PHYSIOLOGICAL AND BIOCHEMICAL PARAMETERS OF NORMOBARIC HYPOXIA STRESS IN HUMANS

The aim of the study is to examine dynamics sympathoadrenal and adrenocortical components acute normobaric hypoxia stress their correlation with some physiological biochemical parameters characterizing energy metabolism in humans.
 Materials methods. Fourteen trial subjects were exposed 40-minute while breathing nitrogen-oxygen mixture containing 9 % oxygen. At 5th, 10th, 20th, 40th minutes hypoxia, blood was taken from cubital vein for further analysis. authors determined a number parameters, such as pulse rate; pressure; oxygen consumption; rheographic index cerebral flow. We also evaluated epinephrine, norepinephrine, cortisol, lactate glucose levels at time sampling. estimated increase control points compared baseline, well various indicators.
 Results. A significant epinephrine (max. min 20), norepinephrine 10) 40) found under baseline parameters. consumption flow established 40). longer subject more degree conjugation response, flow, (lactate, glucose) was.
 Conclusion. obtained facts prove heterochrony human body response hypoxia. With development, impact adrenergic component on mobilizing glycolytic processes increases.
