The article presents results of an empirical study of the age dynamics of the social situation of develop¬ment in primary school students in inclusive education. The study sample consisted of 328 children aged from 7 to 11, including 18 children with SEN, studying in two inclusive schools in Moscow. The hypothesis of the study was that the characteristics of the objective and subjective aspects of the social situation of chil¬dren’s development change in accordance with the two phases of primary school age. The characteristics of the social situation of the development of children were measured using the “Sociometry” method and two projective methods: “Color Test of Relationship” and “Sentence Completion Test”. The age dynamics is ob¬served in changes in the social position and the system of orienting images of primary school students. The significant differences between the distribution of sociometric statuses of students in inclusive classes and the age standard obtained in the conditions of traditional education were found. The results of the study reveal the specificity of elementary school students’ development in conditions of inclusive education.

Objective: to assess the constitutional features of the age dynamics of secondary sexual characteristics and functional parameters of city schoolchildren in the age range of 7–17 years.Materials and methods. The objects of the study were schoolchildren aged 7–17. The stages of the expression of secondary sexual characteristics were determined visually according to the scheme by J.M. Tanner. The functional parameters of the examined schoolchildren were assessed using the methods of dynamometry, spirometry; blood pressure and heart rates, as well as the time of simple sensorimotor reactions were measured.Results. As a result of the performed studies, it has been found that representatives of the hypersomnic types are ahead of other types to reveal the first stages of secondary sexual characteristics. Schoolchildren with the leptosomic morphotypes due to higher rates of their development have reached the definitive stages by the same age as those with the hypersomnic variants. The intensity of age-related changes in functional parameters (strength qualities, circulatory and respiratory systems, nervous system) in the studied objects depends on their body type.Conclusion. The stage and rate of puberty, as well as the development of functional parameters in city schoolchildren depends on their somatotype.

The paper presents the research results on the physical development of high school girls with different body types. It was found that schoolgirls of 14-17 years of astheno-thoracic somatotype were inferior in terms of girth values to their peers who had a muscular-digestive body type. But they have the longest body length. The values of A-T somatotype change most rapidly in most indicators. They have a later development. At the highest rate during this age period the lungs grow at the fastest pace.

Purpose — to identify patterns of age dynamics of functional and motor fitness girls eighth and ninth grades.Material and methods. To achieve the objectives adopted the following methods: analysis of scientific literature, teacher testing and treatment methods of mathematical statistics research results. In the study involved 14 dyvchat class 8, 14 — 9 class.Conclusions. Analysis of the test results shows that statistically significant differences between girls 8 and 9 classes in functional samples was observed. For the functional state of respiration and circulation girls 8 and 9 classes are rated as healthy untrained.Girls 9 classes show statistically significantly better results in tests for speed strength, static display of strength and motor coordination (tests 8 «Long jump from place, see» 7 «Height in folded hands, p ‘and 2’ Evaluation of temporal parameters movement, with error «).Standardized canonical discriminant function coefficients can determine the value contribution of variables in the function result. With the largest contribution to the canonical function variables are 6, 10 and 7: the higher the value of these variables, the more important functions. The foregoing indicates to assess the functional and motor fitness of students grades 8—9 using the proposed battery of tests.Structural factors canonical discriminant function shows that feature most significantly associated with 7, 8 and 2 variables: the more attention is paid to static, the actual strength and coordination training, the greater the likelihood of increasing the level of functional and motor fitness girls 8—9 grades.100.0% initial observations are grouped correctly classified. Thus, the canonical discriminant function can be used for evaluation and prediction of functional and motor fitness girls 8—9 grades.
