Genetic Enhancement in Sport: Just Another Form of Doping?

Patented genetic technologies such as the ACTN3 genetic test are adding a new dimension to the types of performance enhancement available to elite athletes. Organized sports organizations and governments are seeking to prevent athletes' use of biomedical enhancements. This paper discusses how these interdiction efforts will affect the use and availability of genetic technologies that can enhance athletic performance. The paper provides a working definition of enhancement, and in light of that definition and the concerns of the sports community, reviews genetic enhancement as a result of varied technologies, including, genetic testing to identify innate athletic ability, performance-enhancing drugs developed with genetic science and technology, pharmacogenetics, enhancement through reproductive technologies, somatic gene transfer, and germ line gene transfer.
