Physical enhancement of human performance: is law keeping pace with science?

In the area of genometry-the nascent field of science and technology that proposes to apply enhanced understanding of the human genetic code to reshaping our individual and collective destinies-no topic has generated more interest among the general public, as well as in the athletic community, than the potential for physical enhancement of the human body and its performance. Genometric experiments have produced physically enhanced mice, and the production of similarly enhanced humans may not be far off. Although it is not the objective of most genometric research, the day will come when gene-based "treatments" will enable individuals to build muscle or increase endurance faster than is possible through conventional methods. This article describes developments in the area of physical enhancement that may find application in the "gene doping" of athletes. For example, human performance-related genes may be delivered to athletes using tools developed for research in gene therapy; the protein products of these genes may be administered in recombinant form; and recently discovered small-molecule activators of the major genetic regulatory pathways of physical prowess may be taken orally, providing "exercise in a pill". This article also describes US and international attempts to regulate and punish the use of prohibited techniques for performance enhancement among athletes. As science advances, defining and detecting "gene doping" becomes increasingly complex. Thus, the study of physical enhancement provides an ideal starting point for the interdisciplinary Redefined Destinies Colloquium's examination of the intersection between law and science.
