During the COVID-19 pandemic, the temporary closure of physical activity and sports facilities, and the generalized cancellation or postponement of sports events have a massive impact on social and economic development. In this study, we explored the feasibility of using tracking data from a football match to assess interpersonal contact between individuals by calculating two measures of respiratory exposure. The dynamic tracking positioning of all players and referees during one international football match was analyzed. For each individual, two measures of respiratory exposure were calculated, based on the 2 m interpersonal distance recommendations for contact tracing for COVID-19 control. Overall, individuals spent a median of 0.12 mm:ss (IQR = 0.45 mm:ss) exposed to interpersonal contact of fewer than 2 m from others. The highest value of exposure was observed between two players of opposing teams (6.35 mm:ss). The results suggest that tracking data can be used to assess respiratory exposure to interpersonal contact in team sports, such as football. The measures of exposure calculated can be used to the prompt identification of high-risk contacts of COVID-19 cases during a match or a training session, but also the risk stratification of different sports and physical activities.
在 COVID-19 大流行期间，体育活动和设施的临时关闭，以及体育赛事的普遍取消或推迟，对社会和经济发展产生了巨大影响。在本研究中，我们探讨了使用足球比赛的追踪数据通过计算两种呼吸暴露措施来评估个体间人际接触的可行性。分析了一场国际足球比赛中所有球员和裁判员的动态跟踪定位。对于每个人，基于用于 COVID-19 控制接触追踪的 2 米人际距离建议，计算了两种呼吸暴露措施。总体而言，个体的中位数暴露时间为 0.12 毫米：秒（IQR = 0.45 毫米：秒），与他人的接触距离少于 2 米。暴露的最高值出现在两支对立球队的两名球员之间（6.35 毫米：秒）。结果表明，跟踪数据可用于评估团队运动（如足球）中的人际接触呼吸暴露。计算出的暴露措施可用于在比赛或训练期间及时识别 COVID-19 病例的高风险接触者，也可用于对不同运动和体育活动进行风险分层。
