Now this is a remarkable change if you think about it. The "concentration" of testosterone and estrogen - estradiol is what really counts - changed by 24% from just one lifestyle change. Imagine what could happen as you pile on some of the other Testosterone Increasing Techniques and Estrogen Lowering Strategies that I have mentioned on the web site. There is no reason that you cannot dramatically improve your ratio of testosterone to estradiol (unless you happen to be training for the Olympics with a professional trainer).
In international athletic competition governed by the World Anti-Doping Agency (WADA), testosterone is specified as a banned substance on the Prohibited List of all illegal performance-enhancing substances. Testosterone is classed as an anabolic androgenic steroid, an illegal steroid that is intended to produce or facilitate male growth and physical characteristics in an athlete. Prior to the ascendancy of WADA in the late 1990s as the foremost drug regulatory agency in athletics, a number of notable world-class athletes had been the subject of positive testosterone tests, among them American sprinter Dennis Mitchell, American middle distance runner Mary Decker Slaney, and Dutch shot putter Erik de Bruin. Unlike other chemically produced performance-enhancing substances, testosterone is present in the body of all athletes in varying degrees. Testosterone testing is based on whether the hormone appears to be present in an unnatural amount, beyond the range that would typically be expected in that person. The WADA standard for the testosterone range is generally where the amount of testosterone present through testing is greater than 4:1 ratio to the expected levels; at those levels, a positive drug test is deemed to have resulted.
For that reason, I believe that the IAAF policy around an upper limit was the best solution, for now. It’s not perfect, and anyone who claims it’s simply about testosterone is wrong. But it’s a better place to be than where the sport is, and that’s my opinion. I cannot acknowledge the women’s 800m as a credible event as a result, but I hope that Semenya (and a few others) go out and run 1:52, and I wish she would run and win the 400m too. Sometimes people need to be struck between the eyes to see the obvious.
