O Efeito dos exercícios de Endurance na microbiota intestinal: uma revisão sistemática

Abstract

Background: Endurance exercise is defined as that performed for a prolonged period and at moderate intensities, which can be performed in different modalities. Studies suggest that the intestinal microbiota has several functions related to the health of the host. The practice of Endurance exercises can alter the intestinal microbiota. This systematic review aims to verify the effects of endurance exercises on the intestinal microbiota. Methods: The systematic review was conducted with the aim of evaluating the results of Randomized Clinical Trials (RCTs) and Non-Randomized Clinical Trials (NECR’s) on intestinal microbial alterations in endurance exercise practitioners. Five literature databases were considered (EMBASE, MEDLINE, ISI - Web of Science, Scopus and CENTRAL). The protocol that delimits this work was registered in PROSPERO (International prospective Register of Systematic Reviews). Results: 1965 records were identified during the bibliographic search. After reviewing the titles and abstracts, 27 publications were selected for the complete reading of the texts, of which only four met the selection criteria. No study failed to demonstrate a significant difference in the bacterial phylum, with some caveats. Four studies showed only significant changes in only a few genders. The comparison of studies demonstrates the existence of alterations in the intestinal microbiota of people who practice endurance exercises. Conclusions: The results of this review suggest that endurance exercise has the potential to offer beneficial changes in the gut microbiota. Based on the evidence from this review, some samples of the selected works had alterations in the intestinal microbiota. However, some studies reported that there were no significant changes in the diversity of the gut microbiota of individuals engaged in endurance exercise. This situation suggests that further studies are needed to determine the size of the effect of endurance exercise
