One of the kinds of human enhancement that has received extensive philosophical attention in recent years is the use of biomedical interventions to improve the physical performance of athletes in the context of sports (Miah 2004; Murray 2009; Tolleneer 2013). One reason athletic performance enhancement garners so much attention is because of its currency, given the epidemic of “doping” scandals in contemporary sport. Another reason, however, is that it seems to serve as a paradigm case for teasing out important dimensions of the problem: it involves measurable improvements in biological capacities in a social context that is both well outside health care and defined by clear rules of engagement.
