Differences between the effects of water Naftussya from fields of Truskavets’ and Pomyarky on the parameters of the EEG, HRV, immunity and metabolism

open access: yesJournal of Education, Health and Sport, 2019
Background. In previous studies involving subjects of both sexes with dysfunction of the neuroendocrine-immune complex, we found that the weekly use of Naftussya as Truskavets’ and Pomyarky deposits generally has the same effect on its parameters.The ...

Peculiarities of spectral parameters of EEG, HRV and routine parameters of immunity in patients with various levels of the entropy of EEG, HRV, immunocytogram and leukocytogram

open access: yesJournal of Education, Health and Sport, 2019
Background. We have previously shown that the entropy levels of spectral parameters of EEG and HRV as well as of Immunocytogram and Leukocytogram are well dispersed. The method of cluster analysis was the distribution of the observed contingent into four
