Abstract

The aim of this study was to analyze the distribution date of birth soccer goalkeepers who competed in the Championship Mineiro Season Base Category 2013 were collected by the Mineira Football Federation (FMF) dates of birth of 108 goalkeepers recorded in the 54 teams that competed in the mineiro championship in infant classes (sub-15 years), youth (under-17 years) and Junior (under 20 years) in 2013. Data were grouped in general and divided by category and analyzed quartiles and six months of birth. For statistical analysis, we used the chisquare test of proportions (p <0.05), and specifically in the case of comparing the quartiles were carried out multiple comparisons paired resorting to the Bonferroni correction (p <0.0083). It can be seen from the results of the study, that goalkeepers who played the Mineiro Football Championships Season 2013 of child and youth category were influenced by the relative age effect. There were no athletes in the junior class differences in the period from birth to indicate the effect of relative age.
