COMPLEX CHARACTERISTIC OF FUNCTIONAL STATE OF YOUNGER SCHOOLCHILDREN ORGANISM AT THE INITIAL STAGE OF REALIZATION OF THE DIFFERENTIATED APPROACH TO PHYSICAL EDU-CATION ORGANIZATION

Abstract

This study of the values of functional indices of cardiovascular, respiratory, muscular-ligament systems and vestibular analyzer in 146 junior schoolchildren (68 boys and 78 girls) 8-9 years was conducted for the purpose of a complex comparative characteristic of the functional status of the organism of children of different gender at the initial stage of implementation of a differentiated approach to the organization of physical education. The analysis of the results revealed differences between boys and girls in the in-spiratory breath delay (23.3 ± 1.0 s and 19.8 ± 0.7 s, respectively; p < 0.05), the vital capacity of lungs (1 532 ± 45 ml and 1 406 ± 34 ml, respectively; p < 0.05), the level of static balancing (4.3 ± 0.3 s, 6.6 ± 0.5 s, respectively; p < 0.05) and stato-kinetic stability (5.00 ± 0.20 rev and 5.64 ± 0.20 rev, re-spectively; p < 0.05), left hand muscle strength (8.4 ± 0.2 kg and 7.7 ± 0.2 kg, respectively; p < 0.05). Functional muscular testing showed that the muscles and ligaments of the neck, shoulder girdle, pecto-ral muscles and muscles of the trunk from boys are more often in the enslaved state than in girls. The tests for the condition’s evaluation of the muscles and ligaments of the neck, shoulder girdle, pectoral muscles was not performed by 27.9 % of boys and 7.7 % of girls (p < 0.05; test 2); 48.5 % of boys and 15.4 % of girls (p < 0.05; test 1); muscles and ligaments of the trunk - 10.3 % of boys and 1.3 % of girls, p < 0.05; muscles and ligaments of the pelvis and lower limbs – 1.5 % of boys and 3.8 % of girls, p > 0.05. The results demonstrate the features of functional status of the organism of children of primary school age of different gender and can be used for hygienic substantiation of the differential approach to the organization of their physical education.
