Testosterone levels usually goes down after more than one hour of hard physical exertion, to rebound slowly during the next 12-24 hours.
During the tour with many days in row with all out effort, testosterone levels go down quite dramatically over the three weeks, as the recovery time is not enough to get testorenone levels back to base levels.
That is why, a testosterone shot this late in the tour would be particularly beneficial.
Cheers.
Thanks for the clarification.....I had a 50/50 chance of getting it correct, however, do all (100%) males respond in such a manner?
I read through the article where Landis says he's innocent.
Evidently, if the article is accurate, a bad test is a ratio greater than 4 to 1, with 1 to 1 being the "most likely" natural ratio.
It seems to me the only way to get a good baseline is to test a lot of people at random and check that baseline against a broad spectrum of athletes, or, perhaps, soldiers.
From the way the article is written, it leads me to believe there may be some holes in the statistical method by which the "normal" ratio is determined.
I bring this up, because the term "most likely" ratio leads me to think there isn't a good baseline to work from.
Given the pre-race disqualifications of Basso et al, wouldn't a high-profile rider like Landis have to be certifiably insane to use illegal substances during the TDF?
