Oscar Pistorius' artificial limbs give him clear, major advantage for sprint running
Date:11/17/2009

-bodied male sprinter.

Bundle noted that most of the 15-30 percent speed advantage enjoyed by Pistorius is explained by how quickly the lightweight blades allow him to reposition his limbs: "Even in comparison to those male sprinters with the most extreme adaptations for speed in recorded human history, Oscar Pistorius has limb repositioning times that are literally off the charts. Usain Bolt is considered somewhat freakish because he outruns his opponents by 2-4 percent. At top speed, Oscar Pistorius repositions his limbs 15 percent more rapidly than six of the most recent world record holders in the 100 meter dash, including Usain Bolt."

In the aftermath of the IAAF eligibility controversy, both Weyand and Bundle agreed that the initial ban was not scientifically supported and that the May 2008 ruling of the CAS to overturn the ban was sound on the basis of the incomplete evidence considered. Pistorius' case was successfully presented by the law firm Dewey & LeBoeuf of New York.

"We are pleased to finally be able to go public with conclusions that the publishing process has required us to keep confidential until now. We recognized that the blades provide a major advantage as soon as we analyzed the critical data more than a year and a half ago," said Weyand and Bundle in a statement.

Speaking for both investigators, Weyand indicated: "We admire the unique athletic achievements of Oscar Pistorius and are grateful for his willingness to share these important results for the general benefit of athletes and athletics. We acknowledge Dr. Rodger Kram of the University of Colorado Boulder whose efforts were essential to publishing this analysis and an earlier manuscript cooperatively. We also wish to acknowledge the data and work of Dr. Peter Bruggeman and colleagues, which contributed to the comprehensiveness of these conclusions."

"Finally," Weyand said, "we also commend the recent, single-limb amputee work of our collea
