Objective of the study was to study the physical development of the child population in various regions of the country after the removal of restrictive measures associated with a new coronovirus infection.
Methods and structure of the study. In 2021, as part of the all-Russian monitoring of the physical development of schoolchildren, the physical development of younger schoolchildren 8-10 years old, performed in the Moscow region (337 schoolchildren) and the Arkhangelsk region (175 schoolchildren), was studied. These regions were chosen because they have significant differences in climatic, geographical and other conditions. Archival data were used for comparison. The statistical software package Statistica 13 PL was used.
Results and conclusions. Similar trends were recorded in the regions, there is an activity of the acceleration process with disharmonious manifestations, accompanied by high rates of weight gain and skin-fat folds. Based on the data obtained, it is concluded that the secular trends identified in the regions of the Russian Federation since the end of the 20th century persist at the beginning of the 21st century and continue to be disharmonious. Today, states, society, schools and families face the challenge of ensuring and maintaining children, adolescents and youth commitment to a healthy lifestyle, and especially in terms of an optimal motor regime, organized both at home and at school.

Keywords: younger schoolchildren, monitoring of physical development, pandemic of a new coronovirus infection.
