(1) Background: The gut microbiota might play a part in affecting athletic performance and
is of considerable importance to athletes. The aim of this study was to search the recent knowledge
of the protagonist played by high-intensity and high-duration aerobic exercise on gut microbiota
composition in athletes and how these effects could provide disadvantages in sports performance.
(2) Methods: This systematic review follows the PRISMA guidelines. An exhaustive bibliographic
search in Web of Science, PubMed, and Scopus was conducted considering the articles published
in the last 5 years. The selected articles were categorized according to the type of study. The risk of
bias was assessed using the Joanna Briggs Institute’s Critical Appraisal Tool for Systematic Reviews.
(3) Results: Thirteen studies had negative effects of aerobic exercise on intestinal microbiota such as
an upsurge in I-FABP, intestinal distress, and changes in the gut microbiota, such as an increase in
Prevotella, intestinal permeability and zonulin. In contrast, seven studies observed positive effects of
endurance exercise, including an increase in the level of bacteria such as increased microbial diversity
and increased intestinal metabolites. (4) Conclusions: A large part of the studies found reported
adverse effects on the intestinal microbiota when performing endurance exercises. In studies carried
out on athletes, more negative effects on the microbiota were found than in those carried out on
non-athletic subjects.
