Abstract：
Indoor air quality is a critical factor influencing athletic performance, particularly in professional sports settings, yet its impact remains underexplored. This study utilizes a panel dataset from 2516 Chinese Basketball Association (CBA) matches across 20 cities in China between 2014 and 2019. We integrate daily air pollution metrics with player efficiency ratings (PER) to investigate the effects of air quality on individual performance. We find that a 10% increase in the air quality index (AQI) corresponds to a 1.4223 decrease in PER, indicating a strong negative effect of poor air quality on player productivity. Different pollutants have varying effects, with some exacerbating the decline in both overall performance and precision in tasks. Notably, older players and international players exhibit greater resilience to air pollution. These insights contribute to the development of a comprehensive index for assessing work efficiency under varying air quality conditions and suggest targeted strategies to mitigate the negative impacts of air pollution in competitive athletic settings.
摘要：
室内空气质量是影响运动成绩的关键因素,特别是在专业运动环境中，然而，其影响仍未得到充分探索。这项研究利用了2014年至2019年间中国20个城市的2516场中国篮球协会（CBA）比赛的面板数据集。我们将每日空气污染指标与玩家效率等级（PER）相结合，以研究空气质量对个人表现的影响。我们发现，空气质量指数（AQI）增加10％对应于PER减少1.4223，表明空气质量差对球员生产力有很强的负面影响。不同的污染物有不同的影响，有些加剧了任务整体性能和精度的下降。值得注意的是,年长的球员和国际球员对空气污染表现出更大的抵御能力。这些见解有助于制定综合指数，以评估不同空气质量条件下的工作效率，并提出有针对性的策略，以减轻竞技运动环境中空气污染的负面影响。
