The length of running blades used by athletes for the Paralympics is worked out using a complex formula based on the proportions of the body.
But Pistorius also competes in the able-bodied competition and if he changes the length of blades he could find himself disqualified.
Craig Spence from the International Paralympic Committee explained to Alastair Stewart that he would have to keep the same blades to compete in both.
Team South Africa and SASCOC (South African Sports Confederation and Olympic Committee) have issued a statement welcoming Oscar Pistorius's apology for his initial reaction after the T44 200-metre track final last night:
According to analysis from The Science of Sport:
- In the first 100m, Pistorius took 49 steps (2.0m per stride), with 43 steps in the straight (2.3m per stride)
- However, Oliveira took shorter strides - 52 in the first 100m (1.92m each) and 46 in the second 100m (2.2m each)
Sport scientists have waded in to the row, pointing out that Oliveira took more steps to win the race.
