The influence of physical activity status on the theta rhythm distribution

The aim of this research is to analyze the theta rhythm distribution in volunteers with a different physical activity status. We examine forty healthy males divided into four groups according to degree with physical activity (low, moderate, high dynamic and high static). The electroencephalographic data are recorded during both eyes-closed and eyes-open resting conditions. Resting state recordings had no differences in terms of the amplitude of the theta rhythm in representatives of groups. In their turn, the changes during eyes-closed and eyes-open conditions are more pronounced in the groups with high physical activity. For example, theta activity in high dynamic group decreases in the temporal region during eyes-open and increases in eyes-closed conditions. This rhythm in high static group increases in the occipital region during eyes-open and reduces in eyes-closed conditions. We assume that a physical activity status influences the formation of theta waves.
