Don't be so quick to say you agree with someone when the agreement is only skin deep then. Also, I could do without the condescension from you. I think it is pretty clear to a neutral observer that, while admittedly imperfect, I have a better grasp of the scientific part of this than you do. you've coached yourself to some decent permformances so you must know something about training but for the love of god please have some humility about the science or you will never grow from where you are now. Ask yourself when's the last time you admitted you wrong Jon?
About altitude and blood plasma, we have to draw a distinction between short and long term adaptations. It's from Renato's posts about training his runners that I got the idea that elite runners training at altitude increase plasma faster than they increase hematocrit. After the weekend I'll search through the forums and paste in the posts I'm thinking of. Certainly this does not have to happen when training at altitude. it's the basis for his argument for why EPO shouldn't work in East Africans born, raised and trained correctly at altitude. I happen to think his argument points the other way. That's the kernel of this thread.
