According to the study, certain regions of the brain are bigger in physically active people than in less active people.Exercise keeps both the body and the mind healthy, but little is known about how and where physical exercise impacts our brains.
The size of the brain regions, however, does not increase linearly with physical activity. Comparing study participants who were sedentary and those who were just moderately physically active, the research team discovered the biggest, nearly sudden volume increase. This was especially noticeable in elderly people over the age of 70.
Young and somewhat athletic subjects who usually engaged in moderate to intense physical activity also had relatively high brain volumes. However, in even more active subjects, these brain regions were slightly larger. Also here it showed: the more active, the greater the effect, although at high levels of physical activity, the beneficial effects tended to level off.
