Electrophysiological indices of systemic cerebral activity in the mobilization of functional reserves during muscular fatigue

Electrophysiological indices of systemic cerebral activity in the mobilization of functional reserves during muscular fatigue

The functional reserves of the systemic activity of the human cerebral cortex were studied in healthy mean, aged 18-24, during muscular fatigue. A system of interrelated activity, which included the motor projections of working muscles and premotor cortex, was formed in the cerebral cortex during muscular work. During compensated fatigue the intensified spatial synchronization of EEG, mostly potentials of prefrontal areas with other cortical zones, was observed. Transition from the optimal state to the compensated fatigue state was accompanied by a more significant increase in spatial EEG synchronization during increased motivation and when the highest level of specific working capacity in the annual training cycle was achieved, compared to usual work. The retention and intensification of interrelationship at the working frequency of potentials of the prefrontal, premotor and motor areas during the decompensated fatigue stage was only possible due to a reduced interrelationship between all other cortical zones.
