The study of the general functional state of the brain of 175 students of the first courses of the physical education faculty was realized by the data of a simple visual-motor reaction by T.D. Loskutova’s method in the state of the relative muscular rest and at the fifth minute of restoration after the physical veloergometric activity by the closed cycle (D.N. Davidenko’s method). The studied parameters of the general functional state of the brain of the studied contingent (system functional level, reaction stability, functional possibilities level), despite an age and research conditions, can be divided in three main groups – with the low, middle and high level of the central nervous system. Differences are observed only in the percent ratio of studied persons in groups.
There were established two main types of reaction of the general functional state of youngsters’ brain that are characterized by the different directionality, changes depth, quantitative ratio and their dependence on the initial state. The high level of the general functional state of the central nervous system conditions the decrease, and the low one, on the contrary, provides the increase of its criteria under the influence of external factors. The reaction of students’ central nervous system must be evaluated by the diapason of shifts from the initial level, according to the “pendulum” law: changes in the diapason ±25 % must be considered as an activation reaction; ±50 % – as a strain reaction and fluctuations more than ±50 % – as a pre-pathology with a possible transfer to the disease state
