Genetically-enhanced jocks

Science News has an interesting feature about gene doping, a form of gene therapy that could improve an athlete's strength. Apparently, as gene therapy technology continues to improve, gene doping could become a problem by the 2008 summer Olympics.

"Gene doping could someday provide extra copies of genes that offer a competitive advantage, such as those that increase muscle mass, blood production, or endurance. The products of gene doping would be proteins similar, if not identical, to the body's versions and would therefore be less detectable in an athlete than are performance-enhancing drugs such as steroids and insulin. Consequently, rules against gene doping might be difficult to enforce."
