Abstract: Running-specific leg prostheses (RSPs) are comprised of carbon-fiber, designed to emulate the spring-like function of tendons during level-ground steady-speed running, and allow considerable elastic energy return; however, unlike biological legs, passive-elastic RSPs cannot generate mechanical power anew, vary stiffness, nor allow foot-ground clearance during the swing phase. The international association of athletics federations has banned the use of RSPs in non-amputee track and field competitions. Thus, understanding how use of RSPs affects performance is paramount to decisions of inclusion or exclusion in sport. I will present a series of studies that assess the biomechanical and metabolic effects of using RSPs during running, sprinting and jumping to determine if use of such prostheses augment or impair performance for athletes with leg amputations.
