ABSTRACT: The present article considers the influence of environmental conditions on the body tympanum of girls and the adaptive reactions of peripheral hemodynamics to the physical activity. We carried out the evaluation of the environmental situation in the places of the permanent residence of girls, measured the anthropometric indices, calculated the trohanter index and defined a constitutional type of the age-related evolution of the body. The study of tibia hemodynamics was carried out by using rheovasography at rest, after a single dosage of physical activity in the amount of 50% of the individual PWC₁₇₀ and in the recovery period. The study revealed that the pollution of the environment by chemical and radionuclide factors on the territory of the Republic of Mordovia is characterized as uneven. In polluted areas disevolutive and pathological types of the body tympanum is normally formed. An influence of the constitutional type of the age-related evolution of the body on the tibia blood flow was observed during physical activity (statistically significant inverse correlation of the trohanter index and the rheographic index). The authors identified the following constitutional types of hemodynamic responses to physical activity: average values of​​ the trohanter index (norm-evolutive type of the body tympanum) were characterized by adequate response of tibia hemodynamic to physical stress; girls living in adverse environmental conditions, if the trohanter index was deviated from its average values, had a constitutional violation of peripheral hemodynamics. The identified hemodynamic features should be taken into account when planning physical activity in a business environment, as well as in training conditions of athletes.
