Now the proverb "in healthy body – healthy mind" has a scientific explanation. Scientists from the University of Colorado have proven that regular exercise in childhood affect the intellectual abilities of the child. This relationship occurs in the most unexpected way: with the help of intestinal bacteria.
Sport activates the intestinal flora, resulting in improvement of metabolism all organizma, including the brain. The researchers watched the activity of laboratory rats. Animals are stimulated to exercise, and the results of the physical and intellectual development of the experimental mice were compared with those in the control group.
It appeared that the young and active rats had the special composition of the intestinal flora. In the intestine of this group of individuals lived more probiotic bacteria, accelerating the metabolism. Experts believe that bacteria can directly affect the level of intelligence not only rats, but all other mammals, including humans.
