Resumo: | The relative age effect on sports has already been proven in several modalities and countries, in which athletes born in the initial months of each year have a competitive advantage in physical and psychological maturation compared to those born in the final months. This phenomenon occurs due to mistakes in the decision making of coaches and managers during the selection and promotion of the most talented athletes. However, there are indications that there may be a reverse effect of relative age, where the athletes born at the end of the year reach the adult category with higher technical quality, higher sports performance and higher market value than athletes born earlier in the year. This study analyzes the existence of the reverse relative age effect, based on market value and sports performance in a sample of Brazilian professional soccer athletes from the clubs of the Brazilian Championship 2015 ??? First Division. The data were collected in the database www.transfermarkt.pt and were analyzed by parametric linear regression and non-parametric chi-square test. The results indicate that the reverse relative age effect was demonstrated in relation to sports performance, but not in relation to market value. This study has the potential to contribute to the conceptual understanding of the phenomenon and to support better decisions in a management environment perspective of coaches and managers. Focusing on the Brazilian context, as an empirical context, contributes to the line of research on these phenomena in the field of sports management in the Brazilian academy and the training of new athletes. |

Este fen??meno ocorre devido aos erros na tomada de decis??o de treinadores e dirigentes durante a sele????o e promo????o dos atletas mais talentosos. No entanto, h?? ind??cios que pode haver um efeito reverso da idade relativa, em que os atletas nascidos no final do ano chegam ?? categoria adulta com maior qualidade t??cnica, maior desempenho esportivo e maior valor de mercado que os atletas nascidos no in??cio do ano. Este estudo analisa a exist??ncia do efeito reverso da idade relativa, com base no valor de mercado e no desempenho esportivo numa amostra de atletas brasileiros profissionais de futebol dos clubes do Campeonato Brasileiro 2015 ??? S??rie A. Os dados foram coletados na base de dados www.transfermarkt.pt e foram analisados pelo teste param??trico de regress??o linear e pelo teste n??o param??trico qui-quadrado. Os resultados indicam que o efeito reverso da idade relativa foi comprovado em rela????o ao desempenho esportivo, mas n??o em rela????o ao valor de mercado. Este estudo tem potencial para contribuir na compreens??o conceitual do fen??meno e de apoiar melhores decis??es numa perspectiva de foro gerencial dos treinadores e gestores. Ao focar o contexto brasileiro, como contexto emp??rico, contribui-se para a linha de pesquisa sobre estes fen??menos no campo da gest??o de esportes na academia brasileira e da forma????o de novos atletas.Submitted by Nadir Basilio (nadirsb@uninove.br) on 2017-04-18T14:38:27Z No. of bitstreams: 1 Luiz Antonio de Oliveira Ramos Filho.pdf: 569702 bytes, checksum: 63c6814d4aae8118f420c70f566ad50c (MD5)Made available in DSpace on 2017-04-18T14:38:27Z (GMT).

The relative age effect on sports has already been proven in several modalities and countries, in which athletes born in the initial months of each year have a competitive advantage in physical and psychological maturation compared to those born in the final months. This phenomenon occurs due to mistakes in the decision making of coaches and managers during the selection and promotion of the most talented athletes. However, there are indications that there may be a reverse effect of relative age, where the athletes born at the end of the year reach the adult category with higher technical quality, higher sports performance and higher market value than athletes born earlier in the year. This study analyzes the existence of the reverse relative age effect, based on market value and sports performance in a sample of Brazilian professional soccer athletes from the clubs of the Brazilian Championship 2015 ??? First Division. The data were collected in the database www.transfermarkt.pt and were analyzed by parametric linear regression and non-parametric chi-square test. The results indicate that the reverse relative age effect was demonstrated in relation to sports performance, but not in relation to market value. This study has the potential to contribute to the conceptual understanding of the phenomenon and to support better decisions in a management environment perspective of coaches and managers. Focusing on the Brazilian context, as an empirical context, contributes to the line of research on these phenomena in the field of sports management in the Brazilian academy and the training of new athletes. |
