I heard that 9 athletes have been caught doping; I wondered if any were cyclists...no An article went on to say, "The biological passport measures changes in an athlete’s blood profile and is already used in professional cycling. It will be utilized in testing in track and field, swimming, cycling, rowing, modern pentathlon and triathlon at the Olympics, the World Anti-Doping Agency announced in a news conference at Olympic Park". Two things struck me. Biological passport measures have been in cycling for some time (years?). But many sports have chosen not to bother with it; why not? When reports are made of cyclists doping, no mention is made that cycling is pioneering new measures? Cycling gets dragged through the mud time and time again but it seems that other sports have their heads in the sand. But of course, who from these 6 sports are going to put in an inexplicably poor performance! Or take a chance?
