[THE CHARACTERISTIC OF SOMATOTYPE AND FUNCTIONAL STATE OF CIRCULATORY SYSTEM OF STUDENT YOUTH OF THE NORTHEAST OF RUSSIA].

The article considers results of single-step study in random sampling of female students of the M.K. Ammosov north-east federal university (n=456). The study was carried out to investigate somatotype and functional state of circulatory system. The standard technique was applied to measure height, body mass, chest circumference, level of arterial pressure and rate of heart beats. The type of somatotype was established using Pignet index. The tone of vegetative system was determined using Kérdö index. The adaptation potential of circulatory system was determined using functional changes index. The results of study established that in 61% of examined female students the type of constitution corresponds to normosthenic one. The percentage of persons with asthenic and hypersthenic type of constitution amounted to 27% and 12% correspondingly. The signs of increasing oftone ofsympathetic nervous system are observed in 89% of girls. The functional condition of circulatory system is evaluated as "tension of adaptation mechanisms" that is apparently related to period of adaptation to new conditions. The prolonged preservation of such states results in exhaustion offunctional resources of organism and can promote development of diseases. In conditions of impacting of unfavorable ecological factors the deconditionning disorders can significantly contribute to health disturbances and decreasing of life quality. To preserve youth's health during period of education the comprehensive strategy is to be implemented such components as dynamic monitoring of health, organization of adequate diet, explanation of necessity of observance of sleep and rest pattern, development of conditions for active aerobic physical exertion and activities on correction of risk factors of development of diseases are to be included.
