Aspects of Gut Microbiome Composition Correlate with Physical Activity in Older People (opens in new tab)

Exercise influences the composition of the gut microbiome, which in turn influences capacity for exercise. Thus we see correlations in older people between the composition of the gut microbiome and observed level of physical activity and fitness, but breaking that down into specific contributing mechanisms and their relative importance is a challenge. The fastest path to answers is to alter the gut microbiome composition in defined ways and see how it affects capacity for physical activity. A...
