Guidelines in the use of the aquatic environment (swimming pool) in the musculoskeletal system rehabilitation in young representatives of the types of physical activity associated with the art of movement

In these guidelines we considered some special types of overuse injuries, associated mainly with increased joint ROM in lower extremities, for representatives of types of motor activity associated with the art of movement. Therefore, more and more researchers note that the physical activity in athletes' rehabilitation can be achieved using various physical exercises performed in the aquatic environment

Functional development of preschoolers of 5-6 y.o.: report II. Psychophysiologi-cal aspects of the organism

The paper characterizes the functional development of preschool children at the age of 5-6 years old. To assess the functional development of children of this age group in terms of physiological, behavioral, and subjective indica-tors, a set of rating scales was designed. These scales can be used to determine the level of functional development of preschoolers of the corresponding age and to identify chil-dren at risk (those with suboptimal development).

Psychophysiological characteristics of female medical students of the mid Ob region

The article presents the results of a research of the functional state of the central nervous system of medical students studying in a Northern region. The study was based on such parameters of variational chronoreflexometry as the latent period of a simple visual-motor reaction, CNS functional level, response level, the functional level of the system. The study involved 94 girls of 1-2 years of study; the average age of students was 19.7±1.59 years. The analysis of the CNS characteristics of female students re-vealed a slightly reduced level of performance, combined with signs of the inhibition process, fatigue and body stress-reaction to the hypocomfort climatogeographic educational environment. The reduced functional level of the central nervous system and the latent period of response to visual stimuli in most of the examined students indicated weaker perceptual processes and lower psychomotor control of the body activity.

Justification of sport and technical readiness standards of the students from the main department (groups of general physical preparedness with sport orientation in volleyball)

The aim of this work is to justify the standards of sport and technical readiness (STR) in 1-3-year students of the main department of non-athletes-students from General physical preparedness (GPP) groups with sport orientation (volleyball). Both 1st and 3rd year students showed no significant differences in STR indicators registered at the end of the fall and spring semesters. STR indicators reduced significantly from the end of 3rd by the end of 4th terms in 2nd year students. Separate STR standards for the 2nd year students in fall and spring semesters have been justified. SRT standards for the 1st and the 3rd year students have been clarified.

Physiological and hygienic aspects of the organization of distance learning dur-ing the pandemic COVID-19 (based on the results of a survey of parents and school-children)

A survey of parents and students conducted from April 24 to 27, 2020, during the full transition of Russian schoolchildren to distance learning, showed that in conditions of self-isolation during the COVID-19 pandemic, there was a significant increase in the duration of educational and extracurricular activities using electronic devices; more than 70 % of students complained that during distance learning, homework began to take longer, which is explained by the low efficiency of classes, the vast majority (about 90 % of cases) of children did not carry out preventive measures to reduce fatigue and counteract harmful factors associated with visual analyzer stress and hypodynamia. The stressful situation in the conditions of self-isolation and distance learning affected the psychosomatic state of schoolchildren.

Variability of sexual dimorphism of the main somatic indicators of newborns in connection with secular factor (according to materials of the russian federation and the former ussr at the time interval from the beginning of XX to the beginning of XXI century)

Long-term dynamics of the level of sexual dimorphism (SD) of body dimensions of newborns, embracing eight decades and inter- and intragroup variation, is under discussion. The study deals with a vast canvas of literary data – over 200 samples of newborns of each sex from former USSR and modern Russia through 1920-s till nowadays, including main anthropometric dimensions (body length and weight, chest and head girths). All samples are urban, the data is divided by decades, the number of each age/sex group as about 100 persons. Several levels of somatic variation were analysed: a) the whole data base above ethnic factor; b) only neighboring Slavonic groups; c) only Russian samples; d) regional Russian samples from Moscow and Kursk. The estimation of the level of SD is implemented using Kullback divergence, analogue of Makhalanobis distance. The results of meta-analysis, including the whole territory of Russia, witness to the definite secular sexual synchronism of dimension’s dynamics (increase of height/weight parameters and decrease of head girth), which results in very modest oscillations of SD around the level of 0,3 standard deviation. Still some secular decrease of SD is fixed for weight, due to more intensive increase of the parameter for girls, and for head girth, due to more intensive secular decrease of the parameter for boys. Some microsomisation of newborns is fixed in unfavorable war years 1940s and increase of SD due to greater decrease of the anthropometric parameters of girls (samples of Kursk). The same trend if fixed for Moscow newborns of 1960s, obviously above economic background, probably mediated by physical conditions of their mothers, who experienced economic depression of 1940s in their early childhood. Temporal fluctuations of SD level of main body dimensions of newborns keep within narrow interval 0,14-0,5 standard deviations, which does not exceed significant level of 0,3 standard deviations in the context of the study. This witnesses once again to the fact that the main factor of variation of newborns dimension is stabilizing selection, providing the stability of the dimensions of newborns of both sexes, as well as the level of sexual differences

Psychophysiological correlates of productivity of arrival attention of students

The psychophysiological correlates of the productivity of students' voluntary attention were investigated. It is shown that a group of students with an average level of productivity of voluntary attention have optimal indicators of heart rate variability. The proportion of persons with normal reactivity in response to the ortho test is significantly higher in them than in students with low indicators of the productivity of voluntary attention. In the group of students with low attention productivity, these indicators differ significantly from the norm. The results of monitoring the current state of students using the Luscher test showed that the balance of the processes of excitation and inhibition in the nervous system of the examined students and the indicators of their mental state have unsatisfactory dynamics. To correct the identified violations, it is proposed to use adaptive riding. Conditions have been created for training specialists in adaptive riding at the Faculty of Bioengineering and Veterinary Medicine of the DSTU.

Features of physical development of 5-6-year-old children from Reutov town, Moscow region

The paper presents and analyzes data on the study of anthropometric indicators of physical development of boys and girls aged 5-6 years old. The study re-sults indicate statistically significant sex differences identified in a number of parameters. It was shown that a significant part of the sample of 5-6-year-old children demonstrate main anthropometric indicators of physical development in accordance to the standards specified in the WHO documentation.

The purpose of the study is to improve the quality of assessment of students' coordination abilities in the process of physical education. The paper presents the results of testing the coordination abilities of the 4th-grade students of general educational organizations of the city of Ulyanovsk. The scientific novelty of the research lies in the development of indicative standards for assessing the coordination abilities of the students of the 4th grade. The following research methods were used: analysis of scientific and methodological literature on the research topic; pedagogical testing; mathematical and statistical processing of the obtained material. As a result of the study, data on the indicators of isolated coordination abilities of students of this age were obtained. Based on the data, there were developed indicative standards for assessing the coordination abilities of students of the 4th grade. The results of the study will help physical education teachers to conduct a comprehensive study of the coordination abilities of students, using a sufficient number of tests characterizing various aspects of their development.
