Exercise can help modulate human gut micriobiota - Robert McFadzean - 2014
Abstract
Moderate exercise has been shown to be beneficial to health in many ways, including reducing stress, building a stronger immune system and increasing cardiovascular health. Recent studies in the human gut microbiome have demonstrated benefits of certain microorganisms in aiding human pathogen resistance and reduction of inflammation. The hypothesis is that exercise can help modulate the human gut microbiota. Here we show that increasing exercise frequency selects for a diverse community of microbes that contribute to a healthier environment. Individuals who exercised more often showed a significant elevation in their diversity, as well as a significant elevation of certain members of the Firmicutes phylum (including Faecalibacterium prausnitzii, uncharacterized species of genus Oscillospira, Lachnospira, Coprococcus, and uncharacterized families of Clostridiales).
