Assessment of physical development, functional state and physical readiness of students with deficiency of body weight

There are numerous publications in the literature reporting physical development and motor performances of children of different ages based on sex and various environmental factors. However, there are not many publications on the birth season effect. The aim of the study was to evaluate the differences among children in physical development and motor performances based on age and birth season. Physical development described by body height and body weight, in addition to motor performance indicators including the twenty-metre dash, standing broad jump, six minutes of continuous running, throwing with a stuffed ball, and obstacle race-tests were studied. The survey included the participation of 426 girls. From the group the seven-, eight-, and nine-year olds numbered 148, 191, and 87 respectively. The group of girls who were born in winter, spring, summer and autumn numbered 114, 110, 89 and119 respectively. The tested data were evaluated with unitrate analyses of variance using SPSS statistical package. Mean value, standard error, standard deviation and coefficient of variation were calculated. The significance of differences between mean values was evaluated using “t” test. Differences with an error below 5% were considered to be significant. Furthermore, a correlation analysis was used to evaluate the relationship between season of birth, body development and motor-related performance data. Age, body height, body weight, throwing a stuffed ball in one hand, twenty-metre dash, six minutes of continuous running, and obstacle race-test are interdependent variables of development and motor performances of young girls of this age. Data from the study results show that the children group included in the tests was quite homogenous in body height, but heterogeneous in body weight and motor performances. Physical development and four of the five evaluated sport skills were affected by the birth season. Development and motor performances of the summer- and autumn-born girls are generally better than those born in winter or spring. Differences are significant except for the obstacle race-test. Age, body height, body weight, throwing with a stuffed ball in one hand, twentymetre dash, six minutes of continuous running, and the obstacle race-test seem to be interdependent variables of development and motor performances of young girls of this age.

Aim. To investigate physical development of children in Voronezh region in different age groups in 2011-2014 in comparison with the regional studies data in 1997-1999. Methods. The study was performed on 5644 children aged 1-18 years of health groups I and II in comparison with the data of 10 247 children aged 1-14 years examined in 1997-1999. Body height, weight and body mass index Z-scores, calculated using WHO AnthroPlus software, were evaluated. Results. Children’s Z-score values for body height in 2011-2014 were higher than in 1997-1999 in all age groups and at the age of 1-9 years these values exceeded World Health Organization (WHO) standards. Girls’ height approached the standards in 10-14 and 15-18 years, and boys’ height - in 15-18 years. Body weight of children aged 2-8 years was higher than the regional data in 1997-1999 and WHO standards approaching them at the age of 9. Body mass index increase compared to WHO standards was revealed in children aged 1-4 years (p=0.000), and in 2011-2014 the reported differences were less prominent than in 1997-1999. In 2011-2014 among 15-18-years-old girls the shift of body mass index values to the lack of body weight was noted, in 1997-1999 the same changes were found out for 10-14-years-old girls. Conclusion. In 2011-2014 specific attention was required to be paid to physical development of children at the age from 1 to 4 years due to overweight risk of and girls aged 15-18 years due to probable underweight risk.

Aim. To study the features of the morphofunctional development of the Kazakh nationals of the first year of the M. Kozybaev North Kazakhstan State University arrived for training from the northern and southern regions of Kazakhstan with the goal of developing preventive measures to reduce the adaptive stress to university education. Material and methods. The study involved 400 first-year students 17-18 years old, of both genders, studying at different faculties of the M. Kozybaev North Kazakhstan State University (200 girls and 200 boys) who arrived from the northern and southern regions of the republic. Standard methods of determining anthropometric and functional indices, estimating the adaptive potential and the level of physical health were used. The resulting material is processed by the methods of ANOVA statistical methods. Results. Indices of physical development (length, body weight, chest circumference, Quetelet, Pinje and stenius indices) were shown to be within the age-gender norms, but a comparative assessment of physical health of students showed significant differences in the anthropometric and physiological state depending on the previous area of residence. Thus, the length of growth in northerners was higher than that of southerners. The indices of body weight, chest circumference, and the Quetelet index are higher in representatives of the southern regions. By the type of body build, among the girls and boys hypersthenics predominated in the southern region, normostenics - in the northern region. At the same time, with an increase in the constitution, the absolute and relative values of force indices and the vital index increased. At the same time, students in the southern region had a lower functional reserve of the heart, determined by the magnitude of the double product, the heart rate, and blood pressure. For students of the northerners of both genders, satisfactory adaptation (1st “level of health”) is typical, whereas representatives of the Southern Region had a lower level of adaptive potential, which corresponded to the state of exertion of adaptation mechanisms. Conclusion. Comparative evaluation of morpho-functional indices of the body of students of adolescence revealed features of body size, type of constitution, functional reserves of the cardiorespiratory system depending on the previous region of residence. The data obtained can be used to compile standards for the physical development of young people of different regions of the republic and the development of health programs to reduce adaptive stress.

The article provides the results of determining the level of physical development of the 1th-2nd course students of design specialties of the College of Construction, Architecture and Design. The physical development of students was determined by indicators of harmony of the bodybuilding (Kettle index 2), functional state of the cardiovascular system (Ruffier index), and respiratory system (Stange test). Length and weight of the body, heart rate, breathing delay time were measured. As a result of the researches, the “average” level of the physical development is determined in the 1th-2nd course girls and “sufficient” - in boys. Thus, mass-growth indicators of students according to the calculation of Kettle 2 index, both boys and girls correspond to the assessment of 5 points, which indicates a harmonious physique of students; indicators of the functioning of the cardiovascular system (Ruffier Index) of 1st year boys and the 2nd year students make 2 points, which corresponds to the ”below average” level, and the results of the 1st year girls equal to the assessment of 3 points, “average” level; indicators of the functional state of the respiratory system (Stange test) of boys of the 1th-2nd course correspond to the assessment of 4 points (“above the average” level), and girls of both courses - 3 points (“average” level). In the age and gender aspects, physical development indicators, in general, don’t significantly differ with the general tendency to increase results with age and the dominance of boys over such in girls. The exception is the Ruffier index, where there is an opposite trend - the results decrease with age in girls and they are higher than in boys. Thus, the results of the research indicate the feasibility of introducing the 1th-2nd course students of professional pre-high education of special physical exercises into the process of physical education to improve the functional state of the cardiovascular and respiratory systems.

Purpose of the study: To register the dynamics of the basic parameters of the physical development of children from the fourth preparatory group, as a result of the implementation of an enriched educational content in physical culture pedagogical situations. 54 girls and 67 boys were investigated and measured twice – at the beginning and at the end of the pedagogical experiment. Anthropometric parameters assessed: height, body weight, chest circumference. Methods: Theoretical analysis, pedagogical experiment, anthropometry, statistical methods. Results: Height: the highest increase in that parameter was found in the Experimental Group of boys and the smallest one – in girls of the Control group. Body weight: boys from the EG showed the highest increase, while the lowest one was found in boys from CG. Chest circumference: the greatest increase was measured in CG of, while the smallest one in the EG of girls. In conclusion, we can underline that the changes in the anthropometric parameters are due both to the laws of biological developments of children at that age, as well as to the applied enriched educational content.

Preserving and strengthening the health of orphaned children and children left without parental care is of great medical, social and public significance. The aim of the study. Assess the health status of adolescents without parental care. Material and methods. The object of the study was teenagers left without parental care (adolescents from 10 to 18 years old). The total sample size was 2,499 adolescents. Assessment of physical development was carried out on the hardware-software complex "Health-Express". This high-tech equipment, developed by the "Kazakh-Russian Medical University". Results and discussion. The authors have shown that at the present stage, there are negative trends in the number of children with disharmonious physical development due to lack of body length. For example, the frequency of identified disharmonious physical development in the age group 10-14 years was 71.8% and in the first childhood group 28.2%. The main reason for disharmonious physical development was a growth deficiency and moderate body weight deficiency. Conclusions. The main reason for the disharmonious physical development of adolescents left without parental care was a deficit in height and a moderate deficit in body weight. Keywords: physical development, teenagers, orphans, "Health-Express", body mass index, body length.
