Pistorius waits on Olympic news

Pistorius is the world record holder in three Paralympic events

Double amputee sprinter Oscar Pistorius is set to hear within the next three weeks whether he can compete at this summer's Olympic Games in Beijing.

The South African finished his two-day appeal at the Court of Arbitration for Sport in Lausanne on Wednesday.

In January, athletics' governing body the IAAF banned him from able-bodied events.

It claimed the 21-year-old's prosthetic limbs give him an unfair advantage, but he disagrees.

"We're hoping for a very quick decision," said his lawyer Jeffrey Kessler.

"Oscar is very happy to finally have had his case heard. He has great faith in the tribunal and is now hoping for a quick and fair decision."

The IAAF ruling was based on studies it commissioned by German professor Gert-Peter Brueggemann.

He concluded that the prosthetic limbs gave Pistorius an unfair advantage because he uses 25% less energy than an able-bodied runner.

Pistorius has subsequently undergone tests in the US in an attempt to prove his case.

Ahead of the hearing he said: "This case is important not just to me, but to all disabled persons who just ask for the chance to compete fairly on the sporting field with able-bodied athletes."

If the IAAF decision is overturned, Pistorius would still need to qualify for the South African team to race at the Beijing Olympics.

The athlete said his schedule would be seriously affected by the ruling because about 80% of his races are able-bodied events.

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.

He began running competitively four years ago to treat a rugby injury, and nine months later won the 200m at the 2004 Paralympic Games in Athens.

Nicknamed the "Blade Runner," Pistorius has set world records in the 100m, 200m and 400m in Paralympic events.

He finished second in the 400m at the South African national championships last year against able-bodied runners.
