Healthier Hearts Equal Healthier Guts

This article covers research presented by ACSM Southwest Chapter member Ryan Durk at the 2018 ACSM Annual Meeting in Minneapolis.

It turns out that exercise can do more than slim down your waistline and boost heart health. It might also make what's inside your gut healthier, according to a new study by San Francisco State University.

In this first-of-its-kind study, just published in the International Journal of Sport Nutrition and Exercise Metabolism, recent SF State graduate student Ryan Durk and Assistant Professor of Kinesiology Jimmy Bagley partnered with the SF State Health Equity Research (HER) Lab to test the relationship between gut health and cardiovascular fitness.

Durk (who received his master's degree in kinesiology last December) recruited 20 men and 17 women, mostly from the SF State campus, and tested their cardiovascular fitness on a treadmill. He also assessed their body composition in the lab's BOD POD, an air 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. The HER Lab then extracted DNA to analyze the bacteria composition in the samples. The researchers were investigating the ratio of bacteria called firmicutes to another group, bacteroides, which can be used to gauge overall gut health and composition. more
