Subjects: The purpose of the research is to reveal the individual-typological peculiarities of the reactivity of student`s capillary blood flow and to trace the change of the indicators of the blood microcirculation during the test with the bated breath. The experimental research has included the study of the functional state of the tissue blood flow by means of laser Doppler flowmetry (LDF). It has allowed assessing the condition of the blood flow and detecting the features of the changes of the microcirculation during the with bated breath. The obtained results have shown that the high-amplitude of LDF with the expressed vasomotor` waves has predominated in many students mainly. It has been revealed that the different level of the reactivity during the test with the with bated breath has been due to the individual-typological peculiarities of the blood microcirculation. The different levels of the reactivity de�pend on the vascular tone. Therefore
smaller meaning of the decrease of the blood flow during the bated breath in the examined students with the hypoemic type of the microcirculation is due to the increased initial tone of the capillaries. In the examined students with the hyperemic type of the microcirculation
in contrast
smaller size of the decrease of the blood flow with the bated breath is associated with the decreased vascular tone. Thus
the reactivity of the capillary blood flow in the examined students for the reaction to the test with the bated breath has been characterized with the sufficient level of the sympathetic influences in the regulation of the tissue blood flow.
