There is limited research in talent identification in youth Australian Football (AF), especially the factors that underpin selection into higher-level development programs. Therefore, this study explored age-related differences in high-level youth AF players and investigated characteristics influencing selection into a high-level development program. Anthropometry (stature, sitting height, body mass), maturity (estimated age at peak height velocity), motor competence (Körperkoordinationstest für Kinder), fitness (change of direction speed, lower body power and upper body muscular endurance) and coach skill ratings (kicking, marking and handballing) of 277 state academy players (U13-U15) were assessed. MANOVAs identified significant age-related differences for anthropometry, fitness, and coach skill ratings. Furthermore, 90.9 and 90.0% of U15 selected and deselected players were classified correctly. Selected players were more mature, taller, heavier, more explosive, faster at changing directions, and had superior kick technique and marking results. These results demonstrate considerable age-group performance outcome differences, highlighting that high-level academies should aim to select or deselect after 15 years of age. Additionally, it appears earlier maturing players are favoured for selection into a high-level academy. While practitioners must consider the confounding effect of maturation, early maturing players may be favoured for their ability to withstand increasing demands in higher-level youth AF.
在澳大利亚青年足球(AF)的人才选拔方面,研究有限,尤其是选拔进入更高水平发展计划的基础因素。因此,本研究探讨了高水平青年 AF 运动员的年龄相关差异,并调查了影响进入高水平发展计划的特征。对 277 名州学院球员(U13-U15)的人体测量学(身高、坐高、体重)、成熟度(预计身高生长高峰期年龄)、运动能力(儿童身体协调测试)、体能(变向速度、下半身力量和上半身肌肉耐力)和教练技能评分(踢球、标记和手球)进行了评估。MANOVA 确定了人体测量学、体能和教练技能评分方面与年龄相关的显著差异。此外,90.9%和 90.0%的 U15 入选和落选球员被正确分类。入选球员更加成熟、更高、更重、更具爆发力、变向速度更快,并且具有更好的踢球技术和标记成绩。这些结果表明,不同年龄组的表现存在显著差异,这表明高水平学院应该在 15 岁后进行选拔或淘汰。此外,似乎更早成熟的球员更有希望被选入高水平学院。尽管从业者必须考虑成熟的混杂影响,但更早成熟的球员可能因其能够承受高水平青年 AF 中不断增加的需求而受到青睐。
