Abstract
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
Highlights
Adaptation mechanisms attract attention of many researchers, because the main factor that determines the success of the activity and human health status is the effectiveness of adaptive processes [1, 2]
The determination of the general functional state (GFS) of the brain was realized by reflexometry, by data of a simple visual-motor reaction registration, by T.D
Results of research and their discussion According to initial values of reaction stability (RS), system functional level (SFL), FPR, examined persons may be divided in three main groups, despite their age and research conditions [10] – with the low, middle and high functional level of the central nervous system
Summary
Adaptation mechanisms attract attention of many researchers, because the main factor that determines the success of the activity and human health status is the effectiveness of adaptive processes [1, 2]. Adaptation to the study at higher school takes place under the influence of the complex of specific factors that cause the essential strain of regulatory systems of the organism and is a multi-level process, accompanied by socio-psychophysiological and physiological reactions [3, 4]. Under these conditions is registered the unequal degree of the strain of regulatory systems of the organism at different study stages, connected with “critical periods” of students’ life. These periods are divided in the primary (first and second years) and final (pre- and graduate years) ones [4, 5]
