In this study, we analyse the proximity between professional players during a soccer match. Specifically, we are concerned about the time a player remains at a distance to a rival that is closer than 2 m, which has a series of consequences, from the risk of contagion during a soccer match to the understanding of the tactical performance of players during the attacking/defensive phases. Departing from a dataset containing the Euclidean positions of all players during 60 matches of the Spanish national league (30 from and 30 from , respectively, the first and second divisions), we analysed 1,670 participations of elite soccer players. Our results show a high heterogeneity of both the player-player interaction time (from 0 to 14 min) and the aggregated time with all opponents (from <1 to 44 min). Furthermore, when the player position is taken into account, we observe that goalkeepers are the players with the lowest exposure (lower than 1 min), while forwards are the players with the highest values of the accumulated time (~21 min). In this regard, defender-forward interactions are the most frequent. To the best of our knowledge, this is the largest dataset describing the proximity between soccer players. Therefore, we believe these results may be crucial to the development of epidemiological models aiming the predict the risk of contagion between players and, furthermore, to understand better the statistics of all actions that involve proximity between players.
在本研究中，我们分析了足球比赛期间职业球员之间的接近程度。具体而言，我们关注一名球员与对手保持在2米以内距离的时间，这会产生一系列后果，从足球比赛期间的传染风险到对球员在进攻/防守阶段战术表现的理解。基于一个包含西班牙国家联赛60场比赛（分别来自第一和第二级别联赛各30场）中所有球员欧几里得位置的数据集，我们分析了1670名精英足球运动员的参赛情况。我们的结果显示，球员之间的互动时间（从0到14分钟）以及与所有对手的总互动时间（从小于1到44分钟）都存在高度异质性。此外，考虑球员位置时，我们发现守门员的暴露时间最短（低于1分钟），而前锋的累计时间值最高（约21分钟）。在这方面，后卫与前锋之间的互动最为频繁。据我们所知，这是描述足球运动员之间接近程度的最大数据集。因此，我们认为这些结果对于旨在预测球员之间传染风险的流行病学模型的发展可能至关重要，而且，能更好地理解所有涉及球员之间接近的行为的统计数据。
