Yes you are correct. Just because the physiological actions of testosterone on the human body are well known does not automatically mean that it enhances recovery. But the problem is that it is virtually impossible to conduct a study in elite athletes because it is a banned substance. All you can do is use well trained subjects (but not professional athletes). In the absence of literature examining specifically what you're asking, it is entirely possible to make an assumption that doping with testosterone aids performance in cycling on the basis of the existing literature and the anecdotal evidence that is has been in common use for 10-20yrs in cycling. If it didn't work, they would have have figured it out a long time ago and stopped wasting a LOT of money.slcbiker said:There is a difference between theoretical physiology and proof that something works or doesn't work and how much effect it has. That's why people do studies. For instance:
Hoogeveen and Zonderland in the International Journal of Sports Medicine. "Relationships between testosterone, cortisol and performance in professional cyclists".
From the abstract:
"These results suggest that in endurance trained cyclists, decreased testosterone levels, increased cortisol levels and a decreased testosterone: cortisol ratio does not automatically lead to a decrease in performance or a state of overtraining."
Gosh, you know what, you're right, anyone can indeed go into PubMed.
Good to see you follow the link to pubmed! Many others would not have even bothered!! The Hoogeveen study isn't particularly useful though with respect to the current thread topic because it did not examine exogenous testosterone administration during a period of intensified training. What it reveals is that the test/cortisol ratio is a variable that requires very strict measurement control if it is to be of any use in monitoring accumulated athlete fatigue.
