[Physical adaptability of the cardiorespiratory complex in sailors of European North].

The authors assessed physiological adaptation in 26 divers and 54 submariners doing military service in the Arctic circle of the European North. There was a stable regulation of cardiac rhythm due to its vasomotor component in the divers and autonomic lability in the submariners, a worse reaction to orthostatic changes during functional tests in the divers than in the submariners. The orthostatic test-induced reduction in the total power of the cardiac rhythm variability spectrum in the submariners was referred by the authors to as the asthenic phenomena caused by the specificity of their service activities. The distinctive type of divers' respiration, which was characterized by lower velocity properties and ample possibilities during forced respiration, was detected.

[Adaptation of divers in the European North].

The article gives a value of physiological condition of plungers's organisme during the most unfavorable season of the year-- polar night--in condition of based planed readiness (n = 26). Data of researches concluded necessary parameters of anthropometry, homodynamic, respirator functions. Supplementary diagnostic base was made by methods from the program of express-control of functional conditions. The results of the searches gave an opportunity to esteem the examined group of service men as people with tight vegetal nervous system, high level of neurohumoral regularity, which common for the physically strong people. It confirms the effectiveness of existing system of choice of plungers. The authors offer to fix a system of physiological monitoring of the health of all the service men. The purpose of this action is an early revelation of donozoologial conditions.
