MENTAL WORKING CAPACITY AND IMPROVING ITS EFFICIENCY BY MEANS OF PHYSICAL CULTURE AND SPORT

Abstract

Mental performance is one of the main criteria for adapting to an academic load and an indicator of body resistance to fatigue. The mental activity of a student who is in the process of learning is a functional system with a useful end result in the form of learning success. To assess the mental work requires a systematic approach, which should include a hygienic, physiological, psycho-physiological, didactic assessment. Adaptation of children to school depends on many factors. The overall health of children has a significant impact. It was noted that a sustained mental load has a depressing effect on the body, which is expressed in a drop of qualitative and quantitative performance indicators, a decrease in the lability of the visual analyzer, deterioration of concentration, switching, attention span, short-term and long-term memory, perception. This can be expressed by a large number of errors, an increase in the latent period of simple and especially complex sensorimotor reactions. And also, it was shown that mental performance has a phase character and changes during the day, week, and year. These changes occur in indicators of higher nervous activity, deterioration of the function of the visual and auditory analyzers, a decrease in the level of blood oxygen saturation, deterioration in hemodynamic parameters, an increase in abstraction from work, a decrease in mental performance and other physiological parameters.
