I try to resume all your questions with quickly condensed reply, and without the goes to the physiology and sports science territory, the way everybody will understand and that HRE will continue to say "excellent post" Antonio. And yes, i promise not to debate Lydiard this time, that HRE could joke with me.
My answer to all your questions. I go by facts not by theories.
1/ACTUALLY WE GOT A GREAT HISTORIC ABOUT EPO CAUGHT IN DISTANCE RUNNERS, due to POSITIVE TESTS tests or just CONFESSION.
1/ the number of runners that were caught with EPO, while they do fantastic performances during the period of EPO take (and also more moderrn oxygen boost substances including blood doping) ARE SO MANY AT ANY LEVEL OF RUNNER CATEGORY and at ever level of competition, from local runs, to national runs, meetings, to world championship and olympics THAT IS IMPOSSIBLE THAT EPO DID HELP THEM, or during the run or help them to train more or better or just better recovery, somehow EPO DID HELP THEM TO PERFORMANCE BOOST. This is a fact and anyone that denies it is "deef and blind" to the drug and oxygen booster substances.
2/this said, ther´s always one part of the problem that Renato might be right. When he says that drug EPO namely) might have different effect in different individuals. This is similar to every kind od medicine substance, from one tea, to one vitamin, to EPO, and he is right when he says that all depends of the percent/dosage of the substance.
3/therefore, MY CONCLUSION. To take EPO is not a "sine qua non" condition to best performances, and also to take EPO DOESN`T GUARANTEE world records, wins, pbs, rich performances, since competition depends upon several factors - intrinsic and extrinsic and ther´s no drug that might replace poor training, or the run failure.
4/It´s Renato Canova that says that the kenyans got the same genetics and the same NDA (or ADN in english ?) that almost every other world population. therefore, if we take for granted what he says, EPO would work exactly the same as any other population. If it works or others, even for moroccans, will work or eats africans, if doesn´t work for kenyans would not work for Europeans, Americans or Asians in the condition that all did the same training.
I repeat, there were so many runners caught with EPO or that did confess that took EPO that it would be a fantasy to say that doesn´t work on top class runners. IT DID WORK ON THOSE WE KNOW.
Finnaly and one more time, once again. This debate is just pure theory and in part a wast of time. I prefer to debate learn and get some knowledge about distance training approach that doesn´t include doping. It´s illegal POINT.
ps- EPO works for cycling as well, this is an evidence since so many world top class cyclists did take EPO. The problem is that doesn´t work for boost performance directly , and at this point Renato says, or boost performance, it works by other kind of reasons. I will post why it works.
