As and when self-improvement, which has already been part of our society for thousands of years, will become more and more advanced, there will eventually arise competitive sports in which the use of supplements ("dope") is no longer secretly done by some of the athletes but openly by all of them, as well as other forms of enhancement such as genetic and robotic. The use of these supplements will be supervised by doctors, however, and supplements which could be harmful to the athlete could be either forbidden (so that, unfortunately, there would still be illegal dope) or advised against. This supervision would have to be very strict, much like the dope tests today, so that there would be no risk of an overenthusiastic athlete experiment recklessly with the wrong enhancements, that is to say, enhancements known or unknown to be dangerous.

This would also be interesting in that it would allow researchers to find the best way of improving the human body's performance. That doesn't mean the athletes would be used as test animals for new enhancements, but that once was known that they are safe, they could try to find the ideal combination of enhancements. The doctors would place a limit on the number of enhancements, so that they would not harm their health, depending strongly on the nature of the enhancements.

Because this enhancement is a complicated process, the sports would be as much a cognitive sport to the doctors (or the athletes, in case they also occupy them with this), as a physical sport to the athletes.
