The study investigated the impact of empty stadium matches and rule changes due to COVID-19 on the match performance in the Chinese Super League (CSL), including both technical and physical performance. Technical indicators considered were passing accuracy, number of passes, and number of challenges, while physical indicators included total distance, average speed, number of sprints, and sprint distance. Statistical significance was accepted at p < 0.001. The results showed that empty stadium matches led to a significant decrease in passing accuracy, while the number of passes and challenges increased. The changes in rules indicated a significant decline in players' total running distance, average speed, number of sprints, and sprint distance compared to pre-pandemic levels, although the average distance of high-speed runs increased. The pandemic had a more pronounced impact on players' physical performance. Coaches can use this information to adjust training plans for players during special periods to mitigate adverse effects on physical performance.
该研究调查了因新冠疫情导致的空场比赛和规则变化对中国足球超级联赛（中超）比赛表现的影响，包括技术表现和身体表现。所考虑的技术指标有传球准确率、传球次数和对抗次数，而身体指标包括总距离、平均速度、冲刺次数和冲刺距离。当p < 0.001时，认为具有统计学显著性。结果表明，空场比赛导致传球准确率显著下降，而传球次数和对抗次数增加。规则变化表明，与疫情前水平相比，球员的总跑动距离、平均速度、冲刺次数和冲刺距离显著下降，尽管高速奔跑的平均距离有所增加。疫情对球员的身体表现影响更为显著。教练可以利用这些信息在特殊时期调整球员的训练计划，以减轻对身体表现的不利影响。
