I understand that it's possible for there to be drugs that help gymnasts and skaters. But because these athletes' excellence doesn't depend solely on "faster, higher, stronger," there may (I hope and pray) be less incentive for their use. After all, increased size and muscle mass isn't in and of itself an advantage to skaters. In fact it's a disadvantage, even with male partners in pairs. If you look like a stiff linebacker hefting your partner, you could lose points. In terms of the substances that speed up healing, one that I know of, steroids, actually endangers the area of injury in the long term, so it would be counter-productive. I hope that the athletes reason that way, too.
