Abstract

The biological maturation status is an important factor that influences the talent identification process and development of sports talent. Several authors have shown that different morphological and functional aspects, such as body size, speed and strength have an individual rate of development during puberty, being highly dependent on the stage of sexual maturation. Given this influence of biological maturation on the talent identification process of young athletes, another phenomenon has been observed during this process, the Relative Age Effect (RAE). The RAE refers to the influence that the months of birth (chronological age) can result in learning and performance of a given task in young people. Therefore, following the assumption of the RAE, subjects born in the first quarters of the year could provide biological advantages (eg hormones), physical (eg height, weight, strength, speed, etc.), cognitive, psychological and learning about the same subject chronological age born in the last months of the year. These variations could affect performance, causing overestimation of the results observed during the talent identification process. Thus, the objective of this study is to analyze the RAE and biological maturation of young athletes selected for training programs in football long term. Therefore, in the first instance will be assessed youth soccer players participating in the talent selection process for entry into the sub-14 category of a football club, with national and international prominence. In the second phase of work will be collected the same variables in the group of young people selected to make the under-14 team of the club. The parameters are: month of birth, level of sexual maturity, testosterone and cortisol, body composition, overall strength (grip) and parameters of playing performance. (AU)
