A variety of negative social-economic factors as well as extreme ecological environment are pronounced in Siberia and Polar North. Therefore, research studies to determine anthropometric, psychological, and functional peculiarities of human development in this region are very important.

To evaluate the effect of genetic, ecological and social-economic life conditions in people of different ethnic origin will be possible.

The aim of this study was to compare morphological, physiological, and psychological development of different age children and adults of Tiva and Russian nationalities. The basic parameters of physical development, cardiovascular, respiratory systems, and psychophysiological state of 8-11-old children (N=1916) and 18-23-old students (N=1117) of Tiva and Russian nationalities were examined. All respondents were grouped by gender, age, and nationality.

It has been found that all parameters of physical development in 8-11-old children of both genders and nationalities increased for the last 35 years, although the level of acceleration was lower during the last 10 years. The physical development of Russian schoolchildren was higher than Tiva’s one. The number of Tiva’s children with right and ambidextrous type of functional brain asymmetry was significantly higher than in Russian group. The higher level of heart rate and blood pressure was measured in Tiva’s children compare to Russians until 11, after that these parameters as well as respiratory volumes increased in Russians, especially in boys. The time of simple sensor-motor responses was significantly lower in Russian children than in Tivas’s one in all age groups, but gender differences in 8-11-old children were not found. The level of memory and attention was significantly higher in Russian children of both genders and increased during ontogeny, but in girls the measured parameters were elevated compare to boys. To the time of their study beginning at the university the students of Tiva’s nationality had the lower parameters of physical development. To the end of education these differences between Tiva and Russian students decreased that indicated the effect of environment, especially of social and living conditions, on physical state of students.
