奥斯卡·皮斯托瑞斯是南非残奥会短跑名将，他还因参加奥运会而名声大噪。还因其假肢而得名“刀锋战士”。他还被誉为“史上跑得最快的无腿人”。皮斯托瑞斯双腿截肢，他是残奥会100米、200米和400米世界纪录保持者，残奥会奖牌获得者。

Pistorius was born in 1986 with the fibula bone missing in both of his legs. When he was 11 months old, doctors amputated his legs halfway between his knees and ankles. His disability did not stop him from enjoying sports. At school he was very keen on rugby, water polo and tennis. He started running in 2004 and says he has "never looked back".

1986年，皮斯托瑞斯生无腓骨。11个月大时，医生对其脚踝部分进行截肢。虽身体残疾，但他对体育的热情并没有减弱。在学校，他酷爱橄榄球、水球以及网球。2004年，他开始接触跑步，并称他永远不会放弃。

He runs on a pair of specially-developed carbon-fibre blades. At the 2004 Summer Paralympics, he won the 200-metre final with a world record time. In 2005, he finished first in the able-bodied South African Championships over 400 metres and won the 400-metre gold at the Paralympic World Cup. He decided to compete at the Beijing Olympics.

他的双腿装上了碳纤维假肢。在2004年夏季残奥会，他打破200米纪录，并获得金牌。2005年，皮斯托瑞斯参加南非健全田径锦标赛，并获得400米冠军，并在残疾人田径世界杯上获得400米冠军。他决定参加北京奥运会。

Pistorius tried to prove he could compete with the best able-bodied runners in the world. His biggest obstacle was the international athletics federation who decided his blades were a “technological aid” and therefore illegal. He now has his sights set on the 2012 London Olympics. His motto is: "You're not disabled by the disabilities you have, you are able by the abilities you have."

皮斯托瑞斯正在向人们证明，他能与健全运动员一较高下。国际田联认定“刀锋”有助提高比赛成绩，禁止参赛。如今，他的目标是参加2012年伦敦奥运会。他的座右铭是：“身体残疾不能证明你无能，你可以通过自己的才能证明自己的实力。”
