  • 9. Controversy
    On January 14, South African sprinter Oscar Pistorius was banned from the 2008 Olympics by the IAAF(The International Association of Athletics Federations). Tests by Dr. Briggemann, a leading expert in biomechanics of running, showed that Pistorius’ prosthetics gave him an advantage over runners with human legs. His legs allow him to loose less energy with a larger energy return and less fatigue.
  • 10. Controversy Continued
    When running, the human foot touches the ground and goes through a pause and then a push off phase. Energy is lost in this process. The tests by Briggeman showed that the Cheetahs lost 30 percent less energy than an average human would without a prosthetic would. Also, the Cheetahs would allow a sprinter to use 25 percent less oxygen than a sprinter without the prosthetics.
