Differences in physical preparedness of different generations of females born by the migrants to Yugra

Aim. The purpose of the article is to study the characteristics of changes in physiological parameters and physical preparedness of different generations of females born by migrants to the Khanty-Mansi Autonomous District-Yugra and living there. Materials and methods. The study involved 60 females of which three groups were formed. Group 1 (n = 20) - females born in the regions of the middle zone of the Russian Federation who moved to the Khanty-Mansi Autonomous District-Yugra no more than 8 months ago. Group 2 (n = 20) - females born and permanently living in the Khanty-Mansi Autonomous District-Yugra, who are children (first generation) of migrants from the regions of the middle zone of the Russian Federation. Group 3 (n = 20) - females born and permanently living in the Khanty-Mansi Autonomous Okrug-Yugra, who are grandchildren (second generation) of migrants from the regions of the middle zone of the Russian Federation. All subjects were comparable in age. A comprehensive examination was carried out, including an assessment of physical preparedness, anthropometry, physiological parameters, physical activity. Results. No significant differences between the average values of anthropometric indicators were found in the examined subjects. In girls of groups 2 and 3 compared to group 1, a statistically significant increase in variation in body weight, body mass index and chest circumference was found. In group 3, significant differences were noted in the indicators of strength and speed-strength endurance, as well as speed and coordination of movement. The girls of group 1 had a significantly increased value of the Ruffier index compared to other groups. Conclusion. Group 1 had a lower training status of the cardiovascular system and adaptation to living conditions compared to groups 2 and 3. The level of physical preparedness was lower in the subjects of group 3.
