Introduction. It is known that the discrepancy between physical activity and functional capabilities of schoolchildren leads to pre-pathological conditions [1]. This is especially important, since a number of intensifying pedagogical methods make great demands on the student's body. In our opinion, special attention should be paid to the biological component itself. When analyzing the basic program documents that regulate the essence of the Genesis of physical education in school, this component is not given enough attention.
The aim of the study is to study the accuracy of movement control in solving motor problems of primary school children in the framework of psychophysiological activities.
Methodology and organization of the study. During the study, observations were made in 311 students (149 boys and 162 girls) of a General education institution-gymnasium No. 18 and secondary school No. 63. Krasnodar at the age of 7-10 years.
For measurements, the hardware and software complex "NS-Psychotest" was used (I. N. Mantrova, 2008). Students took part in the observations on a voluntary basis, and informed consent was obtained from their parents and guardians. The research was conducted repeatedly.
The results of the study and their discussion. As shown by the research, the degree of influence of gender on the result of motor act was not revealed. As they grow older, children aged 9-10 years (13.64±1.23 s and 12.87±0.78 s, respectively) show significantly low values of the duration of touches, which indicates a high degree of sensory control over movements relative to the detected indicators in children aged 7-8 years (16.41±0.21 s and 15.82±0.42 s). It should also be noted that there is a significant degree of expression of complex motor quality-coordination in children aged 9-10 years, which is indicated by relatively small values of the number of touches (erroneous actions) (16,22+2,10; 15,31±1,12) relative to the parameters of students aged 7-8 years (35.47+1.96 and 38.29±2.43). As for the parameter of the intensity of erroneous actions (number of touches per second), even here low values were registered in schoolchildren aged 9-10 years (1.94±0.12; 1.30±0.21) in comparison with children aged 7-8 years (3,32±0,14; 2,89±0,09).
Conclusions. In children aged 7-10 years, no intra-group (age-related) differences in gender were registered, and the formation and regulation of movements in younger schoolchildren develop as the ability of Central structures to consolidate afferent and efferent signals improves.
