The peculiarities of the circulatory functions were examined in sailors following nautical voyages of varying duration and directly on board during a 6-month cruise. Over 1200 persons were subjected to the examination. The overall morbidity was analyzed in a contingent of about 6000 persons. The whole material was statistically processed. The sailors were found to develop hypotensive reactions during the voyage that persisted following its termination. Cruises lasting over 2-3 months cause a significant tension of the adaptation mechanisms in the sailors, thus favouring the formation of persistent hypotensive states, inadequate reactions of the arterial pressure and heart rate, ECG changes that reflect the impairment of the functional state of the myocardium, etc. A lack of adaptation to cruises exceeding 2-3 months was established. The functional state of the cardiovascular system of sailors is considered to be one of the leading criteria for substantiating physiologically permissible duration of cruises.
对不同航行时长的海员进行了循环功能特点的检查，且在一次为期6个月的巡航期间直接在船上进行了检查。超过1200人接受了检查。对约6000人的总体发病率进行了分析。对全部资料进行了统计学处理。结果发现，海员在航行期间会出现低血压反应，航行结束后这种反应仍会持续。持续2至3个月以上的巡航会使海员的适应机制出现显著紧张，从而有利于形成持续性低血压状态、动脉血压和心率的不适当反应、反映心肌功能状态受损的心电图变化等。证实了对超过2至3个月的巡航缺乏适应性。海员心血管系统的功能状态被认为是确定生理上允许的巡航时长的主要标准之一。
