After the enhanced games: rethinking the governance of human enhancement in sport

The inaugural Enhanced Games have transformed a largely hypothetical debate about enhancement-permissive sport into an observable governance experiment. This Perspective asks what that experiment reveals about the governance of human enhancement in sport. Our central argument is that permitting enhancement does not abolish the regulatory boundary; it relocates it. Once selected enhancement practices are permitted, decisions remain necessary about acceptable interventions, conditions of use, medical eligibility, monitoring, verification, enforcement and dispute resolution. These decisions must account for the heterogeneity of both performance benefits and health risks. We use a regulatory-gap perspective to examine the continuing requirements of assessment, analytical verification, implementation and adjudication under this relocated boundary. The incorporation of the ASCEND001 study shows how these requirements extend to the overlapping roles of athlete, competitor, patient and research participant. Viewed together, these roles suggest that the Enhanced Games should not yet be understood simply as a replacement for conventional competitive sport, but as a hybrid experiment combining competition, biomedical enhancement, medical supervision, research, longitudinal data generation and commercial activity. The relevant comparison is therefore not regulation versus freedom, but between regulatory architectures and the ways in which each distributes risk, autonomy, responsibility and institutional control.
