The purpose of this study was to analyse the activity profile of players in a top-class team in the Italian national football league over the course of a season (n=388). The effect of playing position and the two halves on the number and duration of short, intense bursts of effort and recovery phases was studied. The main results show that midfielders cover significantly more distance than players in other positions (p<0.001). For midfielders, the number of displacements of 2-40 m and the number of sprints covering between 2 and 9 m and between 30 and 40 m are considerably greater than for other positions (p<0.05). The distances covered in the second half compared to the first half are significantly lower for all categories of run (p<0.05). In the second half, the distance covered at very high intensity is significantly lower (p<0.01), whilst the number of recovery times greater than 120 s increases significantly compared to the first half (p<0.01). This study provides data which could be used as a basis for the work of scientists as well as football professionals.
本研究的目的是分析一个顶级球队在意甲联赛一个赛季中的球员活动情况（n=388）。研究了比赛位置和上下半场对短时间、高强度冲刺的次数和恢复阶段持续时间的影响。主要结果表明，中场球员的跑动距离明显高于其他位置的球员（p<0.001）。对于中场球员来说，2-40 米的跑动次数和 2-9 米以及 30-40 米的冲刺次数都明显多于其他位置（p<0.05）。与上半赛季相比，所有类别的跑动距离在下半赛季都明显降低（p<0.05）。在下半赛季，高强度跑动的距离明显降低（p<0.01），而大于 120 秒的恢复时间次数明显增加（p<0.01）。本研究提供的数据可以作为科学家和足球专业人士工作的基础。
