In this article, we tackle the epistemological and ethical issues related to the use of race concepts in the genomics of sport performance and sport-related concussion (SRC). In the first part of the article, we show how the concept of race is ubiquitous in scientific literature, besides the fact that ‘race’ as other analogous population descriptors like ‘ancestry’ and ‘continent’ carry ancestral genetic heterogeneity and therefore they cannot be used to infer any kind of genetic or physiological property. Then, we (...) investigate the question of whether genomics research focusing on racial categories and race-specific genes of sport performance and of risk of health outcomes due to repetitive head impacts (RHI) is justified from an epistemological point of view, arguing that it is not; we show that the evidence supporting the existence of genetic variants determining an elite athlete status or a predisposition to health outcomes after SRC is scarce, and the use of racial categories (e.g. African or Black, Caucasian or White, Asian, etc.) as proxies for genetic variants associated with an elite athlete status/a predisposition to health outcomes after SRC is ill-conceived. In the second part of the article, we analyze the main ethical issues concerning the reification of race concepts in sport genomics, also considering the more general issue of the ethical and social impact of the use of a genetic framework in the explanation of individual differences in sport performance and SRC.
