Early Life Exercise, Gut Microbes

Science Daily: Early-life exercise alters gut microbes, promotes healthy brain and metabolism

summary - The human gut harbors a teeming menagerie of over 100 trillion microorganisms, and researchers have discovered that exercising early in life can alter that microbial community for the better, promoting healthier brain and metabolic activity over the course of a lifetime.

While this diverse microbial community remains somewhat malleable throughout adult life and can be influenced by environmental factors such as diet and sleep patterns, the researchers found that gut microorganisms are especially 'plastic' at a young age.
