When Oscar Pistorius calls himself "the fastest man on no legs," it's not an exageration: In May, the 20-year-old sprinter from South Africa won the 100- and 200-meter events at the Paralympic World Cup in London, an international competition for disabled athletes. Now he hopes to become the first amputee runner to compete in the Olympics, which will be held in Beijing in August 2008.

But Pistorius has faced resistance from track-and-field officials who say that his high-tech prosthetic limbs may give him an unfair advantage over sprinters using their natural legs. Before Pistorius can realize his Olympic dream, experts will have to determine whether his prosthetics make him "too-abled."

Due to severe deformities in both legs and feet, Pistorius's legs were amputated below the knee when he was 11 months old. Having worn prosthetics since infancy, Pistorius did not have to adjust to artificial legs after he began competing. He sprints on a pair of "Cheetahs"--J-shaped blades made of carbon fiber.

"I don't see myself as disabled," says Pistorius, a former rugby and water-polo player. "There's nothing I can't do that able-bodied athletes can do."

In July, Pistorius competed in the 400 meters against several Olympic medalists at a meet in Sheffield, England. The winner, Angelo Taylor of the U.S., finished in 45.25 seconds. Pistorius finished in 47.65 seconds--well short of his personal best of 46.56--and was later disqualified for running out of his lane. Speaking of his competition, Pistorius says, "I have a long, long way to go before I get to their level."

'THE PURITY OF THE SPORT'

The fact that Pistorius is blurring the lines between "abled" and disabled raises questions: What should an athlete look like? Should limits be placed on technology? Would it change the nature of sports if athletes using artificial limbs could outperform top athletes using their natural limbs?

For the past six months, the International Association of Athletics Federations (I.A.A.E)--the world governing body of track and field has been trying to decide whether Pistorius should be allowed to compete against able-bodied runners. In March, the association passed a rule barring any runner using artificial aids, disqualifying Pistorius from events that it sanctions. "With all due respect, we cannot accept something that provides advantages," said an I.A.A.E. official. "It affects the purity of sport. Next will be another device where people...
