The peculiarities of microcirculation in adolescents and subjects of preadult age

Gas diffusion and transcapillary exchange take place in the microvasculature. Therefore, the evaluation of skin blood flow regulation and its regulatory mechanisms at different development periods is of great importance. The research was conducted with the use of laser Doppler flowmetry (LDF). In the groups of adolescents of 13-16 years (52 subjects) and preadult people aged 17-20 years (41 subjects) skin microcirculation and its regulatory mechanisms were evaluated. It was found that in teenage and preadult age (in both sexes) the parameters of microcirculation and characteristics of the regulatory mechanisms of the microcirculation change not only due to age-related processes, but also because of the appearance of sexual differences at the end of the period of puberty.
