According to a new research from Binghamton University, State University of New York, exercise can do more than controlling weigh gain and boosting heart function. It might make gut microbiome healthier. Researchers recruited men and women from the SF State campus, and tested their cardiovascular fitness on a treadmill. They also assessed their body composition on displacement chamber that determines a person’s fat and fat-free mass.
Participants kept food logs for seven days and provided stool samples at the end of the week, researchers extracted DNA to analyze the bacteria composition in the samples to investigate the ratio of bacteria- firmicutes to another group, bacteroides, which can be used to gauge overall gut health and composition.
Analysis showed that participants with the best cardiovascular fitness had a higher firmicutes to bacteroides ratio. While most gut bacteria can be beneficial (even bacteroides in some cases), firmicutes bacteria are associated with metabolic byproducts that prevent bacteria in the gut from leaking into the body. These metabolic byproducts strengthen the intestinal lining and prevent leaky gut syndrome, exercise is crucial for increasing beneficial bacteria in the gut and increase longevity.
