Discovered unexpected consequences from physical education classes

The research of American scientists from the University of Illinois at Urbana-Champaign have shown that exercise can affect the condition of the intestinal microflora. In particular, experts linked exercise with a balance of butyric acid in the intestine, which depends on the ability of the immune system against pathogenic bacteria.


Scientists conducted an unusual experiment – they were transplanted into mice with sterile intestines fecal microbiome, which was assembled in two groups of rodents, with low and high levels of physical activity. As a result of such transplant in animals that received the bacterial material from the active mice, significantly improved intestinal health.

In addition, the experiment was conducted with the participation of women with normal and overweight. 6 weeks participating in regular sport (cardio) then for the same time period they didn’t have to train at all. It turned out that, because of the physical exercises in the intestinal microflora of subjects has been an overall change in their intestines increased the level of butyric acid. In women with normal weight increase was significant in women with excess weight is less serious.

Scientists have noted that the butyric acid produced in intestine, promotes effective digestion, protects against spread of pathogens. When women stopped exercise, the production of butyric acid in the gut again subsided.

The results of the two projects, scientists noted that physical exercises are beneficial to the microflora of the intestine regardless of dietary preferences.
