Аннотация:The aim of this study was to assess the age-related features of the functioning of the microcirculation system using the LDF method. The estimation of parameters of microcirculation was performed in practically healthy persons of mature age in a one-stage study and in a prospective study in children aged 8 to 11 years. Stable indices of microcirculation were recorded at different stages of adulthood with maximal values in the middle of this age period. In the prospective study, significant changes in the functioning of the microcirculation system in the period from 9 to 10 years, indicating the beginning of the transition to the pubertal period, were noted. The revealed age-specific features of the functioning of the microcirculation system are due to the level of metabolic activity of the body.
