Аннотация: Reserve body capabilities and human health state assessment at the early stages of genesis is an urgent problem not only in clinical practice, but also in the field of physical education and sports. Purpose: application of the technique of laser Doppler flowmetry in physical education classes for the study of blood micro-circulation in students with health abnormalities. Materials and methods. The experiment involved 117 students (boys n=53, girls n=64, aged 18.4 ±0.3 years), who had a special medical group for physical education according to the results of periodic medical examination. To assess the functional state of the micro-circulation system, a laser blood micro-circulation device «LAZMA-PF» was used. Testing was carried out in the middle of the school day, during the inter-session period, in a state of physiological rest. Registration of laser Doppler flowmetry (LDF) was performed from the skin of the index finger of the left hand, in a sitting position. The assessment of blood oxygen saturation (saturation, SPO2) was performed using a pulse oximeter. Results. When studying micro-circulation in students of different sexes, there is a relative weakening of arterial vascular tone and an increase in blood volume in arterioles in males, as well as a deeper modulation of blood flow in this category of students. At the same time, the coefficient of variation value shows an improvement in the state of micro-circulation in girls. This is realized in the mechanisms of ensuring vascular tone, where in girls there is an increase in the neurogenic and endothelial components of regulation, and in boys there is an increase in passive links in ensuring micro-circulation. In girls, there is an increase in blood oxygen saturation, as well as a higher rate of heart rate and systolic blood pressure. The studied parameters indicate an increase in tension in the cardiovascular system regulation in male students. Conclusions. The data obtained during the study of students' body micro-circulation can be used for dynamic monitoring of students' with disabilities health status, and, if necessary, to correct motor activity and the mode of educational and daily activities. Undoubtedly, conducting these research works is also useful when conducting stress tests, as well as when studying the dynamics of changes in the functional status of micro-circulation in different periods of the academic year.
