It wouldn't be classed as doping but some of the Columbians (Quintana etc) grew up cycling at high altitude so that could be a factor.

Transfusions must be a more extreme increase in blood cells than high altitude training. Im more just curious if anyone has failed because of high altitude training. More or less just thinking out loud at this point haha.

They are transfusing bags of pRBCs (packed red blood cells), which have been separated from other aspects of your blood. With high altitude training/blood doping it is a similar idea. You train at altitude, which naturally increases your red blood cells. You then draw/collect your blood after training at altitude for a while. Back at sea level your body will kill off the excess red blood cells as you don't need them, but you can then transfuse your blood you saved from the altitude to boost your RBC count.

dude...:
for anyone interested, sheldon brown (rip) wrote a thing about biopace and using it with fixed gear setups (which is kind of similar to if you were running it single speed on a bmx.

My roadbike that i found on a verge has biopace chainrings on it but i never realy ride it enough to notice the effect
