In the U19 and U21 age categories, statistical significance has not been confirmed. As for the senior national team, statistically significant difference has been found in relation to players born in the last quarter of the year as opposed to players born in the first three months of the year (p≤0.01). Our results have shown that with the increasing age, the relative age effect fades and vanishes in full in the category of senior elite players. In the U-19 and U-21 age categories, statistical significance has not been confirmed. Based on this research results it may be recommended to use the advantage of relative age effect for the selection of players of the particular age category in the particular competition (such as e.g. the European Championship qualification, the European Championship final tournament qualification, or the World Cup qualification in the U-16, U-17, U-18 age categories).</p></abstract>
