Given the dearth of research available on the elite women's Australian football (AFLW) competition, this study aimed to observe the position-specific peak movement demands of AFLW players and assess whether any seasonal changes have occurred in movement- or performance-based metrics over the initial three years of competition.
Observational longitudinal design.
Data were collected on one team across the initial three seasons of the AFLW competition. Global position system units were used to obtain the movement demands while performance metrics were obtained from an external statistical provider. Peak movement demands were determined using a rolling period analysis of 1-10 min durations. Mixed models were used to assess the influence of season and position on movement- and performance-based metrics.
Peak period high speed running (HSR, >14.4 km/h), but not total distance (TD), differed between playing positions, with midfielders covering the greatest peak period movements (p < 0.01). No seasonal changes were observed for peak periods of TD or HSR for any positions. Various mean running movements observed seasonal changes and positional differences (p < 0.01), albeit with small effect sizes. No performance-based metric differed by position. Seasonal changes were observed for handballs and uncontested possessions only (p < 0.01), with trivial effect sizes.
The small differences in on-field movement patterns and performance characteristics of AFLW players observed across seasons and between positional groups gives confidence that practitioners can continue to prescribe whole team rather than position-specific movement and technical training. External factors such as modification to competition structure and rules, or a change in team focus, may mask developments in this competition and warrants continued investigation.
鉴于针对澳大利亚女子足球联赛(AFLW)精英女性的研究甚少,本研究旨在观察 AFLW 球员的特定位置的最高运动需求,并评估在比赛的最初三年中,运动或表现相关指标是否发生了任何季节性变化。
观察性纵向设计。
在 AFLW 比赛的最初三个赛季中,对一个团队进行了数据收集。使用全球定位系统(GPS)单元获取运动需求,同时从外部统计提供商获取性能指标。使用 1-10 分钟的滚动周期分析来确定最高运动需求。混合模型用于评估季节和位置对运动和表现相关指标的影响。
中场球员的最高运动期高速跑动(HSR,>14.4km/h),而非总跑动距离(TD),在不同的比赛位置之间存在差异(p<0.01)。任何位置的 TD 或 HSR 的最高运动期都没有观察到季节性变化。观察到各种平均跑动动作的季节性变化和位置差异(p<0.01),尽管效果大小较小。没有表现相关指标因位置而异。仅观察到手球和非争抢控球有季节性变化(p<0.01),效果大小微不足道。
在整个赛季和不同位置组别中,AFLW 球员在场上的运动模式和表现特征方面的差异很小,这让从业者有信心可以继续规定整个团队而非特定位置的运动和技术训练。外部因素,如比赛结构和规则的修改,或团队重点的变化,可能会掩盖比赛中的发展,需要进一步调查。
