Introduction. Properly organized process and program content of physical education of schoolchildren living in the conditions of the Far North, based on the negative factors of the local living environment, will contribute to the harmonious and progressive physical development of children in this unfavorable region for life. One of the important indicators of the development of the musculoskeletal system of children is the mobility of the spine.
The purpose of the study is to analyze the mobility of the vertebral part of schoolchildren living in the conditions of the Far North.
Methodology and organization of the study. The experiment was attended by schoolchildren of Norilsk, Krasnoyarsk Territory from 1st to 11th grades, the sample size was 1000 people. To assess the mobility of the vertebral region, a control test was used – "Leaning forward from a sitting position with the legs together, the hands move palms down while leaning forward along the trunk, where it is necessary to press the trunk as close as possible to the knees of the legs. It is forbidden to grab the legs with your hands." If the fingers are up to the heels, then these are the results with a sign (–), if behind the heels – the results with a sign (+).
Research results and conclusions. The measurements of the mobility of the vertebral part of schoolchildren of grades 1-11 living in the conditions of the Far North showed the following:
– the girls: 1st grade – 4.4 cm; 2nd grade ‑ 6.1 cm; 3rd grade – 1.0 cm; 4th grade ‑ 5.4 cm; 5th grade – 3.9 cm; 6th grade - 2.6 cm; 7th grade – 8.3 cm; 8th grade – (-3.5) cm; 9th grade – 10.7 cm; 10th grade ‑ 12.1 cm and 11th grade – 9.8 cm;
– the boys: 1st grade – 3.5 cm; 2nd grade ‑ 1.4 cm; 3rd grade – (-3) cm; 4th grade ‑ 3.1 cm; 5th grade – 0.5 cm; 6th grade – (-0.2) cm; 7th grade - 4.3 cm; 8th grade – (-2.1) cm; 9th grade ‑ (-1.0) cm; 10th grade – 6.3 cm and 11th grade ‑ 5.3 cm.
Analyzing the results obtained, it should be noted that in girls, the development of mobility of the vertebral region is observed from the 7th to the 11th grades, the lowest mobility indicators were found in the 3rd, 6th and 8th grades. In boys, the highest rates of spinal mobility were found in grades 7, 10 and 11. Low mobility indicators in grades 2, 3, 5, 8.
Conclusion. These results show that, in general, children living in the conditions of the Far North do not have enough mobility of the vertebral region in physical education lessons. In this connection, it is necessary to develop corrective additional pedagogical measures aimed at the systematic formation of the mobility of the vertebral region of children living in unfavorable living conditions of the Far North.
