Objective. Analysis of reasons behind usage, potentials and informativity of molecular-genetic technologies in sport.
Methods. Analysis of data of scientific and scientific-methodical literature, sports press, Internet.
Results. Different directions of sports genetics have been described. Several results obtained during molecular-genetic testing of the members of national teams of Belarus specialized in different sports events, have been presented.
Conclusion. Different directions of sports genetics are necessary to provide the athlete with the conditions for complete realization of his genetic potential. Therefore, each athlete should have genetic passport with indication of gene variants necessary to achieve high performances in selected sports event, the levels of their expression at rest and under loads as well as genes of pathology risk.
