Короткий опис (реферат):
The health of student youth is largely determined by the level of functional capabilities
of the organism, which depends on the level of motor activity, that is the total number of
movements that a person performs in a given period of time. The purpose of the work is
to establish the features of the relationship between the characteristics of adaptive
capacity, functional status and level of development of psychophysiological functions
and criteria for motor activity of students. The research was conducted on the basis of
National Pirogov Memorial Medical University, where 385 students (200 young girls and
185 young boys) were supervised, who, taking into account the peculiarities of the
distribution of different levels of motor activity, were divided into 3 comparison groups
- with potentially low, medium and potentially high levels of motor activity. The values of
daily energy consumption, number of locomotions and duration of the dynamic
component in the daily budget were used as the leading criteria of hygienic assessment
of students' motor activity. Functional features and adaptive capabilities of the organism
were determined using conventional methods. The analysis of the obtained results
involved the use of a standard application package of multidimensional statistical
analysis "Statistica 6.1 for Windows". The results of studies conducted on the basis of
correlation analysis procedures indicate the fact that the largest number of correlations
between the characteristics of psychophysiological functions and the leading
characteristics of health and indicators of academic performance in professionally
oriented disciplines studied are recorded in girls, and boys who belonged to the group
with an average level of physical activity (daily energy expenditure of 9000-11000 kJ in
young girls and 11000-13500 kJ in young boys). The use of cluster analysis procedures
during the prognostic assessment of indicators of health and academic performance in
professionally-oriented disciplines, made it possible to identify 3 clusters of the studied
characteristics of the functional state of students, which have the most pronounced
effect on their values: visual-motor speed cluster (indicators of the latent period of
simple and differentiated visual-motor response), visual-sensory cluster (indicators of
critical fusion of light flickers and efficiency of work performed) and integrative-coordination cluster (a number of indicators that reflect the properties of major nervous
processes, characteristics coordination of movements, indicators of attention functions,
etc.). Using factor analysis procedures, it determined that both young girls and young
boys have the most positive impact on academic performance in vocational disciplines
such factors as "functional state of the visual sensory system", "functional state of
coordination" and "functional state of higher nervous activity".
