EEG background activity was analyzed in relation to physical exercise. An ergometer test provoked an increase of the mean alpha frequency (MAF) over the occipital and precentral cortical regions dependent on the initial load. Special wrestling exercises caused similar changes of the MAF, owing to the intensity and duration of work. We propose phasic and tonic changes of CNS activation related to information processes during motor control are responsible for the observed increase of the MAF.
