Oscar Pistorius

In 2007 Pistorius took part in his first international able-bodied competitions. However, his artificial lower legs, while enabling him to compete, generated claims that he has an unfair advantage over able-bodied runners. The same year, the International Association of Athletics Federations (IAAF) amended its competition rules to ban the use of "any technical device that incorporates springs, wheels or any other element that provides a user with an advantage over another athlete not using such a device". It claimed that the amendment was not specifically aimed at Pistorius.
