Annotation Research problem. It has been shown earlier that the physical training can reduce the resistance of the person to the vertical position of body. Simplifying the revealed regularities, it is possible to summarize that "highly trained athlete can run perfectly, but can't stand". It is known that at initially reduced orthostatic stability the growth of orthostatic tolerance is observed under the influence of the moderate training loadings. The task has been set: to study the hemodynamics indicators before and after the load tests, and not only in sitting position, but also in the standing one. Work hypothesis: orthostatic stability tends to decrease after long-term load among the insufficiently trained people, but to a lesser extent among the athletes that is connected with more adequate regulation of the peripheral blood-groove at orthoclase.
