[Types of circulation in people with varying physical training]

In 125 young healthy males the cardiac output was estimated by means of tetrapolar rheoplethysmography. The marked differences were found in indices of central hemodynamics and specific peripheral resistance between the groups of sportsmen and non-sportsmen in spite of almost equal systemic arterial pressure in both groups. These differences are greatly due to the types of hemodynamics and in lesser degree--to the level of physical training and trend of sporting training.
