing, who was involved, and what their relationships are. There's a lot of good explanations there.
Things like saying that the testing was bogus because the hooked up a bike to a wind trainer are, quite frankly, ignorant. Instead, you could have asked about the test setup. How was power measured? What equipment was used? How did you calibrate? <--- Pssst. That was the type of info that made Coyle's paper so embarrassing.
Personally, I think it's always wise to challenge the methods, analysis and conclusions in a paper. You have access to the author, which is very rare. Why don't you make good use of it? To start, do you have a copy of the paper? Maybe arrange to get one if you can. I bet Dr. Swart would provide one.
I'd also ignore the magazine (Esquire?) article. Anything in that article is the responsibility of the editor. While it might not contain any factual errors, the article could never be as complete as the paper it's reporting.
