I don't know. Epo increases the number of red blood cells. Red blood cells carry oxygen. Oxygen is needed to stave off lactic acidosis. The more supply of O's you have, the longer it takes to go anaerobic. So, in essence, that's increasing 'endurance', right? Perhaps I'm simplifying the process?
Your absolutely correct. And "ex-runner" doesn't know what he's talking about. In this study, increased O2 transport as a result of RBC infusion improved 10k running times to the tune of 1 minute & 9 seconds, on average.
These runners didn't change their training, mileage, intensity, etc. Just the increase in RBCs provided more O2 to the working muscles which increased endurance/aerobic capacity and improved 10k times.

I clearly wrote it helps you get more out of your aerobic system. I never said EPO doesn't work.
I am sure runners doing the 10k trained aerobically, and so they already have the vascularisation, stroke volume and mitochondrial adaptations etc. to take advantage of more red blood cells/oxygen.
Giving EPO to someone that doesn't train aerobically wouldn't help nearly as much.
I do not believe you can give EPO to an elite miler to substitute for aerobic training. They can't just do speed training and take EPO to compensate as the poster I was replying to suggested.
That was my only point.
Nothing to do with highly trained endurance runners in the 10km. Nothing to do with EPO not working.
