Determining the correlation between hemodynamic parameters and running speed in middle distances students-runners through the dual model of blood circulation of lower limbs

Issues of simulation of blood filling and blood circulation of runners’ lower limbs are considered. The dual model of body links conductivity is proposed, taking into account the specific resistance of blood and tissue, as well as transections of vessels and body segments. It is shown, that the resistance changes, recorded during rheography, are inversely related to the square of sum of the transections of blood vessels and tissue of the investigated segment. Comparison of changes of anacrota amplitude with the modulation of competitive running speed, power of heart muscle operation with the running speed and with blood circulation of lower limbs links was carried out. Carried out clustering of athletes allows them to be divided into two groups of athletes and it is possible to provide the performance of individual training tasks, which are oriented in terms of volume and intensity for each group.
