Psychophysiological indicators of 7-10 year-old children at the beginning of the academic year of the educational institution

The analysis of sample programs as part of physical education in schools revealed that they have practically no application tasks of elements of physical education in connection with the development of cognitive, emotional-volitional and other areas, psychophysiological components of the formation of the body of schoolchildren and others are not taken into account. 7-10 year-old children showed a tendency in optimization of a functional organization of a number of voluntary activities, including sensorimotor functions. The research aim was to study some psychophysiological indicators of primary school children. The observation was conducted at the educational institution of gymnasium № 18, secondary school № 63, laboratory of the Anatomy and Sports Medicine Department of the Kuban State University of Physical Education, Sports and Tourism. 311 schoolchildren (149 boys and 162 girls) of 7-10 years old took part in the study. Hardware and soft-ware computer complex «NS-PsychoTest» was used in the study. A simple visual motor reaction was studied among the observed, reaction to a moving object, «discrimination reaction», «reaction of choice», «assessment of attention», «interference immunity».The obtained indicators in a simple motor reaction could be due to the anatomical features of the analyzer, properties of nervous processes, psychophysiological state of the body and motor-coordination potential of the subject. From which it follows that the period of the sensorimotor reaction decreases with age, the explanation for this phenomenon is the process of maturation of the central structures of the brain and improvement of the functional state of the neuromuscular system. The indicators of a complex sensorimotor reaction to a moving object demonstrated that the balance degree of processes of excitation and inhibition by strength is higher among 9-10 year-old children, this indicates the balance of nervous processes and stability of the nervous system at this age.The revealed indicators in «discernment reactions» and «selection reactions» show mobility of nervous processes. With age, children significantly decrease the number of delayed and anticipatory reactions, due to the intensive development of central mechanisms.
