Objective: Aim of the work was to determine the peculiarities of rheographic parameters of the tibia in volleyball players of the general group and individual somatotypes.
Patients And Methods: Materials and Methods: A comprehensive examination of 108 highly skilled volleyball players and 130 practically healthy girls aged between 16 and 20 years who did not play sports was conducted. The rheovasographic parameters of the tibia were determined using tetrapolar reocardiography on a computer diagnostic complex with the assessment of amplitude, time, and indicators of the ratio of amplitude and time rheovasographic parameters.

Background: Quantitative assessment of hemodynamic parameters is an important element of ophthalmic diagnostics especially in early detection of myopia, glaucoma, diabetic retinopathy. The assessment of hemodynamic changes is essential in evaluating of the efficiency of treatment. Objective: Our aim was to determine the adequate of eye hemodynamics assessment using reoophtalmography in patients with various clinical refractions.

The device uses an algorithm of automatic recording and processing rheosignals, which has been developed on 20-year worldwide experience in applying rheography. Specific volumetric and velocity parameters, as well as total amplitude-time parameters of rheosignals and their ratios, which virtually satisfy all users are identified in the procedures for examining hemodynamics in the heart, extremity, head, liver and lung.

It is found that stress causes more significant disturbance of inotropic function in old rats as compared with adult animals. This disorder occurs earlier in old rats.

The work describes a method of using a home tetrapolar two-channel rheograph RPG-2-02 for a one-step registration of differential rheogram (DRG) of the chest and neck-head. The stroke volume of the heart and the systolic blood volume in the cervical arteries were calculated by the corresponding DRG and the Kublicek formula. The clinical approbation of the method gave similar results of the capacitance blood flow with the literature data and with the rheographic method of determination of the cerebral blood flow.
