Purpose: to determine the impact of fitness classes with the priority use of roller skating on the morphofunctional state and physical fitness of schoolchildren in grades 5–6. Material & Methods: 194 children of 10–12 years old took part in the experiment, 90 of them were boys and 104 girls. The study was conducted on the basis of school number 269, Kiev with in-depth study of the French language. In the process of research, the following methods were applied: pedagogical (pedagogical experiment and observation); anthropometric; physiological (pulsometry, spirometry, functional tests) methods of mathematical statistics. Results: study shows that among pupils in grades 5–6, physical culture and fitness classes with priority use of roller skating means cause positive changes in the morphofunctional state and physical fitness. Significant improvements were found after 9 months of regular classes. Conclusion: fitness classes with the priority use of roller skating means have a positive effect on the morphofunctional state and physical fitness of students in grades 5–6. It was revealed that the indicators of the functional state (in particular, the cardiovascular and respiratory systems), physical fitness of students compared with the initial data are significantly higher (P(t)<0,01; P(t)<0,001).

Purpose: to investigate the dynamics of the types of reaction of the cardiovascular system to the dosed physical load using the Martine-Kushelevsky test and determine the functional state of the autonomic nervous system (ANS) using the Kerdo index of young women suffering from alimentary obesity under the influence of the developed comprehensive physical therapy program. Material & Methods: study was based on the clinical and functional examination of 50 women aged from 18 to 30 years old, patients with alimentary obesity I–II degree. Results: conducted and analyzed the state of the cardiovascular system on the dosed exercise with the help of the Martine-Kushelevsky and vegetative nervous system tests according to the Kerdo index. Conclusion: use of a physical therapy program, which includes a low-calorie diet, massage, therapeutic gymnastics with elements of sports-oriented aerobics, dosed walking in combination with breathing exercises taking into account the activity of the ANS, helps to normalize the functional state of the cardiovascular and autonomic nervous system.

Today, discussions are continuing on the effect of regular exercise in childhood in preventing bone loss in postmenopausal women, as well as the positive effect of physical exercise (PE) in the prevention of osteoporotic fractures in older age groups. Purpose: to assess risk factors associated with the level of physical activity (PA) in childhood and at the time of the examination in postmenopausal women with osteoporotic and vertebral body fractures. Material & Methods: in a one-time study examined 115 postmenopausal women aged 50–89 years. For analysis, the patients were divided into two groups: I (control) group – persons without any osteoporotic fractures in history (n=84), II (main) group – patients with vertebral body fractures at the level of the thoracic and lumbar spine (n=31). With the help of a specially developed questionnaire, the authors evaluated the characteristics of the PA of patients at different age periods of life and at the time of the survey. Results: no significant differences were found in the frequency and types of sports in childhood between groups, depending on the presence of vertebral body fractures. The majority of patients with vertebral fractures (85,7%) began regular exercises of PA in childhood with the age of 10 years (41,7% in the control group, p=0,04), and in 57,1% of individuals the duration of these exercises was 1–4 years and did not differ from the control group. The frequency, type and duration of physical activity classes and the duration of physical therapy procedures, as well as the level of daily physical activity, did not significantly differ in women depending on the presence of vertebral body fractures, although the proportion of people who worked on a regular basis in sections was significantly higher among patients with vertebral fractures (41,9%) compared with individuals without fractures (10,7%, p=0,0002). In addition, the proportion of women in the control group who were physically active 6 or more hours per day was significantly higher (14,3%) compared with the corresponding indicator of the main group (3,2%, р=0,04). Conclusion: women with vertebral fractures were more often practiced regularly in sections and less physically active than those without fractures. The duration, regularity and age of starting sports in childhood can affect the risk of vertebral fractures in postmenopausal women, requires further study.

Purpose: to establish the most significant indicators affecting the athletic performance of highly skilled swimmers during the overcoming of acyclic sections at 50, 100 and 200 meters in freestyle swimming. Material & Methods: theoretical analysis and synthesis of scientific and methodical literature, pedagogical observation, video filming, timekeeping, methods of mathematical statistics. The surveyed group (n=24) consisted of highly qualified swimmers (MS, MSIG, HMS), take on at a distance of 50, 100 and 200 meters freestyle. Results: the peculiarities of overcoming starting and turning sections at distances of 50, 100 and 200 meters of freestyle were studied. The level of significance of the underwater phase after performing starts and turns relative to the 15 m mark is established. The degree of correlation relationship between time, speed and distance for the underwater phase for the speed of passage of various segments of distance is revealed. Conclusion: improvement of starting and turning techniques, due to the increase in speed and distance of the underwater phase, is one of the reserves for the further growth of the skill of swimmers who specialize in freestyle.

Purpose: develop model characteristics of special physical readiness of Juvenile category athletes in acrobatic rock'n'roll. Material & Methods: theoretical analysis and synthesis of data of special scientific and methodical literature, pedagogical observation, pedagogical testing, pedagogical experiment, methods of mathematical statistics. The study involved 40 athletes (20 sports pairs of the category Juvenile). Results: model characteristics and evaluation standards of the level of special physical readiness of athletes of the Juvenal category from acrobatic rock'n'roll are determined. Conclusion: a system for assessing the level of special physical readiness of athletes can be used to optimize the training process in acrobatic rock'n'roll.
