Player activity profiles of match play provide valuable information for optimal athlete training prescriptions, competition strategies, and managing load and recovery and are currently lacking in elite Australian-league (A-League) soccer. The aims of the study were, therefore, to (a) determine match activity profiles for elite A-League soccer players and make match-half and positional comparisons and (b) examine the effect of situational factors including evolving match status (drawing, winning, or losing) and goals being scored and conceded on selected match activity profile variables. Global positioning system tracking devices were used to determine activity profiles of 19 elite male adult soccer players during 8 preseason matches (n = 95 files). Total distance, average speed, high-intensity running (HIR) distance, and very high-intensity running distance decreased from the first to the second half by 7.92, 9.47, 10.10, and 10.99%, respectively. Midfielders covered 11.69% more total distance, 28.08% more HIR distance, and had a 10.93% higher average speed than defenders (p ≤ 0.05; d = 1.90, 1.03, and 1.83, respectively). Attackers performed 27.50 and 30.24% less medium accelerations than defenders and midfielders, respectively (p < 0.01; d = 1.54, and 1.73). When the team was winning, average speed was 4.17% lower than when the team was drawing (p ≤ 0.05, d = 0.32). Scoring or conceding goals did not appear to affect HIR. This study adds to limited knowledge of match demands in elite A-League soccer. The match activity profiles provide descriptive benchmarks that could be used to make comparisons with other elite level soccer populations while also providing a framework for game-specific training prescription, competition strategy, and load management. The generalization that defenders experience a relatively lower match load may be questionable given their relatively high acceleration and deceleration demands.
比赛中的球员活动概况为制定最佳运动员训练计划、比赛策略以及管理负荷和恢复提供了有价值的信息，而目前澳大利亚精英联赛（A联赛）足球领域缺乏这方面的信息。因此，本研究的目的是：（a）确定澳大利亚精英A联赛足球运动员的比赛活动概况，并进行半场和位置比较；（b）研究包括比赛状态演变（平局、获胜或失利）以及进球和失球等情境因素对选定比赛活动概况变量的影响。使用全球定位系统跟踪设备来确定19名成年精英男性足球运动员在8场季前赛中的活动概况（n = 95份文件）。总距离、平均速度、高强度跑步（HIR）距离和极高强度跑步距离从上半场到下半场分别下降了7.92%、9.47%、10.10%和10.99%。中场球员的总距离比后卫多11.69%，HIR距离多28.08%，平均速度比后卫高10.93%（p≤0.05；效应量分别为1.90、1.03和1.83）。前锋的中等加速度分别比后卫和中场球员少27.50%和30.24%（p < 0.01；效应量分别为1.54和1.73）。当球队获胜时，平均速度比平局时低4.17%（p≤0.05，效应量为0.32）。进球或失球似乎不影响HIR。本研究增加了对澳大利亚精英A联赛足球比赛需求的有限认识。比赛活动概况提供了描述性基准，可用于与其他精英水平的足球群体进行比较，同时也为特定比赛的训练计划、比赛策略和负荷管理提供了框架。鉴于后卫相对较高的加速和减速需求，认为后卫比赛负荷相对较低的普遍观点可能存在疑问。
