Several of these would be charged in connection with doping activities or would continue working as sports scientists after leaving the Institute. The most well known is Michele Ferrari who worked with Conconi during the 1980s until the mid-1990s. He took care of some well-known pro cyclists, although only few of them have actually been found guilty of doping offenses. A possible cause is the gap between development of doping and the means to trace the use in sportsmen. However, in the light of recent revelations, this list may well point in the direction of certain medicinal networks, notably in Italy, but not of proven doping networks.
