This study aimed to investigate how ecological constraints influence individual player skill demands in community-level junior Australian Football (AF). Footage from 68 junior AF games, incorporating 1874 unique players, were analysed for individual skill demands such as disposals, kicks, handballs, tackles, marks, and shots at goal per player per game. Multiple linear mixed effect models were created for each skill, using player as a random effect. The impact of age, relative area per player (RAPP), number of players on the team, quarters in midfield, and weather on skill demands was assessed in U9-U14 boys. Finally, the influence of sex on the same skills was explored in U11-U14 boys and girls. Younger players were found to have fewer disposals and handballs, but more tackles, per player than older players (all < 0.05). Further, more quarters in the midfield increased all skill demands (all < 0.001). Finally, girls had fewer disposals and marks, but more tackles, per player than boys (all < 0.05). Overall, age, sex, and position significantly impacted players' exposure to skills in junior AF. Game designers should consider methods to improve skill involvement and reduce tackling exposure early in the junior pathway, with further emphasis on the girls' game.
本研究旨在探讨生态约束如何影响社区层面青少年澳式足球（AF）中个体球员的技能需求。对 68 场青少年 AF 比赛的录像进行了分析，其中包括 1874 名独特的球员，分析了每个球员每场比赛的个人技能需求，如处理球、踢球、传球、铲球、接球和射门。为每个技能创建了多个线性混合效应模型，使用球员作为随机效应。在 U9-U14 年龄段的男孩中，评估了年龄、每名球员相对区域（RAPP）、每队球员人数、中场区域的比赛节数和天气对技能需求的影响。最后，在 U11-U14 年龄段的男孩和女孩中探讨了性别的影响。与年龄较大的球员相比，年龄较小的球员每场比赛的触球和传球次数更少，但铲球次数更多（均 < 0.05）。此外，中场比赛节数的增加增加了所有技能需求（均 < 0.001）。最后，与男孩相比，女孩每场比赛的触球和接球次数更少，但铲球次数更多（均 < 0.05）。总的来说，年龄、性别和位置对青少年 AF 中球员的技能接触有显著影响。游戏设计者应考虑在青少年阶段早期提高技能参与度和减少铲球暴露的方法，对女孩的比赛应给予更多关注。
