The primary goal of this study is to analyze anthropometric characteristics of young football players and to determine the presence of differences in morphology, based on their playing positions and birth quartiles. If such differences do exist, seek to offer scientifically based answers to questions about the importance of morphology in the selection process of young U-16 football players, taking into consideration the roles they carry out on the field and also, to acknowledge how much are morphological differences represented and evident in that youth category. In this study, 36 anthropometric variables were measured on a sample of 32 young football players from a high ranking Croatian football club between the age of 15 and 16 years old (age: 15,48±0,51 years, height: 179,31±6,57 cm., body mass: 68,44±6,69 kg). Entities were categorised into three groups according to their playing position: attackers, middlefielders and defenders. Furthermore, they were categorised into four quartiles according to their birthdate: 1.Quartile = January-March, 2.Quartile = April-June, 3.Quartile = July-September, 4.Quartile = October-December. The analyses of differences between the groups was performed using the univariate analysis of variance (ANOVA) with the degree of significance set at p ≤ 0.05. Significant differences between the groups were discovered in only a few morphological variables such as knee diameter, body mass and basal metabolism (BMR) in regards to playing position. When looking at birth quartiles, arm span and shoulder width were the only two variables with significant differences. These results provide us with scientifically based facts which can be implemented in the selection and training process of young football players in relation to their anthropometric characteristics.
