Features of Power of Theta-rhythm EEG of Athletes of Acyclic Sports During Intellectual Activity
Keywords:
electroencephalogram, power spectral density, mental activity, acyclic sportsAbstract
Electrical activity in the cerebral cortex of theta-rhythm EEG was studied in the functional state of rest and with open eyes during mental activity. In research 68 healthy, right-handed young men of 17–21 years, took part, they were divided into two groups: a group of athletes (33 persons) – young men who at 12 years of age began systematically exercise with sports with acyclic structure of movements; and a control group (35 people) – young men who do not exercise regularly. Dynamics of spectral power density shows the differences in the brain activity of young men of experimental groups. In the group of athletes, the transition from the state of rest to the mental activity was registered more local growth of spectral power density in front associative areas of the cortex of the brain in comparison with a control group.
