title: [Analysis of hemodynamics in late ontogenesis in subjects with different regimes of motor activity].
abstract: 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.
