The organization and implementation of the methodology for the simultaneous research of central hemodynamics and hemodynamics in the lower limbs and in visceral organs – the liver and spleen, which have a special blood supply, was carried out in laboratory conditions, with dosed physical exertion. To conduct the research, the participation of a team of researchers (one manager and 6 researchers) who work with the subject (located on a bicycle ergometer) is necessary. The main device for studying hemodynamics is a rheograph: computer diagnostic complex «ReoCom XAI-Medika», 8-channel. The research type «Rheography of the lower limbs + thoracic abduction» was applied. The manufacturer of the device does not provide the type of study «Rheography of the liver + spleen», but we carried it out, since the design of the device and its software allow the user to create new types of rheography studies. And the study of the effect of physical exertion on the hemodynamics of the named organs is expedient given the fact that they have the function of a blood depot, which is included in the redistribution of the volume of circulating blood during physical exertion. Approbation of the method, which was carried out with the involvement of 22 volunteers, turned out to be successful and effective. We obtained data that simultaneously showed the state of central and peripheral hemodynamics during dosed physical exertion in laboratory conditions.
