“…Data revealed that sample is predominantly composed of early-birth young people. Evidence partially confirms the study´s first hypothesis and agrees with several other analyses in the literature which show a high representation of players born within the first six months of the years, in basketball (Arrieta et al, 2016;Ibãnéz et al, 2018) and in other sports modalities (Leonardo, Lizana, Krahenbühl & Scaglia, 2018;Huertas et al, 2019;Jackson & Comber 2020).…”

“…In this context, the RAE has been extensively studied in different types of sports, such as ice hockey (Fumarco, Gibbs, Jarvis & Rossi, 2017), baseball (Katsumata, Omuro, Mitsukawa & Nakata, 2018), handball (Leonardo, Lizana, Krahenbühl & Scaglia, 2018;Wrang, Rossing, Diernaes, Hansan, Dalgaard-Hansen & Karbing, 2018), volleyball (Papadopoulou et al, 2019), soccer (Bezuglov, Nikolaidis, Khaitin, Usmanova, Luibushkina, Repetiuk & Knechtle, 2019;Bidaurrazaga-Letona, Badiola, Granados, Lekue, Amado & Gil;Huertas et al, 2019;Jackson and Comber, 2020), basketball (Ibãnéz, Mazo, Nascimento & García-Rubio 2018;Ribeiro Júnior, Lobão, Oliveira, Vianna & Werneck, 2020), athletics (Brustio, Kearney, Lupo, Ungureanu, Mulasso, Rainoldi & Boccia, 2019;Valero et al, 2020) and padel (Muñoz, González, Quintana-García & Peinado, 2021). The evidence found has revealed physical, maturational, and psychological differences between players born at the beginning of the year and players born at the end of the year.…”

The Relative Age Effect has been the subject of study by researchers who seek to understand sports performance. This study aimed to analyze the prevalence of relative age effect (RAE) in basketball players, verifying whether early-birth players and the features of the place they inserted affect probable recruitment for athletic teams. The sample was comprised 1,455 players within 9 and 19-year-old. Variables included birth semester, gender, sports category, number of recruitments, geographical region. Data were analyzed using descriptive statistics and binary logistic regression model. The results found that early-birth players had a better chance to be recruited for state athletic teams u13 than late-birth ones. Players u15 and u17 had similar chances. Further, u13 and u15 players linked to the northern region for Brazil and in cities with very high Human Development Index (HDI) and medium-sized cities had a better recruitment chance for state team. Results may be employed by coaches, recruiters and headhunters, since variables associated to RAE may affect the state team and players´ performance throughout the process of sports formation. Removing the influence of relative age-related differences is predicted to improve the accuracy of identifying skilled players. Resumen. El efecto de la edad relativa (RAE) ha sido objeto de estudio por parte de investigadores que buscan comprender el desempeño en el deporte. El presente estudio tuvo como objetivo analizar el predominio del efecto de la edad relativa (RAE) en jugadores de baloncesto, verificando si los jugadores de nacimiento temprano y las características del lugar donde estaban insertos inciden en el probable reclutamiento para equipos deportivos. La muestra estuvo compuesta por 1.455 jugadores de entre 9 y 19 años. Las variables incluyeron semestre de nacimiento, género, categoría deportiva, número de reclutamientos, región geográfica. Los datos fueron analizados mediante estadística descriptiva y modelo de regresión logística binaria. Los resultados encontrados demostraron que los jugadores de nacimiento temprano tenían mayores posibilidades de ser reclutados para equipos atléticos estatales sub13 que los de nacimiento tardío. Los jugadores sub15 y sub17 tuvieron oportunidades similares. Además, los jugadores sub13 y sub15 vinculados a la región norte de Brasil y en ciudades com alto Índice de Desarrollo Humano (IDH) y ciudades medianas, tuvieron mayores oportunidades de ser reclutados para el equipo estatal. Los resultados pueden ser empleados por entrenadores, reclutadores y cazatalentos, ya que las variables asociadas al RAE pueden afectar el desempeño del equipo estatal y de los jugadores a lo largo del proceso de formación deportiva. Se prevé que al eliminar la influencia de las diferencias relativas relacionadas con la edad mejorará la precisión en la identificación de jugadores habilidosos.

“…This seems to highlight the relevance of the players' experience for the team's final classification (González, 2004). Some studies, however, have indicated that both men and women players from Q1 (born in January-March) tend to play more games (Bjørndal et al, 2018) and more time per game (Leonardo et al, 2018) than those born in the subsequent trimesters. No relationship was found between RAE and the player's position or goals scored.…”

“…Another study analysed the relationship between the number of games played and the trimester of birth in an international sample of Norwegian players, finding that players born in Q1 (January-March of the senior year) played more games than those born in Q8 (October-December of the junior year) in the women's youth category (Bjørndal et al, 2018). Likewise, a study of Brazilian U13 male players found that those born in Q1 (January-March) played longer than those born in Q4 (October-December) (Leonardo, Lizana, Krahenbuhl, & Scaglia, 2018).…”

The objectives of this study were (i) to determine whether there is a relationship between the relative age effect (RAE) and the final classification of the teams, player's positions, number of goals scored, and shooting effectiveness, and (ii) to determine whether there are differences in the number of goals scored and shooting effectiveness depending on the final classification and player's positions. The study subjects were 380 players who took part in the 2018 Women's Youth World Handball Championship. The independent variables were the relative age effect and the number of goals and shooting effectiveness of each type of shot. The dependent variables were the player's position and the team's final classification. To investigate the relationship between the RAE and the team's final classification, player's position, goals scored, and shooting effectiveness, contingency tables were drawn up and subjected to a chi-squared test. The dependence of the differences in goals and shooting effectiveness on the team's final classification and the player's position was studied by means of an ANOVA with a Tukey post hoc test. For the sample overall, there was no RAE, only an association between the classification and the year of birth, with more players born in the senior year in the teams ranked from 1st to 8th place than in those classified from 9th to 24th place. The teams classified from 1st to 4th had more significant numbers of several variables. There were differences in goals and shooting effectiveness, depending on the player's position. KEY WORDS performance, game-related statistics, throwing, back, wing, pivot Handball can be considered an intermittent contact sport that intercalates actions of high intensity (sprints, jumps, shots, and blocks) with those of medium/low intensity (walking or jogging movements, passes).

Resumo. A pesquisa investigou por intermédio do levantamento dos atletas federados da ginástica artística brasileira que participaram de ao menos um dos dois campeonatos nacionais (n=620), se o tamanho da população (estratificada em cinco categorias) é um fator que influenciam no sucesso esportivo, utilizando para tanto regressão logística binaria. Por segundo, utilizando o teste de Kruskall-Wallis, classificando o ranking de atletas em quartis buscou identificar se a densidade populacional é um fator de influência para ter rendimento esportivo. Os resultados indicam que no Brasil, pertencer a cidades maiores (100001 até 500000 habitantes) faz com que atletas possuam 7,51 vezes (IC95%=6.30-8.96) mais chances de ter resultados esportivos de rendimento, com destaque para os homens em cidades com densidade populacional mais baixa em comparação com as mulheres, sendo um possibilidade explorar a influência das políticas públicas de icentivo ao esporte nestas cidades.Abstract. The survey investigated through the survey of federated athletes of Brazilian artistic gymnastics who participated in at least one of the two national championships (n = 620), whether the population size (stratified into five categories) is a factor that influence the sporting success, using binary logistic regression. Second, using the Kruskall-Wallis test, ranking the ranking of athletes in quartiles sought to identify whether population density is an influencing factor for sports performance. The results indicate that in Brazil, belonging to larger cities (100001 to 500000 inhabitants) makes athletes have 7.51 times (95% CI = 6.30-8.96) more chances to have sportive performance results, especially men in cities. with a lower population density compared to women, and it is possible to explore the influence of sport-promoting public policies in these cities.
