When the amputee is barred from the Olympics because his prosthetic legs give him an advantage...

... then you know how wonderful technology is. But too bad for Oscar Pistorius.

[German professor Gert-Peter] Brueggemann found that Pistorius was able to run at the same speed as able bodied runners on about a quarter less energy. He found that once the runners hit a certain stride, athletes with artificial limbs needed less additional energy than other athletes.

The professor found that the returned energy ''from the prosthetic blade is close to three times higher than with the human ankle joint in maximum sprinting.''...

Pistorius was born without fibulas -- the long, thin outer bone between the knee and ankle -- and was 11 months old when his legs were amputated below the knee.
