Abstract

Background. Typically, the step test is used to assess the physical performance that is determined by the condition of the cardio-respiratory system. The latter, in turn, is associated with the nervous, endocrine and immune systems, which collectively determine the level of adaptation of the body. The purpose of this study is to analyze the effect on the step test of natural adaptogens and associated changes in a number of parameters of cardio-respiratory, autonomic nervous and immune systems and metabolism. Material and methods. The target was 80 children of both sexes, ages 10-17, arriving at the clinical sanatorium "Dzherelo" of Truskavets spa from radionuclide contaminated territories. The main subject of the study was the  Popovych’s step test. State of autonomous nervous and immune systems was assessed as well as others functional and metabolic tests. Results. The contingent surveyed was retrospectively divided into three qualitatively distinct groups. The largest group (53,7%) was the group of children with initially reduced or normal levels of Popovych’s Step Test Index (PSI), in which it increased. However, in 28,8% of children PSI remained stable at different initial levels, and in 17,5% even decreased, without falling below the lower limit of normal. Discriminant analysis was subsequently applied to identify constellations of parameters that change are characteristic of each cluster. The program selected as characteristic changes in 2 parameters of autonomous nervous system, 2 functional, 4 metabolic and 3 immune parameters as well as blood trombocytes level. The correct classification of the positive actotropic effect is 93,0%; neutral 65,2%; negative 64,3%, and total correctness is 80,0%. Conclusion. Balneotherapy causes multivariate changes in Popopvych’s step test, which accompanied by characteristic changes in certain parameters of autonomous nervous and immune systems as well as others functional and metabolic tests.
