“…Одним із методів клінічної діагностики стану здоров'я людини, що дає можливість визначити та комплексно проаналізувати ступінь функціональних і адаптаційних можливостей організму, зокрема серцево-судинної та дихальної систем, є оцінка толерантності до фізичного навантаження (ТФН). Діагностична цінність оцінки ТФН полягає в тому, що за її допомогою можна проаналізувати вплив різноманітних патогенетичних чинників захворювань на постморбідний стан здоров'я, якість життя дитини чи підлітка [2].…”

An important and understudied problem is the state of health of children and adolescents who have experienced acute respiratory diseases or suffer from chronic diseases. Suffering from COVID-19 and post-COVID-19 syndrome, pneumonia are complex pathological conditions that significantly affect the functional capabilities of the child’s body and quality of life. Obesity, which is also an important medical and social problem, has no less impact on health. The purpose of the work is to summarize the data from the literature about the value of exercise tests in children with postcovid syndrome, after pneumonia of various etiologies, and obesity; modern aspects for assessing exercise tolerance. It is worth noting that nowadays screening programs for examining the health of children, aimed at prevention and early detection of pathological changes, play an important role. One of these methods of diagnosis, which makes it possible to determine and comprehensively analyze the body’s functional capabilities, is the assessment of exercise tolerance. The diagnostic value of analyzing the tolerance level lies in assessing the impact of various pathological conditions on the child’s health, and quality of life. The obtained results can be used to develop rehabilitation measures to eliminate the symptoms of acute diseases and improve the quality ofi fle. Tests with dosed physical exertion are used to assess exercise tolerance. The «gold standard» of the technique is cardiopulmonary exercise testing. However, world tolerance assessment guidelines include the use of other types of tests, such as office and field tests. The «gold standard» for assessing tolerance is the determination of the maximum oxygen consumption (VO2max), which characterizes the maximum amount of oxygen that is absorbed and used by the body during intense physical exertion involving a large possible part of the muscles. Also, during exercise tests, heart rate, blood pressure, and electrocardiogram recording are monitored, which creates significant diagnostic search opportunities for the pediatrician.

Background. Juvenile idiopathic arthritis (JIA) is the most common rheumatological disease of childhood (1 : 1,000 children), which involves many organs and systems, primarily cardiovascular, with the gradual development of chronic heart failure. As you know, when the functional capacity of the heart decreases, a cascade of reactions of the neurohumoral regulation system is triggered and, first of all, the sympathoadrenal system is activated with an increase in the catecholamine production, the development of tachycardia. Due to this, the level of brain natriuretic peptide in the blood is increased. In children, chronic heart failure is asymptomatic. Therefore, determining tolerance to physical exertion plays an important role in its diagnosis. The purpose was to determine the functional state of the cardiovascular system and the tolerance to physical exertion in adolescents with JIA, taking into account the level of catecholamine excretion in the daily urine and the level of natriuretic peptide in the blood. Materials and methods. Fifty-six patients with JIA aged 12–17 years (13.28 ± 0.38 years) were examined. The control group consisted of 46 apparently healthy peers of the corresponding age. A heart ultrasound was performed to establish the functional state of the myocardium. To study tolerance to physical exertion, a six-minute walk test was performed with calculation of Kerdo index before and after the test. The level of catecholamine excretion in the urine and the level of natriuretic peptide in the blood were studied. Results. Patients with juvenile idiopathic arthritis had early signs of right ventricular myocardial systolic dysfunction (a decrease in the right ventricular ejection fraction). At the same time, we detected a decrease in the catecholamine level and an increase in the content of natriuretic peptide, which has a neuromodulatory effect at different levels of the sympathoadrenal system. Conclusions. Activation of the sympathetic division of the autonomic nervous system (increased Kerdo index) in patients with juvenile idiopathic arthritis does not ensure the effectiveness of minimal physical exertion in a six-minute walk test.

Assessment of exercise tolerance is one of the methods for clinical diagnosis of health status, which makes it possible to determine and comprehensively analyze the degree of physical fitness of a patient, his ability to tolerate physical exertion, and the adaptation capabilities of the body. The level of exercise tolerance plays a major role in assessing health status and quality of life of children and adolescents, as it depends on a whole set of factors, namely: the functional properties of the cardiovascular, respiratory, and musculoskeletal systems and the level of physical fitness. Tests with dosed physical activity are used to assess exercise tolerance. The diagnostic value of methods for evaluating exercise tolerance consists in the possibility of constant monitoring of heart rate, blood pressure, recording of an electrocardiogram, fixation of the level of blood oxygen saturation, determination of peak or maximum oxygen consumption obtained by direct and indirect methods during the test. The interpretation of the obtained results creates significant opportunities in terms of the diagnostic search for a pediatrician. The purpose of the work is to summarize the literature data about peculiarities of the tests with dosed physical activity, their diagnostic value, and global recommendations for assessing exercise tolerance in children, to evaluate the results of own research.
