Not having listened to the show, can you explain what is meant by "rebound effects"? Thanks -
Really you should listen, it's interesting, Mark Zeigler is well informed and is prepared to talk about what he knows.
Anyway, rebound effects are this; if you take something that mimics the action of one of your bodies systems, and then after a period of time you stop, it takes a while for your body to recover. You go from a surplus to a deficit, before settling down to normal. Effectively the ringing that will occur any feedback system that is not sufficiently well damped.
A classic example of this, that many could probably easily relate to, would be quitting smoking.
In the show Mark Zeigler is passing on the opinion of Victor Conte. He talks about what is allegedly referred to as "PCT" - post cycle therapy. This is described as reduction in your bodies production of testosterone after a period of taking steroids. The suggestion is then made that athletes will take something to "kick-start" their bodies testosterone production - in the case of LaShawn Merritt the products used were DHEA and Pregnenolone (allegedly). It is further alleged that these are products commonly used for PCT.
It is important to note that:
i) This doesn't have to be valid science, it just needs to be something that athletes believe will work.
ii) I don't want anyone pulling me up on the validity of the science because, hey, I'm just transcribing something for the benefit of someone who didn't want to listen to it themselves.
For those that do actually want to listen the relevant section starts at about 5.50, and you might also be interested in the bit at about 23mins about the masters cyclist who tested positive. Or all of it really, the whole show (49mins) is just packed full of good gossip about doping, and nothing else. I know I'm going to have another listen later.
