In the last decade, the problem of preserving, maintaining and developing mental performance in children has become increasingly important due to the intensification of the educational process, the introduction of new forms of education that negatively affect the health indicators and neuropsychic development of children. Purpose: to study the initial state of mental performance of schoolchildren in Almaty. Materials and methods: In this regard, the initial state of mental performance of 2134 schoolchildren aged 6-17 in Almaty was studied. The mental performance of schoolchildren was determined at the beginning of the school year by conducting a correction test according to the Anfimov table (4-minute dosed task). Quantitative and qualitative indicators of mental performance were determined. The daily and weekly dynamics of mental performance was analyzed. Results and discussion. The data of the correction test at the beginning of the academic year testified to a satisfactory Academic Editor: Arzikulov A. Professor, Andijan State Medical mental performance. The mental performance of schoolchildren in the study region was Institute characterized by a clear dependence on age (p<0.05). With the increase in the age of schoolchildren, a uniform increase was observed. Schoolchildren of elementary grades Received: 10 October 2022 were characterized by lower coefficients, which is physiological. Quantitative (volume of Accepted: 17 October 2022 Published: 25 October 2022 work S, Q, M, SPI speed, N) and qualitative (number of errors n, accuracy of task fulfillment А, UVN, Р) indicators corresponded to its 1st phase.

Охрана здоровья детского населения являет- ся одним из важнейших и необходимых условий физического и психического развития детей [1,2,3]. Выраженный рост распро- страненности морфофункциональных отклонений, хронических соматических заболеваний среди школьников в настоящее вре- мя вызывает особую тревогу[3,4]. Одной из возможных причин возникновения и развития высокой заболеваемости является умственное переутомление школьников, когда происходит несо- ответствие функциональных возможностей организма и объема www.ijsp.uz 34 2022 / Issue 06 / Article 06 International Journal of Scientific Pediatrics published: 25 October 2022 и сложности учебной нагрузки [5,6,7,8,9]. Как свидетельствуют литературные источники, степень умственной и физической на- грузок во время учебного года в современных условиях нуждается в изучении и в управлении для проведения их квалифицирован- ного планирования и распределения с учетом возрастно-половых и морфофункциональных возможностей школьников [2,3,10, 11, 12]. Современные модели обучения основаны на интенсифика- ции учебного процесса при резком ограничении занятий физи- ческой культурой. Такие системы образования не обеспечивают целостного интегративного воздействия на здоровье школьни- ка с целью гармоничного развития, но создают дисбаланс меж- ду функциональными возможностями и умственной нагрузкой [5,6,7,8]. Наступление утомления и его прогрессирование относится к патологическим состояниям и ведет не только к снижению каче- ства усвоения информации, но и к нервно-психической дезадап- тации [5,6,8,10]. По
