Increased knowledge can yeild more accurate judgements, but only if interpreted correctly.<BR/><BR/>Several teams have funded their own version of the bio passport system. Again, I find that an excellent (perhaps the best?) insurance policy to defend their riders against bogus AAF's. <BR/><BR/>The only indication I've seen that the bio passport system might represent an era where the rules are better respected is that the name(s) of suspected athlete(s0 has not been leaked. That give me some small hope they will follow through on the rest of the package to actually make it work as advertised. Again, time will tell. I, and many others, will be watching.Unknownhttps://www.blogger.com/profile/09427604865634964926noreply@blogger.comtag:blogger.com,1999:blog-31819641.post-34810342797477936962008-05-06T18:45:00.000-07:002008-05-06T18:45:00.000-07:00"So what would happen if you found 850 non-athlete...<I>"So what would happen if you found 850 non-athletes with no reason to dope, and tested them 2100 times? Statistically speaking, are you likely to find zero anomalous measurements? That would be almost impossible. So how many anomalous readings to you expect to find?"</I><BR/><BR/>And how many more would you find if you subjected them to the kinds of physical and mental stresses and goofball diet of a hard training or in-competition endurance athelete? The point being that it is not valid to assume that you'll measure the same things in elite athletes that you do in non-athletes (e.g. a bunch of med students at UCLA, as in one of the big studies on the IRMS test for exogeneous testosterone).<BR/><BR/>But then again, anti-doping is as much about poltics, zealotry and commercialism as it is about science. I guess to some that justifies cutting some scientific corners.Cubhttps://www.blogger.com/profile/13165830621857799735noreply@blogger.comtag:blogger.com,1999:blog-31819641.post-64809287136412270062008-05-06T18:05:00.000-07:002008-05-06T18:05:00.000-07:00Lies, damn lies, and statistics. Measures of cent...Lies, damn lies, and statistics. Measures of central tendencies can be manipulated by mathematical models to achieve a desired result. Even then this does not account for individual differences within a population. The "biological passport" science is incomplete and those who refuse to admit that "false positives" are impossible because of anti-doping dogma will destroy the athletic careers of innocent athletes.velovortmaxhttps://www.blogger.com/profile/06282207009021242082noreply@blogger.comtag:blogger.com,1999:blog-31819641.post-51164673825639248312008-05-06T18:01:00.000-07:002008-05-06T18:01:00.000-07:00This comment has been removed by the author.velovortmaxhttps://www.blogger.com/profile/06282207009021242082noreply@blogger.com
