Exercise can improve your gut's bacteria
Exercise may change the composition and activity of the trillions of microbes in our guts in ways that could improve our health and metabolisms over time, a new study has found.
The results provide novel insights into how exercise can affect even those portions of our bodies that seem uninvolved in workouts, perhaps providing another nudge to stick with our exercise resolutions this year.
In broad terms, our microbiomes tend to be relatively stable, most studies show. But our microbiomes can change as our lifestyles do. Diet clearly affects the makeup of a person's microbiome, as do illness, certain drugs, how much we weigh and other factors. Exercise also has been associated with variations in the microbiome. Past studies have shown that endurance athletes tend to have a somewhat different collection of microbes within their intestines than sedentary people do, especially if the athletes are lean and the sedentary people are not.
