Functional status of the central nervous system in girls aged 16-18 years old

Abstract

Background. The objective of the study was to explore the dynamics of the functional state of the central nervous system (CNS) and neurophysiological processes of girls 16-18 years old in the context of their transition to a new level of social organization. . Material and methods. The functional state of the CNS was studied in girls 16-18 years old in a state of relative muscular rest through observation of visible motive reactions, Loskutova’s method, and in the fifth minute of renewal after the physical loading with variable power. Results. W e f ound t hat 1 7 y ear-old g irls h ad t he b est f unctional C NS c apabilities. T he reduced adaptive capacity of the CNS in 16 year-old girls is due to their necessity for adaptive reorganization of regulatory mechanisms to new social conditions: examinations and university entry. After physical activity, 16 and 18 year-old girls registered stress reactions, indicating decreased CNS adaptation. Conclusions. 17 year-old girls were observed at rest to have better CNS functionality compared to the other age groups. Analysis of the dynamics of the functional CNS states of 16–18 year-old girls after exercise resulted in the identification of two main reaction types: 1) reduction of the basic criteria at high initial values; 2) increase of criteria of a general functional state of a brain at low raw data.
