[Age-specific features of the movement control system in young schoolchildren]

Analyzing spatial, temporary, and strength characteristics of movements in 7-10-year-old children by using a graphoanalytical method during the reverse exercise test has indicated that overstrain occurs in all units of the structures that ensure formation and implementation of a transitional process. There are increases in regulation errors by 33%, regulation time by 21.5%, system variability by 16%, regulation stability by 19%. The variability of the system is beyond three fluctuations, which is an indicator of full transition of the movement control system in unreliability and instability. The investigations have demonstrated that the reverse exercise procedure is adequate to age-related features of children and may be useful in studying different functional systems. The graphoanalytical method of quantitative assessment of the functional status of the locomotor apparatus is of rather informative value and can be used in the professional activities of a teacher and trainer for personal assessment of the movement control system in children of different age.
