Do amputee sprinters using running prostheses, or blades, have a competitive advantage?
The world’s fastest 400-meter sprinter, Blake Leeper, was ruled ineligible to compete in the Tokyo Olympics due to having an assumed advantage, but
a new study with the most comprehensive set of data ever collected from elite runners with bilateral leg amputations compared performance data from Leeper, South African “blade runner” Oscar Pistorius and other bilateral amputee sprinters with those of the best non-amputee sprinters in the world across five performance metrics and found no advantage.
