Relevance. The most common indicators for assessing the effectiveness of health technologies are the cardiovascular performance of adolescents. At present, there is insufficient information on the quantitative substantiation of informativeness, prognostic and diagnostic significance of such indicators in the process of correction of functional and reserve capabilities of the cardiovascular system of adolescents. Purpose: To determine the levels of functional reserve of the heart according to the Rufier index and to study the physical performance of students aged 12-14 years of different medical groups. Materials and methods. 178 seventh-eighth-graders aged 12-14 (85 boys and 93 girls) were examined. All students voluntarily participated in this experiment, and the written consent of their parents was obtained. Physical performance was studied according to the parameters of the bicycle ergometric test PWC170. The division of students into medical groups was carried out according to the indicators of the level of functional and reserve capabilities of the cardiovascular system, conducted according to the Rufier index. Statistical analysis of the results was performed using the application package Statistica-V.10.0. The normality of the distribution was checked by the Kolmogorov-Smirnov test. The studied indicators are described by the median (Me) and 25, 75 percentiles. The relationships of the studied indicators were analyzed according to Spearman's rank correlation coefficients. To determine the reliability of differences in indicators used the criterion of Kraskel Wallis. Results. The main group included 13.5% of adolescents, the preparatory group – 35.4%, the special medical group – 51.1% of students. Among student-athletes, 25.9% of boys and 45.4% of girls belong to a special medical group. In school athletes, the correlations between the Rufier index and the PWC170 test are low and statistically insignificant. Indicators of physical performance in the range of 25-75 percentiles do not differ in different medical groups. This indicates that in a special medical group there are students with medium and high levels of physical fitness. Conclusions. The established age and gender differences in the functional reserve of the heart of schoolchildren determine the need to develop differentiated approaches to the assessment of the Rufier index. Physical performance in different medical groups varies in a fairly wide range. The division of students into medical groups according to the Rufier index does not reflect the level of physical performance of students and, accordingly, their real adaptive capabilities. Further studies are needed on the informativeness of using the Rufier test to divide students into medical groups.
Relevance. One of the human systems, which is particularly acutely affected by external environmental factors is the respiratory system. These disorders in adolescence are especially noticeable when intense and dramatic changes in the child's body on the path to biological maturity occur. Goal. The purpose of our study was to evaluate the functional indexes of the external respiration of adolescents of different medical groups of physical training. Materials and methods. The functionality of the respiratory system was evaluated by the results of pneumothography and respiratory retention. They were evaluated using mathematical statistics using the Medstat program (Yu.E.E., 2006). 76 middle school age pupils (38 boys and 38 girls) were surveyed, which belong to the preparatory group of physical training and 40 peers (20 boys and 20 girls) who attend the main physical education group. For comparison, normal indexes were used according to computer conclusions and scientific literature data Results. The normal performance of the VC according to the results of computer conclusions, registered in 42 % of pupils of the preparatory group of physical education, higher than the norm have 21 % of adolescents, 36 % of adolescents have significant violations of this index. According to the computer's conclusion, 52% of the subjects are characterized by extremely significant changes of FVC. A similar pattern is also noted for the index in the boys of this group. According to the results of computer findings 69% of pupils of the preparatory group have normal indexes of PEF, 21% have a higher then norm, 10% a slight decrease. The results of the functional test of Shtanger (delay in inhalation) showed that in the preparatory group this index is lower than the norm Volumetric indicators of the external respiration of pupils of the preparatory group in more than half of adolescents are significant changes. The volumetric indexes of such adolescents are significantly lower than the norm, by almost 1 liter. The rates of the respiratory system of the MEF 25, 50, 75% are lower than the norm by 1.5 - 2 times, and PEF does not differ from the norm. Conclusions. Indexes of external respiration in more than half of the examined pupils of the preparatory group were changed. The volumetric and flow rates of the respiratory system were significantly lower than the norm. A similar trend was followed by functional respiratory tests.
Relevance. The health of teenagers should be assessed not only by their morphometric data, but also by the functional state of the main organs and systems that provide adaptive reserve potential. Objective. The purpose of our study was to evaluate the functional capabilities of the cardiovascular system of teenagers according to biomechanical indexes of blood circulation. Methods and materials. 272 teenagers aged 13–14 (176 boys and 96 girls) participated in the study. Among the boys, there are 104 pupils of the basic medical group of physical education and 72 of the preparatory group (2nd health group). There were 48 primary and 48 preparatory group pupils among the girls. The results of Kubicek rheography and rheovasography were used to study the biomechanical parameters of the cardiovascular system. They were evaluated using the methods of mathematical statistics (the MedStat program (Ye. Lyakh, 2006)). Results. There were no any statistically significant differences between most of the rheovasographic parameters of the students of the preparatory and basic medical groups of physical education. Instead, there are certain distinctive features of the peripheral blood flow of pupils of the preparatory group of physical education (with reduced functional capabilities). Thus, the , indexes of the rapid filling timing in the pupils of the preparatory group of physical education are lower than in the main group.In the boys of the preparatory group of physical education on both hands and in the girls of this group on the left hand, the blood flow time for the forearms is slightly increased. Greater deviations from the norm for the amplitude of rheograms were found in pupils of the preparatory group of physical education. The number of pupils with asymmetric blood supply to the forearms in the preparatory group of physical education is more than in the main group. A decrease in the blood supply of the vessels of the forearms is registered more often in teenagers who are assigned to the preparatory group of physical education. In the boys of the preparatory group of physical education, the blood vessels of the shins are worse. Conclusions. Some distinctive features for the state of peripheral blood flow of teenagers in the preparatory group of physical education were revealed. Thus, the indexes of the rapid filling timing, the amplitude of the rheograms were lower, and the time of propagation of the pulse wave was higher than normal. Asymmetry and decreased blood flow in the vessels of the upper and lower extremities were noted in most teenagers with impaired
Relevance. Physical and mental health indicators play a major role in assessing patients' quality of life. The quality of life deteriorates with the development of post-traumatic stress disorders (PTSD), and it directly affects patients' health. Objective: to investigate changes in indicators of quality of life among patients with PTSD. Materials and methods. 22 young patients participated in the study. The MOS SF-36 International Quality of Life Questionnaire and the Mississippi Posttraumatic Stress Disorder Rating Scale (civilian version) have been used. Results. According to the results of the Mississippi Scale, the patients were divided into three groups: 1 (n=4) – without PTSD symptoms, 2 (n=13) – with mental disorders, and 3 (n=5) – with PTSD symptoms. In each of the above mentioned groups, the MOS SF-36 quality of life test has been conducted. According to its results, it was determined that group 2 had lower quality of life indicators (physical and mental health components) compared to the first group, but higher compared to the third group. Conclusion. Manifestations of PTSD directly affect the quality of life of patients. Patients with PTSD and mental disorders reported lower indicators of physical and mental components of health.
The data on indicators of psychological and physical components of health as the life of persons with comorbid states, who have taken the course of rehabilitation using the means of physical therapy, are given. Generally accepted method for calculating the components of the MOS SF-36 application form was applied in the research. It has been established that regardless of the type of chronic comorbid diseases or states, the physical component of health (PCS) is higher compared to the psychological component of health (MCS) in the integral indicator of quality of life. An individually compiled program of physical therapy, as a basic component of rehabilitation, has been positively reflected on the quality of life by increasing the psychological health indicator by 20.9%. An objective is the analysis of the dynamics of the components of the life quality in the process of 14-day program of physical therapy in patients with comorbid states. Materials and methods. 34 students of Lesia Ukrainka Volyn National University with various combinations of chronic diseases and states were researched. They have taken a 14-day rehabilitation course on the basis of the Western Rehabilitation and Sports Center of the National Committee of Sports of Disabled Persons of Ukraine during a rehabilitation meeting of persons with disabilities. The quality of life was evaluated by the method of two-time anonymous interviews using Medical Outome Study Short Form-36 (MOS SF-36). The statistical data processing was carried out using the MedStat program. The results. During the initial interview it was found out that among the components of physical and psychological aspects of health, the RP indicators were reflected most negatively on the life quality which characterize the activities conditioned by the physical state, operation at work, at home, and the VT indicator, which reflects vital activity as well. Focused 14-day rehabilitation program contributed to improve their values more than a third part of previous one. The PF indicator, that certifies the physical activity of the person, refers to the components that increase the general indicator of life quality of the students with comorbid states. The SF indicator refers to these components as well. It certifies the social activities of the above mentioned persons. Analyzing the dynamics of all indicators of life quality in the process of rehabilitation meeting, it follows that the range of changes varies from 4.2% to 41.7%. Regarding correlation links between the indicators of life quality, there were identified three direct links of moderate force at the beginning of the research: between PF and RE (R = 0.66); between GH and RE (R = 0.53) indicators; between VT and MH indicators (R = 0.62). After the rehabilitation program using physical therapy, a significant negative link between the values of BP and PF (R = -0.64) has been formed. Positive correlation of moderate force appeared between the GH and RP indicators (R = 0.53); between the MH and RP indicator (R = 0.59), GH (R = 0.58), VT (R = 0.63). Conclusions. The comorbid state is negatively reflected on the quality of life, on the perception of capabilities and restrictions. The two-week rehabilitation course using physical therapy means allowed participants of the research to change the perception of their state, capabilities and restrictions in everyday life.
