This study sought to determine the association of relative age and performance of young elite basketball players. The distribution of the birth dates, heights, positions, classification and performance of the male and female participants (n = 2395) of the U16, U18 and U20 European Basketball Championships were analysed. We found an over-representation of players born during the initial months of the year in all groups, with the relative age effect being more evident in players of the U16 and U18 groups, than of the U20 teams, particularly in male squads. Nevertheless, in the U20 championships, those teams that had the oldest players performed the best. In all championships, the oldest participants played more minutes. In addition, relatively older male players scored better in total points and in performance index rating when results were normalised to played time. This effect was not found for female players. Regarding playing position, different distributions of birth dates were observed due to each position’s physical requirements. Thus, basketball coaches and managers should keep these results in mind when they select players because if not, they might subject players who are born towards the end of the year to a negative selection bias. 相似文献

- A group of UK-based learned societies were anonymously interviewed to understand how trends are affecting their missions, strategies, and operations.
- The societies' missions focus on supporting academics and disseminating knowledge, with publishing being a means to achieve those goals rather than an end in itself.
- The responses were concerned about addressing open access (OA) but, particularly in the post-COVID-19 era, this was not necessarily their highest priority.
- The societies expressed reliance on larger corporate publishers on them to navigate the transition to OA publishing.
- The societies' focus is on evolving their missions to meet the changing needs of their academic communities, with issues around premises as a result of COVID-19 being more pressing than publishing industry changes.
- The societies face challenges in adapting to the shift to online and digital operations, particularly in regards to maintaining engagement with their members.
