Age-related and regional peculiarities of somatometric characteristics of young men and men of the 2nd mature age living in the conditions of the North-East and North-West of the Russian Federation

Introduction. Anthropometric characteristics are necessary to obtain objective data on human physical development that allow us to assess the age, gender and geographical features of the human body structure while geographical differences in the shape of the human body (body size, body proportions, shape and size of limbs, as well as the relative proportions between these components) are often interpreted as the result of adaptation to the climate.

Objective. Assessment of the age dynamics of somatometric characteristics of males living in various climatogeographic regions – North-East, North-West of Russia.

Materials and methods. The main anthropometric characteristics, their calculated indices, and body composition were evaluated in 333 males living in various northern regions of the Russian Federation: Magadan Region (Northeast of Russia) – 199 young men and 110 men, Murmansk Region (Northwest of Russia) – 72 young men and 32 men.

 Results: In the course of the work, a distinct regional feature has been established in the formation of the morphotype of the inhabitants of the North-East of Russia in the adolescent and mature periods of ontogenesis, manifested by large body lengths andbodydisproportionalityduetothegreatercontribution of leg length tobodylength compared to the inhabitants of the North-West of Russia. The age-related dynamics of changes in the analyzed parameters in residents of the North-East and North-West of Russia had similar trends, manifested in an increase in hypersthenization of body build, conditioned by excessive body weight.

Conclusion. The results obtained emphasize the importance of conducting continuous monitoring studies of key indicators of physical development as valuable markers for identifying geographical variations in morphological types under the influence of socio-economic and environmental factors in the northern and Arctic regions.
