Player match statistics in junior Australian football (AF) are not well documented, and contributors to success are poorly understood. A clearer understanding of the relationships between fitness and skill in younger players participating at the foundation level of the performance pathway in AF has implications for the development of coaching priorities (eg, physical or technical).
To investigate the relationships between indices of fitness (speed, power, and endurance) and skill (coach rating) on player performance (disposals and effective disposals) in junior AF.
Junior male AF players (N = 156, 10-15 y old) were recruited from 12 teams of a single amateur recreational AF club located in metropolitan Victoria. All players were tested for fitness (20-m sprint, vertical jump, 20-m shuttle run) and rated by their coach on a 6-point Likert scale for skill (within a team in comparison with their teammates). Player performance was assessed during a single match in which disposals and their effectiveness were coded from a video recording.
Coach rating of skill displayed the strongest correlations and, combined with 20-m shuttle test, showed a good ability to predict the number of both disposals and effective disposals. None of the skill or fitness attributes adequately explained the percentage of effective disposals. The influence of team did not meaningfully contribute to the performance of any of the models.
Skill development should be considered a high priority by coaches in junior AF.
澳大利亚青少年足球（AF）比赛中球员的统计数据记录不完善，对比赛成功的影响因素了解不足。更清楚地了解参与AF表现路径基础阶段的年轻球员身体素质与技能之间的关系，对确定教练工作重点（如体能或技术）的发展具有重要意义。
研究青少年AF中身体素质指标（速度、力量和耐力）与技能（教练评分）对球员表现（传球和有效传球）的关系。
从位于维多利亚州首府的一个业余娱乐性AF俱乐部的12支球队中招募了青少年男性AF球员（N = 156，10 - 15岁）。对所有球员进行身体素质测试（20米短跑、垂直跳跃、20米穿梭跑），并由教练根据6点李克特量表对其技能进行评分（与队友相比在球队内部）。在一场比赛中评估球员表现，通过视频记录对传球及其有效性进行编码。
教练对技能的评分显示出最强的相关性，并且与20米穿梭跑测试相结合，对传球和有效传球的数量都具有良好的预测能力。没有任何一项技能或身体素质指标能够充分解释有效传球的百分比。球队的影响对任何模型的表现都没有显著贡献。
在青少年AF中，教练应将技能发展视为高度优先事项。
