Can some prosthetics give athletes an benefit
MARK COLVIN: After by far the most stunning upset on the Paralympics, queries are being asked about the way prosthetics can influence a disabled athlete's performance. It is reminiscent with the rows in Olympic swimming over quickly suits inside the pool.
The man referred to as the 'blade runner', South African sprinter Oscar Pistorius,Cheap Christian Louboutin, has lashed out in the man who beat him. Pistorius says the blades worn by Brazil's Alan Oliveira gave him an unfair benefit.
MARTIN CUDDIHY: When Jamaican Sprinter Usain Bolt won gold in London, nobody stated he had an unfair advantage because of his height. That's one of the key variations amongst the Olympics and the Paralympics.
In the Paralympics, an athlete can efficiently modify a part or components of their physique to alter their athletic efficiency. Stephen Wilson can be a former Paralympic sprinter.
STEPHEN WILSON: Theoretically we would say that, of course,Cheap Ray Ban Sunglasses, if you have longer limbs, your stride length increases. So if you're able to maintain the same stride frequency using a longer stride length, you happen to be going to run considerably faster.
MARTIN CUDDIHY: That is the complaint of Oscar Pistorius. The planet record holder won the 200 metre title in both Athens and Beijing. He was leading the final in London,Ray Ban Aviator 3025, but with 30 metres to go, was run down by Brazil's Alan Oliveira. Just after his loss, the South African was not gracious.
OSCAR PISTORIUS: The guy's legs are unbelievably extended. Not taking away from Alan's overall performance - he's an excellent athlete - but,Cheap Ray Ban Aviator Sunglasses Uk, you understand,Christian Louboutin Uk Sale, the guys, when we did the measuring inside the call rooms, a year ago go these guys had been over here; they are a great deal taller and also you can not compete stride length, you saw how far he came back, so?yeah, we're not racing inside a fair race, yeah, but um?I gave my most desirable, had a fantastic night.
MARTIN CUDDIHY: Stephen Wilson has won 3 gold medals, two silvers, plus a bronze. He's now a teacher, retired from athletics, but still believes competition is fairer on able-bodied athletes in the Olympics.
STEPHEN WILSON: I think at the Olympics, and I think, you know, is it it is an even playing field? I think in terms of Paralympic athletes, these places grow to be, of benefit and disadvantage, turn out to be far simpler to find out, and we do query, you understand, is there fairness?
MARTIN CUDDIHY: So you don't believe it really is probable to have a entirely even field at the Paralympics? Uh?it is easy to when it comes to disability in some events. Sprinting's actually about stride frequency and stride length. If you're growing your stride length, well, you happen to be taking care of certainly one of these categories, and T43s have the capacity to truly manipulate that.
MARTIN CUDDIHY: The vice-president in the Australian Orthotic Prosthetic Association is Harvey Blackney. He says the man who beat Oscar Pistorius,Ray Ban Prescription Sunglasses Uk, Alan Oliveira, seems taller than he could be if he didn't have prosthetic legs.
HARVEY BLACKNEY: Yeah he looked about among 70 and 80 millimetres higher in that segment amongst his knee joint plus the ground.
MARTIN CUDDIHY: So Oscar Pistorius includes a genuine grievance?
HARVEY BLACKNEY: Oh, I feel it's a valid claim.
MARTIN CUDDIHY: The International Paralympic Committee says all the athletes and their prosthetics were checked before the race, and all had been approved for competition. The majority of the sprinters use a prosthesis referred to as a 'cheetah foot'. It acts like a coiled spring, reproducing about 95 per cent with the energy a human foot would.
Cameron Ward is actually a prosthetist working at the Paralympic Games. He says it would be fairer if they all applied the exact same prosthetic, but it is pretty much impossible.
CAMERON WARD: Just about every prosthesis is fully custom-made to fit that distinct particular person, and each and every amputee's stump or residual limb is of totally different lengths, so the lengths amongst the end of their stump as well as the ground desires to be unique for everyone.
MARTIN CUDDIHY: He says you can get some parallels amongst the prosthetic debate, plus the debate regarding the unfair benefit supplied by some swimsuits.
CAMERON WARD: The point with prosthetics though is that these guys need to use them, so the swimmers can swim with out the swimsuits; the athletes can't run with no their prostheses, so it is just a little bit various in that regard, but sure, it's a technological debate, and I feel it's going to continue on for some time.
MARTIN CUDDIHY: Former Paralympian, Stephen Wilson, is hopeful the competition doesn't get distorted.
STEPHEN WILSON: I most certainly think that absolutely everyone desires a fair, a fair field. We would like to know that the right athlete's winning,Cheap Ray Bans, not the right manipulation of prosthetics.
