Background. In this paper, we present the results of the study concerning body development and body composition parameters dependency. Material and methods. The monitored sample consisted of 78 probands aged of 4 – 11 years: group I, 4 – 5 year-olds (13 probands) 5.17 ±0.52 years; group II, 6 – 7 year-olds (30 probands) 6.99 ±0.52 years; group III, 8 – 9 year-olds (25 probands) 8.8 ±0.52 years; group IV, 10 – 11 year-olds (10 probands) 10.92 ±0.53 years. To diagnose parameters of body composition the InBody 120 device was used. Results. As for the parameters of body composition, a rising linear trend was recorded with increasing age. Statistically significant (p < 0.05) values were found between age groups in body height (p = 3.76E-24), body weight (p = 4.65E-16), quantity of fat mass (p = 0.0475), quantity of skeletal muscles (p = 1.31E-20), total quantity of water in body (p = 2.23E-20), quantity of proteins (p = 1.83E-20), quantity of minerals (p = 2.06E-19) and in the level of basal metabolism (p = 1.77E-20). Conclusions. Our results of body height and body weight correspond to those obtained in national anthropometric measurements. BMI values respond to the developmental trends, but they differ in the achieved values of comparable age groups as our probands have achieved lower values than the Slovak population.
The article is devoted to the study of asymmetry in physical development of arm wrestling athletes at the stage of sports perfection. It presents the results of a pedagogical experiment with the use of static motor-cognitive tests and stabilometry in the detection of asymmetry and proves the effectiveness of the developed system of physical training, based on the achieved improvements of the indicators of equilibrium function of arm wrestlers compared to the standard training system.
The aim of this study was to investigate the physical activity, the basic parameters of physical development, and eating habits of students from Ukraine. The research method of diagnostic survey using a IPAQ questionnaire  and nutrition questionnaire was carried out in 2013 among 2 125 students, for 60.8% of women and 39.2% men. As a result of studies beneficial indicators of total physical activity were demonstrated, with higher physical activity of persons who have sufficient amount of free time. The level of BMI indicator is in the majority of students at a normal level. The amount and frequency of meals is a sign of positive healthy behaviors. Also the disadvantageous behaviors occur, such as avoidance and loss of control over eating and induction of vomiting for the sake of one’s body.
Swimming is an Olympic kind of sport in which sportsmen demonstrate their technical skills and speed and also set worldwide records. The chosen sport combines the possibility of harmonious development of the body, wellbeing orientation, and emotionality. The predominant orientation of the training process in the groups of initial training is the training and improvement of swimming skills in sporting ways, the development of overall endurance, flexibility and speed of movement. The goal is to improve the technique of development of physical qualities of 5-6 year-old swimmers at the stage of initial training. Organization of the research. We divided a school year symbolically into 2 semesters. There was an indepth study of swimming techniques like crawl and backstroke and familiarization with the elements of swimming in a dolphin way during the first half of the year (October-December). The second half (January-May) was devoted to improving such swimming techniques as crawl and backstroke. Results. It is important to determine the target indicators - the final and intermediate (current), which can be judged on the implementation of tasks; develop a general scheme for constructing a training process; determine the dynamics of training parameters and loads, as well as the system of restoration of work, aimed at achieving the main and intermediate goals in order to maximize the implementation of our methodology. As a result, the best growth of the results was in the tests: flexion and unbending of the hands in lying position: Control Group (hereinafter CG) – 9,71%; Experimental Group (hereinafter EG) – 15, 21%; body inclination forward in sitting position: CG – by 6,34%; EG – 12,62%; burpee: CG – 8,65%; EG – 16,34%; high jump: CG – 8,37%; EG – 14,03%. Conclusions. The obtained results testify the effectiveness of our improved methodology, which aim is to use specially selected exercises and has an alternative percentage distribution of all components of sports training.
The aim of the research was to diagnose chosen individual factors of adolescents’ physical development (motor skills, physical fitness, motor activity needs) and their influence on their actual level of physical activity in their leisure time. The subjects of the research were students of Cracow’s junior high schools. The probability sample of 295 girls and 329 boys were examined. The method used was a survey. The results of the examinations showed that the chosen individual factors had an influence on the actual level of physical activity in their leisure time. The boys’ motor skills (in contrast with the rest of the factors) correlated the least with the increase of the actual level of physical activity in leisure time, and in case of the girls, they did not correlate at all. Youngsters’ individual predispositions to undertake physical activity in their free time were at a medium-high level. Nevertheless, their internalization did not take place because more than a half of the subjects undertook physical activities at a low level (51.0%) or not at all (7.4%).
Przedstawiono wyniki badań dotyczące poziomu rozwoju fizycznego oraz zróżnicowania wybranych zachowań zdrowotnych uczniów szkół ponadgimnazjalnych w zależności od poziomu wykształcenia ich matek
W większości domów dziecka zapewniono wychowankom dobre warunki do nauki i wypoczynku. Zanotowane w niektórych placówkach nieprawidłowości wymagają podjęcia działań dla ich eliminowania w celu zabezpieczenia podopiecznym optymalnych warunków dla rozwoju psychofizycznego.
W artykule przedstawiono główne problemy żywienia dzieci szkolnych w Polsce na tle ogólnej sytuacji ekonomicznej kraju, zwracając uwagę na wskaźniki rozwoju fizycznego. Wykazano najczęściej popełniane błędy żywieniowe, ich skutki zdrowotne oraz wpływ na postępy w nauce. Podano też przyczyny obserwowanych zjawisk. W podsumowaniu wskazano działania w kierunku rozwiązania problemów żywienia tej grupy populacyjnej.
