Acceleration and deceleration are important given football is an intermittent sport with constant changes in velocity and direction. It is unclear, however, if the accelerations and decelerations performed by players differ between competition levels. The aim of the present study was to compare the acceleration, deceleration, and high-speed running profiles of players during international and domestic matches and to determine if differences were apparent across playing positions (defenders, midfielders, and attackers). GPS data from 21 Australian women's domestic football league matches over 2 seasons (2016-2018) and 15 Australian women's international matches (2017-2018) were collected and analyzed. Movement pattern data was collected using VX Sport and GPSports 10 Hz GPS receivers. Variables analyzed included: total distance, distance covered high-speed running (16-20 km·h) distance covered sprinting (> 20 km·h) and time spent accelerating and decelerating in four predetermined bands (1-2 m·s, 2-3 m·s, 3-4 m·s, and > 4 m·s). Results revealed that players competing in international matches covered significantly greater total distances, greater high-speed running distances and greater sprinting distances as well as spending a greater duration accelerating in band 4 compared to players in domestic competitions ( < 0.05). Players competing in international matches spent significantly less duration decelerating in bands 2 and 3, compared to players in domestic competitions. International defenders and midfielders recorded significantly higher total distances and high-speed running distance compared to players in domestic matches. Our findings suggest that preparing players for international-level competition should include progressive exposure to high-speed running and sprinting distances, as well as high magnitude accelerations. Furthermore, the higher running speeds experienced by players during international matches appears to be a result of less time spent decelerating. The optimal deceleration necessary for specific situations appears important and emphasizes the need for specific deceleration training. The increased effort of high-intensity activity that is required for players competing in international matches affects defenders and midfielders to the greatest degree. Gradual exposure to the increased running demands for midfielders and defenders competing in international matches is needed to improve performance and reduce the potential risk of injury.
鉴于足球是一项速度和方向不断变化的间歇性运动，加速和减速非常重要。然而，尚不清楚不同比赛水平的球员所进行的加速和减速是否存在差异。本研究的目的是比较国际比赛和国内比赛中球员的加速、减速和高速奔跑概况，并确定不同场上位置（后卫、中场球员和前锋）之间是否存在明显差异。收集并分析了来自两个赛季（2016 - 2018年）21场澳大利亚女子国内足球联赛比赛以及15场澳大利亚女子国际比赛（2017 - 2018年）的GPS数据。使用VX Sport和GPSports 10 Hz GPS接收器收集运动模式数据。分析的变量包括：总距离、高速奔跑（16 - 20公里/小时）覆盖的距离、冲刺（> 20公里/小时）覆盖的距离以及在四个预定区间（1 - 2米/秒、2 - 3米/秒、3 - 4米/秒和> 4米/秒）内加速和减速所花费的时间。结果显示，与国内比赛的球员相比，参加国际比赛的球员总距离、高速奔跑距离和冲刺距离显著更长，并且在区间4内加速的持续时间更长（P < 0.05）。与国内比赛的球员相比，参加国际比赛的球员在区间2和区间3内减速的持续时间显著更短。国际比赛中的后卫和中场球员记录的总距离和高速奔跑距离明显高于国内比赛的球员。我们的研究结果表明，让球员为国际水平比赛做准备应包括逐步增加高速奔跑和冲刺距离以及高强度加速的训练。此外，球员在国际比赛中经历的较高奔跑速度似乎是减速时间较少的结果。特定情况下所需的最佳减速似乎很重要，并强调了进行特定减速训练的必要性。参加国际比赛的球员所需的高强度活动增加的努力对后卫和中场球员影响最大。需要让参加国际比赛的中场球员和后卫逐渐适应增加的奔跑需求，以提高表现并降低受伤的潜在风险。
