Th present study was designed to examine 409 practically healthy men at the age of 50 to 79 years differing in terms of daily locomotor activities. They were divided into 4 groups each comprising subjects whose age differed within 10 years. Group 1 included former high-class athletes continuing physical exercises. Group 2 consisted of former high-class athletes practicing sedentary lifestyle. Group 3 contained subjects regularly doing health-improving physical exercises and group 4 those who had never been engaged in sports activities. The main parameters measured in all the subjects included the heart rate, arterial pressure, stroke volume, pulse pressure, minute blood volume, cardiac index, total peripheral vascular resistance, and mean dynamic arterial pressure. It was shown that both the routine regime of motor activity and its history in the preceding period have significant influence on hemodynamic characteristics in late ontogenesis. The high level of routine motor activity in the former high-class athletes enabled them to maintain for a long time good functional state of the cadiovascular system compared with the former athletes practicing sedentary lifestyle and the subjects who had never been engaged in sports activities. The former athletes practicing sedentary lifestyle developed the hypokinetic type of hemodynamics by the age of 60-69 years.
本研究旨在对409名年龄在50至79岁之间、日常运动活动情况不同的健康男性进行检查。他们被分为4组，每组受试者年龄相差不超过10岁。第1组包括仍在进行体育锻炼的前高级运动员。第2组由过着久坐不动生活方式的前高级运动员组成。第3组包含定期进行健身锻炼的受试者，第4组是从未参加过体育活动的人。所有受试者测量的主要参数包括心率、动脉血压、每搏输出量、脉压、分钟血容量、心脏指数、总外周血管阻力和平均动态动脉压。结果表明，运动活动的日常规律及其前期历史对个体发育后期的血液动力学特征有显著影响。与过着久坐不动生活方式的前运动员和从未参加过体育活动的受试者相比，前高级运动员的高水平日常运动活动使他们能够长时间保持心血管系统的良好功能状态。到60至69岁时，过着久坐不动生活方式的前运动员出现了低动力型血液动力学。
