Q: No doubt your superhuman performances will bring whispers of steroids and human-growth hormone. How often and thoroughly are tests run on swimmers? James Kelly, SPRINGFIELD, MO.

A: I get tested at least twice a month. I can definitely speak for myself–the results are the results. They’re proof that I’m clean, and that’s just how it is.

Q: How do you explain that you (and other swimmers) quite often smash world records by half a second, sometimes even one or two seconds, while world records in track and field hold much longer and are beaten by narrow margins? Jeremie Clevy, PARIS

A: They are two totally different sports, first of all. But I think in swimming there are so many little things you can change that really do make a big difference in the end. We’re able to go back to the drawing board and work on small things that cause significant differences when we are racing. If you think about it, we only have one big meet a year, so we train for that one big meet.
