Influence of fitness, nature of physical loads in the activation of vascular endothelium athletes

Analyses of functional state of the vascular endo-thelium in a 44 sportsmen and in 45 healthy subjects are conducted. Athletes have been studied in terms of the various stages of the training process, depending on the condition of fitness and the nature of the physical activity. Markers of activation of vascular endothe-lium were within the physiological norm, though, and depended on the level of physical preparation of athletes, but have not violated the function of endothelial cells, regulating hemostasis, vascular tone. At the low level of fitness of the adaptation processes in the endo-thelium of vessels athletes are at the stage of their formation. The athletes with a high level of fitness they are fully adapted to the load and external influences.
