Figures & data
Table 1. Correlations between exercise intensity (creatine kinase), diet (protein intake) and diversity (estimated over 5 metrics; chao1, Simpson, Shannon, phylogenetic diversity and observed species). Table displays Pearson correlation coefficients followed by p-value in all incidences. P >0.05 was taken to be significant
Figure 1. Schematic overview of potential sites of interaction between the biological adaptations to exercise and the microbiota. This is intended to be representative not comprehensive. Exercise is linked with a diversity of biological responses including a modifying influence on the brain-gut-microbe axis, diet-microbe-host metabolic interactions, neuro-endocrine and neuro-immune interactions. For example, exercise is long known to increase vagal tone - the hard wiring of the gut - which is anti-inflammatory and immune-modulatory. The latter might represent an indirect means by which exercise conditions gut microbiota composition.
