Introduction. Physical development of younger generation is considered to be important part of age biology issues. This research aimed to conduct the assessment study on physical development of modern children and adolescents born and permanently living in extreme conditions of the North-East of Russia, and compare it to the 2001 survey. Materials and methods. Four thousand two hundred and seven schoolchildren aged 10–17, both males and females, participated in the 2019 monitoring. Basic anthropometric parameters were measured for each student: Body Length, Body Mass, Chest Circumference in pause, and Body Mass Index was calculated. We comparatively analyzed the age dynamics of the studied anthropometric indicators and the rate of change in these indicators during the year within each age group, as well as differences between the same age groups of the 2001 and 2019 surveys. Results. Modern adolescents tend to be higher in somatometric indices as compared to those of previous years. Modern boys exhibited higher BM within the age of 13–16 (p<0.05), BL within the age of 11–16 (p<0.05), and CC at the age of 17 (p<0.05). They experience the active increase in their BM, BL, and CC starting at 12–13 while the boys from the 2001 survey demonstrated the comparable increase (p<0.05), they are higher in BM at the age of 12–15 (p<0.05), and CC at ages of 11 and 13–14 (p<0.05). Modern girls show the active increase in their BM, BL, and CC starting at 11–13, while it lasted until the age of 14 in the girls from the 2001 survey. The BMI variables proved to increase towards overweight and obesity: boys gained 2.2 kg and 5.4 kg, and girls 9.5 kg and 5 kg, respectively. Conclusion. We found the shift of the growth leaps in BL, BM, and CC to younger ages as characteristic of the modern adolescents. In general, higher variables of the studied indicators are evidence of the ongoing acceleration processes in physical development. @ 2023. This work is licensed under a CC BY 4.0 license
