The aim of this study was to characterise the acceleration and sprint profiles of elite football match play in one Norwegian elite football team (Rosenborg FC). Fifteen professional players in five playing positions took part in the study (n = 101 observations). Player movement was recorded during every domestic home game of one full season (n = 15) by an automatic tracking system based on microwave technology. Each player performed 91 ± 21 accelerations per match, with a lower number in the second compared with the first half (47 ± 12 vs. 44 ± 12). Players in lateral positions accelerated more often compared to players in central positions (98.3 ± 20.5 vs. 85.3 ± 19.5, p < 0.05). Average sprint distance was 213 ± 111 m distributed between 16.6 ± 7.9 sprints, with no differences between first (106 ± 60 m, 8.2 ± 4.2 sprints) and second halves (107 ± 72 m, 8.3 ± 4.8 sprints). Players in lateral positions sprinted longer distances (287 ± 211 m vs. 160 ± 76 m, p < 0.05) and tended to sprint more often (21.6 ± 7.8 vs. 13.0 ± 5.7, p = 0.064) compared to players in central positions. We found more walking and less of the more intense activities during the last third of the season compared to the first. The main finding in this study was that Norwegian elite players had substantially less number of accelerations and fewer but longer sprints than previous studies reported for higher-ranked leagues. Also, less high-intensity activity was found towards the end of the season. Ultimately, these data provide useful information for the fitness coach (1) in planning of position-specific football training and (2) to avoid the decline in high-intensity activities the last third of the competitive season.
本研究的目的是描绘一支挪威精英足球队（罗森博格足球俱乐部）在精英足球比赛中的加速和冲刺概况。五个场上位置的15名职业球员参与了这项研究（共101次观察）。通过基于微波技术的自动跟踪系统，记录了一个完整赛季中每一场国内主场比赛（共15场）期间球员的移动情况。每名球员每场比赛进行91±21次加速，下半场的加速次数比上半场少（47±12次对44±12次）。与中场位置的球员相比，边锋位置的球员加速更频繁（98.3±20.5次对85.3±19.5次，p<0.05）。平均冲刺距离为213±111米，分布在16.6±7.9次冲刺中，上下半场之间没有差异（上半场106±60米，8.2±4.2次冲刺；下半场107±72米，8.3±4.8次冲刺）。与中场位置的球员相比，边锋位置的球员冲刺距离更长（287±211米对160±76米，p<0.05），且冲刺频率更高（21.6±7.8次对13.0±5.7次，p=0.064）。我们发现，与赛季初期相比，赛季最后三分之一阶段球员的步行更多，高强度活动更少。本研究的主要发现是，挪威精英球员的加速次数大幅少于先前针对更高级别联赛报道的次数，冲刺次数更少但距离更长。此外，在赛季末发现高强度活动减少。最终，这些数据为体能教练提供了有用信息：（1）用于制定特定位置的足球训练计划；（2）避免在赛季最后三分之一阶段高强度活动的减少。
