Chronological heredity (environmental) analysis, food, blood group, important variables for the selection of athletes on various sports events

The realization of this article was imposed by the need to react concretely on the issue of correlation relationships between heredity, nutrition, blood group, and the selection of athletes on various sports events, requirements imposed to coaches of the national sports teams and not only. In this sense, this article tries to remind the importance of overcoming obstacles in determining those who are predisposed to certain physical activities through modern methods of selection, namely considering heredity, nutrition, blood group. The support of this correlation model has a high degree of precision in terms of physical abilities, as it allows the application of this approach in the specific context and, last but not least, a signal that these things should be treated more seriously and responsibly by all actors involved in conducting/practicing performance sports, regarding the problems and barriers to achieving the objections put before the physical culture and sports specialist (coaches of national sports teams).
