Adaptation and regulatory systems in primary schoolchildren

Aim. The paper aims to study the effect of academic load on the dynamics of regulatory systems and adaptation in Moscow primary schoolchildren. Materials and methods. Primary schoolchildren (40 females and 41 males) ages 6-11 from the University School (Moscow) with a five-term academic year took part in this study. During the study, data on children’s weight and height and state of their regulatory systems were obtained by using the Varicard-express diagnostic device. Results. The obtained data on the activity of regulatory systems during the 1st examination showed that only 14.8 % of children had normal functioning of the regulatory system, and the number of these children decreased twice (to 7.4 %) in the fourth term. The number of schoolchildren characterized by the prenosological state increased from 64.2 % in the second term to 71.6% in the fourth term. The number of children with normal values of the stress index decreased by 11.1 % and reached 50.6 %, and the number of children characterized by compensated distress also known as the initial level of stress of regulatory systems increased 1.4 times from 19.8 % to 28.4 % in the fourth term under the influence of academic load. Conclusion. Screening and monitoring of regulatory systems reflect the level of adaptation of primary schoolchildren to academic load. They also allow to control the dynamics of children’s adaptation and to select effective didactic, psychological and pedagogical methods and tools taking into account children’s health status.
