Comprehensive assessment of physical fitness in children - representatives of different ethnic groups living in Khanty-Mansi autonomous okrug - yugra

Materials and Methods. The authors examined 479 children and distinguished two groups: Khanty and descendants of the alien population in the 1st and 2nd generations. The authors studied their anthropometric measures and physical fitness indices. Statistical data processing was carried out using Statistica 10.0. Results. Assessment of anthropometric measures in children - representatives of different ethnic groups living on the territory of the Khanty-Mansi Autonomous Okrug-Yugra - made it possible to identify peculiarities of their physical fitness. It was found that Khanty children were characterized by smaller anthropometric measures compared to descendants of the alien population, as well as compared to Nenets children living in the Yamalo-Nenets Autonomous Okrug. Khanty girls and their peers from the group of descendants of the alien population showed a tendency towards the convergence of values in terms of body weight and chest capacity since the age of 14. The picture was quite different for boys: since the age of 14 and onward, the differences in anthropometric measures increased. In Khanty boys, a growth spurt was observed at the same time as in boys, who were descendants of the alien population, and a year later than in Nenets children; in girls it was observed 1-2 years earlier than in the comparison groups. The first and second intersection of growth lines was noted somewhat earlier (at the age of 10 and 14) than in the descendants of the alien population (at the age of 12 and 15). High physical fitness was more common among Khanty girls (35.9 %) compared with the descendants of the alien population (21.9 %). Conclusion. A comprehensive assessment of physical fitness in children aged 8-17 years living in the Khanty-Mansi Autonomous Okrug-Yugra indicates the need to develop regional standards of physical fitness in regard to the ethnicity.
