Research is shedding new light on the connections between the gut microbiome, gut bacteria and exercise.
For example, recent studies show that an individual’s gut microbiome can change, depending on how much exercise they get and there is a correlation between cardiorespiratory fitness and increased microbial diversity in healthy humans. Also, elite athletes demonstrate unique beneficial and diverse microbiome characteristics.
Explore the research articles listed below to learn more about these insights and uncover further links between the gut microbiome and exercise.
