Pistorius might not be allowed in Olympics

The prosthetic legs double-amputee sprinter Oscar Pistorius uses provide less air resistance than normal legs, the IAAF said Monday.

Pistorius, who wears curved, carbon-fiber prosthetic legs, finished second in Rome on Friday and last against elite able-bodied athletes at the British Grand Prix on Sunday. He hopes to compete at the 2008 Beijing Olympics.

“The guy Oscar beat on Friday – the stride length was the same, but the speed through the air was slower for the able-bodied guy,” IAAF spokesman Nick Davies said.

Pistorius ran 46.90 seconds in the 400 in Rome. To make next year’s Olympics, he would have to run a 46.3.
