Key result
Physical loads and training activities in young swimmers were associated with a significant increment in the concentration of endothelial function regulators.
Why the study?
The influence of physical loads on endothelial function and its regulatory mechanisms in young athletes of varying skill levels was not fully characterized.
Do physical loads and sports skill levels affect serum markers of endothelial function in young swimmers?
Observational
Do physical loads and sports skill levels affect serum markers of endothelial function in young swimmers?
Intense physical exercise in young athletes is associated with increased serum markers of endothelial function, suggesting active vascular adaptation to physical loads.

Supports vascular adaptation in young swimmers without practice change; hypothesis-generating for longitudinal trials on training effects.
Recent studies indicate to the special importance of endothelial function (EF) in processes of the regulation of blood circulation. There are presented data on the influence of physical loads on changes in EF on the basis of analysis of the changes of serum content of angiogenin, vascular endothelial growth factor, fibroblast growth factor, matrix metalloproteinase-9 and tissue inhibitor of MMP, thrombospondin and endothelin in young swimmers of various sports skill levels. During training activities and with gain in sports skill levels in young athletes there was found that a significant increment of the concentration of mentioned regulators may be a response to intense exercises indicating to active participation of endothelial vasculature of the growing body in a physiological mechanisms of adaptation to physical loads in children.

Bershova et al. (2019) conducted an observational in Healthy young athletes. Physical loads and training activities was evaluated on Changes in serum content of angiogenin, vascular endothelial growth factor, fibroblast growth factor, matrix metalloproteinase-9, tissue inhibitor of MMP, thrombospondin, and endothelin. Physical loads and training activities in young swimmers were associated with a significant increment in the concentration of endothelial function regulators.
