Metabolomics incorporates the study of metabolites that are produced and released
through physiological processes at both the systemic and cellular level. Biological compounds
at the metabolite level are of paramount interest in the sport and exercise sciences, although
research in this field has rarely been referred to with the global ‘omics terminology. Commonly
studied metabolites in exercise science are notably within cellular pathways for ATP
production such as glycolysis (e.g. pyruvate and lactate), β-oxidation of free fatty acids (e.g.
palmitate) and ketone bodies (e.g. β-hydroxybutyrate). Non-targeted metabolomic
technologies are able to simultaneously analyse the large numbers of metabolites present in
human biological samples such as plasma, urine and saliva. These analytical technologies
predominately employ nuclear magnetic resonance spectroscopy and chromatography coupled
to mass spectrometry. Performing experiments based on non-targeted methods allows for
systemic metabolite changes to be analysed and compared to a particular physiological state
(e.g. pre/post-exercise) and provides an opportunity to prospect for metabolite signatures that
offer beneficial information for translation into an exercise science context, for both elite
performance and public health monitoring. This narrative review provides an introduction to
non-targeted metabolomic technologies and discusses current and potential applications in
sport and exercise science.
