This study sought to longitudinally and retrospectively determine the relationship between professional career attainment and the development of anthropometric and physical qualities in junior Australian footballers. Eighty adolescent male Australian footballers from a single state academy previously selected onto an under 16 s talent development squad were classified by career attainment (professional team selection; n = 17 and non-selected; n = 63). Physical and anthropometric tests were conducted at the end of preseason during participation in under 16 and under 18 competitions. Tests included standing height, mass, stationary countermovement jumps, dynamic vertical jumps, 20-m sprints, agility and 20 m multistage fitness test. Both groups significantly improved all performance measures between the under 16 and under 18 levels. Athletes selected onto a professional team possessed significantly quicker 20-m sprint outcomes than non-selected athletes at both under 16 and under 18 levels, highlighting the importance of this physical capacity within talent development programmes. Binary logistic regression was unable to predict an effect of any measures on career attainment. An inability of the binary logistic regression to identify qualities predictive of long-term career success likely highlights limitations associated with utilising unidimensional models of assessment in talent identification practices. As such, development coaches and sport scientists should be aware that while physical capacities play a role in career attainment outcomes, other factors, such as tactical understanding and technical skill are also likely to be impactful.

身体和人体测量学特征的纵向发展是否与澳大利亚青少年足球运动员的职业生涯成就有关？

本研究旨在纵向和回顾性地确定职业生涯成就与澳大利亚青少年足球运动员的人体测量学和身体素质发展之间的关系。来自单个州学院的 80 名青少年男性澳大利亚足球运动员之前被选入 16 岁以下人才发展队，按照职业成就进行分类（职业球队选择；n = 17 和未选择；n = 63）。在参加 16 岁以下和 18 岁以下的比赛期间，在季前赛结束时进行了体格和人体测量测试。测试包括站立高度、质量、静止反向运动跳跃、动态垂直跳跃、20 米冲刺、敏捷性和 20 米多阶段体能测试。两组均显着提高了 16 岁以下和 18 岁以下水平之间的所有绩效指标。入选专业团队的运动员在 16 岁以下和 18 岁以下级别的 20 米短跑成绩上都比未入选的运动员快得多，这凸显了这种身体能力在人才培养计划中的重要性。二元逻辑回归无法预测任何措施对职业成就的影响。二元逻辑回归无法识别可预测长期职业成功的品质，这可能突出了在人才识别实践中使用单维评估模型的局限性。因此，发展教练和体育科学家应该意识到，虽然身体能力在职业成就中发挥作用，但其他因素，如战术理解和技术技能也可能会产生影响。
