Клинико-функциональная характеристика адаптации сердечно-сосудистой системы моряков при автономном плавании

Purpose . Assessment of functional state of circulatory system in seafarers at different stages independent cruise. Materials and methods . Retrospective analysis of the results of the study of three groups of 180 seafarers on the third, fifth and sixth months of cruise was conducted. The obtained results were subjected to statistical processing according to the rules of variation statistics. Results and its discussion . Functional state of circulatory system in seafarers depends on the kind of military professional activity. Thus, among the staff officers, the number of prehypertensive states is increasing, and for the personnel of surface ships a slightly greater physical working capacity is noted in comparison with divers. At the same time, an increase in the temperature of the skin of the lower extremities was typical for divers, that is definitely important for the control and early prevention of overheating. At the same time, the most noticeable decrease in working capacity is observed in the command staff, while the indicator was quantitatively correlated with the results of daily monitoring of blood pressure and ECG. In addition, it was revealed that the process of adaptation of the body’s regulatory systems reaches its maximum by the end of the third month of cruise and is determined by an increase in endurance and a decrease in morbidity among seafarers.
