I have been of the opinion for awhile that a large ratio of international athletes in any sports involving strength or endurance to a strong degree are doing some kind of doping. I believe the doping testing across sport is stronger now so the drugs athletes use are not as heavy as the 80s, hence why all the female track records are still from the 80s, and the 70s and 80s East German swim records didnt begin to fall until the 2000s. However a large percentage of international athletes still dope, just with less powerful or sneakier drugs than before.
