Abstract
Using the roentgen-fluorescent analysis, we found mostly below-norm contents of iron and copper in stable tissue samples (hairs) of 18- to 20-year-old sportsmen (university students). Correlations of the results of such analysis with sets of indices characterizing the state of the CNS (parameters of background EEG and of evoked/event-related EEG potentials), that of the cardiovascular system (CVS, data of electrocardiography and rheography), and of the mechanisms providing autonomic regulation of the latter system (indices of cardiointervalography) were calculated. According to the number of significant correlations (0.44 < r < 0.56) and their intensity, we found that the content of copper is more significant for the indices characterizing functioning of the CNS, especially for those of EEG phenomena related to mental processes. At the same time, the content of iron exerts more significant influences on the functional state of the CVS. It should be taken into account that the pattern of correlations found in our study is typical of a relatively specific sampling of the subjects (with a clearly pronounced deficiency of the above-mentioned elements in the organism) and can be dissimilar in the case of normal (and, especially, increased) contents of these metals.
