  1. Oscar Pistorius competing in the Olympics Shannon Calahan

  2. Oscar Pistorius • Double leg amputee • Competed in 400 meter sprint in 2012 • Did not win, but controversy continues

  3. Why Mediate • Issue needs to be resolved for the future • Provides role model for other amputees • Provides equality

  4. Flex-Foot Cheetah

  5. Ban competitors because: Flex-Foot Cheetah prosthesis • Blades act as springs storing energy • No calf muscles to tire out • “…the carbon fiber blades return around 80 to 90% of the energy they store under compression”(Tucker and Dugas) • In comparison, for human legs, “…energy return ranges between 30% and 70%”(Tucker and Dugas)

  6. Ban competitors because: • Prosthesis is lighter than human leg “Pistorius’s rivals are swinging a lower leg that weighs about 5.7 kilograms, where as his lower leg only weighs 2.4 kilograms”(Eveleth, 1) • Can swing legs faster • Feet are on the ground longer • More time and force on ground results in more force pushing forward

  7. Allow Competitors because: • “The reduced weight of his legs does reduce the amount of energy he needs,butsprings do not create energy, they only store it”(Case) • According to researcher 600 meters minimum distance needed for benefit

  8. Slower start time because: • Must start in an upright position • Advantage of staying low, “It is easier to overcome inertia and create momentum, which is the key to good acceleration and to a greater top end speed”(Lee)

  9. How can we mediate the controversy? • Allow Flex-foot cheetah in specific events if research shows there is no competitive advantage • Include an asterisk next to their name and record • Asterisk is already used and accepted in sports for records in question

  10. How can we mediate the controversy? • Additional research for sprints longer than 400 meters • Additional research would be required for other sporting events and arm amputees
