Professional athletes have different guts than you, study shows

An athlete’s microbiome is primed for tissue repair and to harness energy from the diet

Scientists have indicated that the micro organisms that reside in the gut, or gut microbiome, of professional athletes are distinct from those of the general public both functionally and metabolically.

Scientists at the Science Foundation Ireland-funded APC Microbiome Institute and Teagasc, together with collaborators at Imperial College London, have published their research on the microbiome of professional rugby players in the prestigious scientific journal, Gut.

In particular, the scientists found that the athlete’s microbiome is primed for tissue repair and to harness energy from the diet, reflecting the significant energy demands and high cell-turnover evident in elite sport. Thus, the state of physical fitness is not limited to the athlete alone; it appears to also include conditioning of the microbiota.

The team had previously found that the gut microbes of professional rugby players differ considerably from that of healthy controls. The research, which involved 40 rugby players on the Irish squad, suggested links between diet and exercise and the diversity of microbes in the gut.

“Our earlier work, also published in Gut, had shown that the microbiome of the athletes differed in composition from that of non-athletes but now we have found that the functional behaviour of the microbiome separates the athletes and controls to an even greater degree,” said Professor Fergus Shanahan, director of the APC Microbiome Institute in Cork.

“Elaboration and further exploration of the components of this exercise and diet-microbiome paradigm may inform the design of exercise and fitness programmes, including the area of tailored nutrition for both athletes and non-athletes,” noted Dr Orla O’Sullivan, senior author on the publication.
