Abstract: The prosthetic legs that transtibial amputees wore in sprinting underwent a history from customary prostheses, sport prostheses to sprint prostheses.Today, sprint prostheses are all made of carbon fibre and are increasing transtibial amputees' performance in sprinting.In this article, mechanical properties of carbon fibre prostheses, evolution of sprinting prosthesis and development of transtibial amputee sprinting events are discussed, and we forecast the performance in transtibial amputees' sprinting in the future.This will exemplify the key influence of technology advancement on the development of disabled sports.
