Age changes of blood microcirculation in students and sportsmen under the influence of physical training

Age specifi c features of blood microcircula詛 on reac誛 vity in students and athletes (freestyle wrestling at the level of
candidates for a master of sports) are studied for 18 to 21 years under the infl uence of a dosed physical training. Signifi cant
diff erences in the values of the most parameters characterizing the microcircula萋 on of blood at rest were observed between
the 4 age groups under examina裻 on, both in students and athletes with diff erent levels of the microcircula萋 on index, and it
was shown that the contribu詻 on of ac詻 ve modula脫 ons of the blood fl ow to the forma裻 on of its profi le is more important.
Regular exercise changes the age dependence of the level of muscle 詻 ssue perfusion, as well as the amplitude of blood fl ow
fl uctua詻 ons in 裻 ssues. Essen裻 al diff erences in the eff ect of physical training on the eff ec譋 veness of microcircula譋 on in stu-
dents and athletes have been established, depending on the value of the microcircula誛 on index. The results indicate the need
to take into account the hierarchy of regulatory mechanisms in the selec荫 on of the intensity of physical training, as well as
the possibility of a targeted eff ect on respiratory-pulse modula講 on in the microvasculature and, consequently, on their ra譛 o,
by means of dosed physical training.
