None received compensation for their research or participation in the hearing. The authors plan to submit the study to a peer-reviewed journal now that the legal case has been settled.
The scientific team was asked to evaluate the IAAFs initial claim that the Cheetah Flex-Foot prostheses (J-shaped, high-performance prostheses used for running) worn by Pistorius give him an advantage over able-bodied runners. The team concluded that the scientific evidence put forth by the IAAF investigation to ban Pistorius was fundamentally flawed. While an athletes performance in sprints of very short duration is determined almost entirely by mechanical factors, in races of longer duration, such as the 400m, performance depends on both mechanical and metabolic factors, said Herr, a bilateral amputee who heads the MIT Media Labs Biomechatronics research group.
Based on this performance link, the scientists refuted the IAAF findings on two major points: the speed-duration relationship and rates of metabolic energy expenditure.
Specifically, the scientists concluded that:
"Based on the data collected at Rice, the blades do not confer an enhanced ability to hold speed over a 400m race," Weyand said. "Nor does our research support the IAAF's claims of how the blades provide some sort of mechanical advantage for sprinting."
