The study investigates relative age effects (RAE) in German youth soccer (Youth Bundesliga A: January 2004 to December 2005 and B: January 2006 to December 2007; highest league in German youth soccer) and its persistence in third-division players. Data from the 2022-2023 season (120 teams, 3,174 players) were analyzed using chi-square tests. Significant RAE was found in the A-series ( < .001), B-series ( < .001), and third-division professionals ( < .001). Notably, RAE was prominent among younger players but less evident in older third-division players ( = .116), indicating a diminishing selection effect with age and professional tenure. Coaches and talent managers are advised to consider RAE and additional factors like player maturity in talent selection for more efficient talent management strategies, especially in youth academies.
该研究调查了德国青少年足球（青少年德甲A组：2004年1月至2005年12月；B组：2006年1月至2007年12月；德国青少年足球最高级别联赛）中的相对年龄效应（RAE）及其在丙级联赛球员中的持续性。使用卡方检验分析了2022 - 2023赛季的数据（120支球队，3174名球员）。在A组（<0.001）、B组（<0.001）和丙级联赛职业球员（<0.001）中发现了显著的RAE。值得注意的是，RAE在年轻球员中较为突出，但在年龄较大的丙级联赛球员中不太明显（=0.116），这表明随着年龄和职业年限的增加，选拔效应逐渐减弱。建议教练和人才经理在人才选拔中考虑RAE以及球员成熟度等其他因素，以制定更有效的人才管理策略，特别是在青训营中。
