Peculiarities of the methodology, diagnostic value, and global recommendations for assessing exercise tolerance in children (literature review, own research)

Abstract

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.
