An Unfair Advantage
In 2012 Oscar Pistorius, a double leg amputee from South Africa, became the first athlete to compete in both the Olympics and Paralympics in the same year. a U.S. Olympic hopeful Blake Leeper, also a double leg amputee, will attempt to make both 2016 Olympic games as well. b
Both men use Flex-Foot Cheetah blades that are custom built from high performance carbon fiber. Several studies have addressed if there is an advantage to using manufactured limbs to race. However, the results have been inconclusive. One study stated that the amputee using the blades was "physiologically similar but mechanically dissimilar" to someone running with intact legs. He uses oxygen the same way natural-legged sprinters do, but he moves his body differently. Some of the other arguments that have not been thoroughly tested include that Pistorius's and Leeper's lower legs are half the weight of an intact leg and will swing faster resulting in faster times; the blades will not tire like a lower leg will; and that more force is needed to make the blades propel the runner forward than an actual leg needs, which results in slower times.
Aside from the research cited in the case, what do you think the pros and cons are of allowing Leeper to participate in the 2016 Olympic games if he qualifies
