Of course not...there's nothing to see here with these EPO/blood doping cheats running WRs, winning Olympic Gold, winning major marathon titles, winning European titles, etc. I forgot - you're the new authority now on EPO & blood doping effects with elites. My most humble apologies for ever suggesting that doping had anything to do with any of their achievements.
So what...top female distance runners were getting caught using EPO & blood doping (e.g., Shobukhova, Savinova, Dominguez, Graf, Ceplak, etc.). If it's all about androgens with the ladies, then why are they O2-vector doping? Since you're the new authority now...please explain this?
Yes...it's an experimental design study but the authors use the word "cohort" in both the abstract & text. And they are observing & analyzing data from the study...so what's with your nick-picking?
WTF again? It was a double-blinded crossover experimental study. So, doping expert; Why did the group when reinfused with RBCs experience a significant increase in Hct (over 10%) and run an average of about 69 seconds faster than when infused during the crossover with a placebo saline solution and no increase in Hct seen?
