What will be interesting to see is if the purists will allow technological enhancements that are currently accepted, such as Gatorade.

As prosthetics engineering keeps improving, there is no doubt that engineers can come up with a better “running leg” than humans are born with. Such a prosthetic can be *highly* specialized for the event the athlete competes in. So maybe a “running leg” wouldn’t be great for daily living, but it might be GREAT for sprinting. Pistorius is a sprinter in fact, and his lower legs are made of carbon fibre — probably MUCH lighter than human legs and helped even more by the fact that the running shoe can be designed right into the prothetics. Low mass = low inertia and that lets a sprinter sprint *really* well. Additionally, the dimensions of the legs themselves can be redesigned away from the proportions of the normal human body to optimize them for sprinting — maybe a short “foot” and a long lower leg is best or maybe the reverse. No “able bodied” (!) runner has this knob to turn. The fact that Pistorius *never competed* in track events before 3 years ago and is now (nearly) Olympic caliber should tell you something.

And even if high tech prosthetics engineering isn’t yet quite up to biological legs, they will be sooner or later (ala Steve Austin – he could run 60 mph!). How do you draw the line in what is acceptable and what is not? It is best that they set the policy sooner rather than later. The worst thing would be to outlaw them after people start winning medals – there wind up being a whole slew of questionable “champions” that way.
