Can microbes increase exercise performance in athletes?

Article metrics

Faecal microbiota transplantation (FMT) has been suggested to be a therapeutic strategy for inflammatory diseases and it is known that regular physical activity can alter the composition of the gut microbiota. Now, a study proposes that FMT might increase exercise performance in athletes, raising the possibility of ‘faecal doping’.
