“…Due to the more intensely competitive atmosphere of basketball, (which was also the case for the junior basketball players in this study), a similar situation has been observed in many studies of young athletes, for example, Diaz in his study of the relative age effect (RAE) in the U12 basketball championships in Spain, found that 83.4 per cent of the 2,268 players were born in the rst half of the year (41), and Arietta's study of the relationship between relative age and realistic performance among young relative age (RAE) study on the relationship between relative age and real-world performance among talented basketball players also found that U16, U18, and U20 European Championship athletes had a high percentage of rstyear rst-borns, especially among male athletes (42). and Delorme et al found that rst-year rst-borns were underrepresented among athletes who gave up on the sport in the 2005-2006 French Junior Basketball Championships and had a very high percentage and a clear competitive advantage for athletes born in the rst half of the year (43).…”

“…While there is currently no evidence con rming the presence of RAE in basketball in China, particularly during adolescence, analogous studies have been conducted in other countries. For instance, researchers examining the birth months of adolescent basketball players in the French ACB and Spanish basketball leagues (LEB1 and LEB2) observed that male athletes born in the rst quarter exhibited a higher prevalence of superior performance compared to those born in the fourth quarter (14). Additionally, a study on RAE in the German professional basketball league revealed its persistent existence as an inequality that could potentially impact athletes later in their careers (35).…”

“…The inception of the RAE investigation can be traced back to the eld of education, where Grondin (2) initially identi ed its presence among Canadian amateur, competitive, and professional volleyball and ice hockey players. Subsequently, a substantial body of literature has emerged delving into the impact of RAE in various sports, including football (10)(11)(12),basketball (13,14), volleyball (15) ice hockey(16) and rugby (17).…”

Background The relative age effect (RAE) has been a hot topic in the field of sport research, and although the phenomenon has been found in most sports in China, there is currently no literature on the RAE phenomenon in Chinese basketball, which has implications for explaining some of the phenomena in that sport. A large body of research suggests that RAE contributes significantly to the phenomena of brain drain and inequality in sport participation. The purpose of this study was to analyses whether RAE exists in Chinese youth men's basketball and whether RAE has an impact on the performance of athletes and teams, thus supporting the subsequent proposal of measures to balance the age effect.Methods This study analyzed the date of birth and performance rankings of all male athletes (n = 3926) who participated in the Chinese Youth Basketball Championships (U14, U15, and U17) from 2021–2023. The study divided the month of birth into quarters and semesters. Differences between actual observed and theoretical birth date distributions were statistically analyzed using the chi-square test, and subsequent calculations were made using the dominance ratio test.Results It was found that RAE was present in all three groups of Chinese youth male basketball players (p < 001). The percentages of athletes born in the first half of the year were 61.2% (U14), 59.9% (U15), and 59.0% (U17), and the percentages of athletes born in the first quarter were 38.6% (U14), 35.8% (U15), and 34.8% (U17).Conclusions As a result of RAE, U15 athletes born closer to the beginning of the year are likely to achieve better results, whereas athletes born closer to the end of the year are less likely to achieve athletic excellence.

“…Notably, the top-ranked teams displayed a notable trend of having more players born in the first half of the year. This suggests that U12 basketball teams might experience improved performance due to the RAE [ 41 ]. Contrastingly, other studies propose varying patterns of RAE in basketball.…”

Ballon d’Or is the most important individual award in football, and is a significant measure of excellence. From our knowledge, this is the first study that explored the relative age effect (RAE) throughout the history of the Ballon d’Or. A total of 1899 football players nominated for the award from the first edition in 1956 to the most recent edition (2023) were analyzed. To assess the RAE, the birthdate distributions were categorized into four trimesters. The comparison involved correcting for the uniform distribution using chi-square analysis, with Cramer’s V serving as a measure of effect size. Standardized residuals were computed to identify quarters that exhibited significant deviation from the expected values. Odds Ratio and 95% confidence intervals were used to identify discrepancies between trimesters. The results indicated a pronounced presence of an RAE at the global level. However, the longitudinal analysis revealed variations in the behavior of the RAE over time. In the initial decades, there is an overrepresentation of players born in the last months of the year. Subsequently, there is no discernible RAE. In the most recent decades, there has been a clear resurgence of RAE, with an overrepresentation of players born in the first quarters of the year.
