The individual differences in the autonomic support of intellectual activity, including simple and complex sensorimotor reactions, memorization and reproduction (on the screen of the monitor) of visual information, were studied. The rate of performing intellectual computer-aided tests is a relatively steady individual characteristic revealed in different(More)
The usefulness of individual salivary protein spectra as indicators of resistance to stress is discussed. Analyses of total saliva performed before and after exposure to model stress showed that individual psychological and autonomic reactions correlated with specific changes in the concentrations of certain salivary proteins. Therefore, such an analysis(More)
Changes in the power and coherence of α activity and heart rate variability (HRV) were studied in students with different performance levels in logical tasks. The students achieving high results in cognitive tests exhibited higher liability of α activity and HRV; the values and their ratios varied among the stages of intellectual activity. In these(More)
We have conducted theoretical foundation, experimental analysis and a pilot study of a new method of adaptation to hypoxia and hyperoxia in the prevention of hypoxic and stress-induced disorders and improving the body's tolerance to physical stress. It has been shown in the experimental part that a combination of physical exercise with adaptation to(More)
We compared cytokine profi le of rat serum and brain structures after immune status modulation by LPS (30 μg/kg intraperitoneally). The content of infl ammatory (IL-1α, IL-1β, IL-2, IL-6, IFN-γ, and TNF-α) and anti-infl ammatory (IL-4 and IL-10) cytokines in biological samples of animals was measured on days 1 and 7 after antigenic stimulation. LPS(More)
The basic somnological methodology, which is extensively used in the present time, focuses only on clinical practice. However, this approach is not appropriate for monitoring of physiological functions during natural sleep under home conditions. Our work was designed to develop a new information-and-equipment device for the reliable study of human(More)
AIM to investigate the possibility of a new method--interval hypo-hyperoxic training (IHHT)--in the correction of the individual components of metabolic syndrome. MATERIALS AND METHODS The study included 35 patients with metabolic syndrome (alimentary obesity 1-3rd stage [BMI over 30 kg/m2], violation of carbohydrate tolerance or diabetes mellitus type(More)
The dynamics of microvascular circulation and tissue oxygenation in response to the hypoxic test and the subsequent hyperoxia have been studied. The microcirculatory and tissue oxygenation parameters (laser Doppler flowmetry and optical tissue oximetry) were recorded in 30 apparently healthy young men during the hypoxic test (HT): breathing a gas mixture(More)
Heart rhythm variability characteristics were studied in volunteers with different stability of the results upon switching from one type of intellectual activity to another. Individuals with stable results differed from those with worse accuracy of information reproduction by high initial CV, total power of heart rhythm variability and power of VLF, LF, and(More)
Physiological mechanisms of muscle activity during cyclic physical exercises of various intensity, including individual maximum exercise intensity, have been studied in 30 athletes. The system quantization of behavior showed that the spectral components of heart rate variability during attainment of individual maximum exercise intensity by athletes change(More)
