“…The similar anthropometric and physiological characteristics among BQ were in agreement with the absence of RAE in the present study. This relationship has been examined previously in soccer, where some studies supported an association between BQ and these characteristics, i.e., “early born” showed superior characteristics than “late born” (Pedretti and Seabra, 2015; Altimari et al, 2018), whereas other studies did not observe differences (De Oliveira Matta et al, 2015; Junior et al, 2015; Lovell et al, 2015; Skorski et al, 2016; Peña-González et al, 2018). An explanation of the similar anthropometric and physiological characteristics among BQ might be the role of maturation as a covariate (Lovell et al, 2015; Peña-González et al, 2018).…”

The relative age effect (RAE) on human performance has been well studied in many sports, especially in soccer; however, little information has been available about the prevalence of RAE in volleyball, and its role on anthropometric and physiological characteristics. The aim of the present study was to examine (a) the prevalence of RAE in selected (i.e., to be considered for the national team) and non-selected youth female volleyball players, and (b) the relationship of birth quarter (BQ) with anthropometric and physiological characteristics. Selected (n = 72, age 13.3 ± 0.7 years, weight 62.0 ± 7.2 kg, height 1.72 ± 0.06 m) and non-selected female volleyball players (n = 53, age 13.9 ± 1.1 years, weight 56.4 ± 7.3 kg, height 1.66 ± 0.06 m) performed a series of anthropometric and physiological tests. Twenty-six selected participants were born in the first quarter of the year, 19 in the second, 14 in the third, and 13 in the forth. The corresponding frequency by BQ in non-selected participants was 12, 12, 17, and 12. No association was observed between the number of participants and their frequency by BQ neither in the selected (χ2 = 2.79, p = 0.425) nor in the non-selected group (χ2 = 0.64, p = 0.886). Anthropometric and physiological characteristics did not vary by BQ (p > 0.05). The absence of RAE in female volleyball players and the similarities of anthropometric and physiological characteristics among BQ might be due to technical-tactical character of this sport. These findings would be of great practical value for coaches and fitness trainers working with young volleyball players.

The present study aimed to investigate the influence of months of birth on anthropometry, body composition, biological maturation, and motor performance in young Brazilian soccer players. Young Brazilian soccer players from the Under-13 (n = 50; 13.6 ± 0.3 years), Under-15 (n = 50; 15.5 ± 0.4 years), and Under-17 categories (n = 46; 17.7 ± 0.3 years) took part in this study. Athletes were divided according to chronological age, 1st tertile (January to April); 2nd tertile (May to August); and 3rd tertile (September to December). Anthropometry, body composition, biological maturation, and motor performance variables were evaluated for all participants. There were no differences between the U-13, U-15, and U-17 categories regarding birth tertiles (p > 0.05). Differences between the ages and birth tertiles were observed for the stature, body mass, and lean body mass (p < 0.05). Moreover, differences were found in maturational status between the ages and birth tertiles (p < 0.05). In general, U-13 players showed lower values compared to U-15 and U-17 players in tests of motor performance. In addition, there was a difference in motor performance between the birth tertiles only for RSA variables. The months of birth influenced the stature, body mass, lean body mass, and repeated sprint ability in the U-13 and U-15 categories. Thus, care should be taken during the process of talent selection, as many young players could be underestimated due to their date of birth.

Purpose. this study investigated the occurrence of relative age effect (RAE) in Brazilian elite soccer athletes depending on age categories, playing position, and competitive level. Methods. Data from 2660 male elite soccer athletes who participated in the 2019 Brazilian soccer championships were analysed. to determine RAE, the players were divided by their quarter of birth: Q1 (January-March), Q2 (April-June), Q3 (July-September), and Q4 (October-December). Data were obtained from the Brazilian Soccer Confederation (CBF) official website, and from each club's website when no information was available at the CBF website. Were included the athletes who participated in the 2019 Brazilian soccer championships in series A and B. Data were organized in accordance with age categories (under-20 or senior), playing position (forwards, midfielders, defenders, and goalkeepers), and competitive level (Series A or B).Results. An overrepresentation of soccer players born in the first quarter of the year was found when compared with the other quarters, whereas players born in the last quarter of the year were underrepresented, regardless of the age category and competitive level. Regarding playing position, an overrepresentation of soccer players born in the first quarter of the year was found for all playing positions in both age categories, except for the goalkeepers in the senior category. Conclusions. Our results showed a prevalence of RAE in U-20 and senior age categories in elite Brazilian soccer athletes, in both competitive levels, and for all playing positions, except for goalkeepers in the senior category.
