Elite athletes exhibit higher gut microbial diversity and a specific enrichment of bacteria involved in short-chain fatty acid (SCFA) production compared to sedentary controls.
Elite athletes tend to have gut microbiomes enriched in bacteria that produce beneficial short-chain fatty acids (SCFAs) like butyrate. This is linked to their high training volume and specific metabolic demands, suggesting that consistent endurance training may shape the microbiome toward more efficient energy metabolism.
Elite athletes seem to have a higher gut microbial diversity, shifted toward bacterial species involved in amino acid biosynthesis and carbohydrate/fiber metabolism, consequently producing key metabolites such as short-chain fatty acids.
Why this rating
Supported by multiple studies on elite rugby players, cyclists, and race walkers (refs 48, 61, 62, 63, 64).
