In the last thirty years research on relative age effects (RAEs) has exploded in numbers. However, the stability and variability of these effects have hardly been investigated. The three aims of this retrospective study were first to investigate the stability and variability of RAEs over 17 years, second to compare these effects for young female and male athletes, and third to compare these effects between selected and non-selected athletes relative to variability estimates from 17 years prior to assess possible changes in athlete development trends. For this study, birth dates were provided for all participants of the talent selection camps by the German Handball Federation from 2008 to 2024. Results show that first while some variability was observed, the effects remained stable. Second, there are only small differences between sexes in general, although these increased with selection. And thirdly, that selections create stronger effects for male athletes, but not for female ones. Taken together, this study provides an interesting picture of the variability and stability of relative age effects over 17 years.
在过去三十年中，关于相对年龄效应（RAEs）的研究数量激增。然而，这些效应的稳定性和变异性几乎未得到研究。这项回顾性研究的三个目的，一是调查17年间相对年龄效应的稳定性和变异性，二是比较年轻男女运动员的这些效应，三是相对于17年前的变异性估计，比较入选和未入选运动员之间的这些效应，以评估运动员发展趋势可能发生的变化。在本研究中，德国手球联合会提供了2008年至2024年人才选拔营所有参与者的出生日期。结果表明，第一，虽然观察到了一些变异性，但效应保持稳定。第二，总体而言，性别之间只有微小差异，不过这些差异随着选拔而增加。第三，选拔对男性运动员产生的效应更强，但对女性运动员则不然。综上所述，本研究呈现了一幅关于17年间相对年龄效应变异性和稳定性的有趣图景。
