Good point. My arguments were based solely off of training effects; I failed to consider the genetic component completely. It's to bad there is not a whole bunch of twins out there (one a world class lifter and the other a world class athlete in another sport). Percentage-wise, how much would you say genetics influences the outcome of a performance athlete? It's an area of fitness I am pretty much unfamiliar with. Besides the purely genetic factor, we would probably have to take into account the fact that naturally stronger people would likely gravitate towards O-lifting as opposed to people not so gifted (who would then pursue other interests, like underwater basket weaving or whatever).
