Background: T he purpose of this study was to identify the relative age effect (RAE) in European youth badminton through examining participation trends. Material and methods: T he birthdate distributions of 1909 badminton players (males = 994, females = 915) participating in the last three consecutive European U15, U17 and Junior (U19) Badminton Championships were analysed. Chi-square (χ²) goodness-of-fit tests were used to determine inter-quartile differences, and odds ratios (OR) and 95% confidence intervals were calculated in order to compare quartiles with each other. Results: Statistically significant over-representation of players born shortly after the cut-off date was determined. Regarding gender, RAE was more notable in males compared to females, and the strongest results were determined in U15 compared to the other age categories. Moreover, striking trends were determined in Q1–Q4 comparisons, particularly as players in Q1 were more than twice for females and thrice for males as likely to participate in the European Badminton Championships. Conclusions: F indings of this study confirm the presence of RAE in European youth badminton though decreasing its intensity with age. Certain precautions or different approaches should be taken into consideration to organize the age categories, such as biological markers, variations, rotations or age quota for equal opportunities.

“…The phenomenon of relative age effect (RAE) reflects the asymmetrical distribution of athletes based on their birth dates, relative to an arbitrary cutoff ( Lidor et al, 2021 ). Evidence indicates that RAE influences selection and talent identification in different team sports ( Rubajczyk and Rokita, 2020 ; Schorer et al, 2013 ) such as soccer ( Yagüe et al, 2020 ; Figueiredo et al, 2022 ; Szwarc et al, 2019 ), basketball ( Kalén et al, 2021 ), rugby ( Kelly et al, 2021 ), futsal ( Castro et al, 2022 ), handball ( de la Rubia et al, 2021 ; Peña-González et al, 2021 ), and volleyball ( Campos et al, 2020 ; Işın. and Melekoğlu 2020 ; Rubajczyk and Rokita, 2020 ; Safranyos et al, 2019; Solon Junior and Silva Neto, 2020 ), with older athletes having better chances of being selected by coaches and talent scouts compared to their younger peers within an age category ( Furley and Memmert, 2016 ).…”

Athletes born closer to an arbitrary cut-off date are more likely to reach an elite level in sport, which is supported by a phenomenon called the relative age effect (RAE). It is important to determine whether this phenomenon is present in a sport to minimize this selection bias. This study aimed to investigate the prevalence of RAE in elite volleyball athletes, considering the influence of gender, the playing position (Setter, Middle, Libero, Opposite, and Outside Hitter) and the performance level (attack points, aces, and block points). The sample comprised 203 male and 193 female athletes competing in the Superliga A in the 2020/2021 season, which was equivalent to all of the teams of the championship. The data collection was performed during May and June, 2021. Athletes were organized according to gender, the playing position, and performance in the Superliga. For performance variables, athletes were separated based on the median value (90.0), and classified as high- or low-performance. Chi-squared tests were performed to verify differences between birth date distributions in relation to the aforementioned variables. Results indicated overrepresentation of relatively older male athletes (Q1 = 35.96%; Q2 = 27.59%; Q3 = 19.21%; Q4 = 17.24%), especially in Middles, Opposites, and Outside Hitters, regardless of their performance level. Considering females, no differences were found. Our findings suggest that RAE operates differently for men and women in elite Brazilian volleyball. The characteristics of the games played by male and female elite athletes may lead to different talent selection processes, affecting the likelihood of RAE prevalence.

This study aimed to explore the relevance of the relative age effect (RAE), maturity status and anthropometry, and their influence on coaches’ assessment of players’ performance, analyzing both genders and different types of academies (elite vs. non-elite). The sample included 603 soccer players (385 male), from the under 12 (U12), under 14 (U14) and under 16 (U16) categories, belonging to elite and nonelite teams. Coaches’ assessment of players´ performance, chronological age, anthropometric characteristics, maturity offset (MO) and peak height velocity (PHV) were registered. Our results showed that RAE was present in both genders within the elite, but not in the nonelite academies. Early maturity players were overrepresented in the male elite, but not in the female academies. No relationship was found between RAE and anthropometry in male elite academies. Male elite players showed better anthropometric characteristics than nonelite players, while this pattern of results was not found for female players. The coaches´ assessment on players´ current performance was not influenced by the chronological age nor anthropometry, but it was linked to the PHV. Coaches from nonelite academies rated better in current assessment of performance the taller players. Our findings suggest that maturity status and RAE play an independent and important role in the talent selection process.
