Endurance Exercises May Change the Composition of Gut Bacteria

A new Finnish study, published in the journal Frontiers in Microbiology, finds that endurance exercises may change the composition of gut microbiota.

The researendurance exercises change gut bacteriachers developed a 6-week program of bicycle training and enrolled 17 overweight women for this program. All women led a sedentary lifestyle before joining the study.

At the end of the program, the scientists noticed that the number of proteobacteria, gut bacteria that cause inflammation, decreased and the number of beneficial bacteria Akkermansia, linked to better metabolism, increased.

The corresponding author of the study Satu Pekkala, an Academy of Finland research fellow affiliated with the Faculty of Sport and Health Sciences of the University of Jyväskylä, explains: “These changes are beneficial for cardiometabolic health, because VLDL transports lipids from the liver to peripheral tissues, converts into ‘bad’ LDL [low-density lipoprotein] cholesterol in the circulation, and thus has detrimental cardiovascular effects.”
