Face masks are promoted for preventing spread of viruses; however, wearing a mask during exercise might increase CO rebreathing, decrease arterial oxygenation, and decrease exercise performance. A systematic review and meta-analysis was conducted on the impact of wearing a mask during exercise. Data sources included SPORTDiscus, PubMed, and Medline. Eligibility criteria included all study designs comparing surgical, N95, or cloth masks to a no mask condition during any type of exercise where exercise performance and/or physiological parameters were evaluated. Healthy and clinical participants were included. Mean differences (MD) or standardized mean differences (SMD) with 95% confidence intervals were calculated and pooled effects assessed. Twenty-two studies involving 1573 participants (620 females, 953 males) were included. Surgical, or N95 masks did not impact exercise performance (SMD -0.05 [-0.16, 0.07] and -0.16 [-0.54, 0.22], respectively) but increased ratings of perceived exertion (SMD 0.33 [0.09, 0.58] and 0.61 [0.23, 0.99]) and dyspnea (SMD 0.6 [0.3, 0.9] for all masks). End-tidal CO (MD 3.3 [1.0, 5.6] and 3.7 [3.0, 4.4] mm Hg), and heart rate (MD 2 [0,4] beats/min with N95 masks) slightly increased. Face masks can be worn during exercise with no influences on performance and minimal impacts on physiological variables. PROSPERO registration: CRD42020224988.

口罩被宣传为预防病毒传播的手段；然而，在运动时佩戴口罩可能会导致 CO 重吸入增加、动脉血氧饱和度降低以及运动表现下降。我们对佩戴口罩运动对运动表现和生理参数的影响进行了系统评价和荟萃分析。数据来源包括 SPORTDiscus、PubMed 和 Medline。纳入标准为所有研究设计，比较了手术口罩、N95 口罩或布口罩与不戴口罩在任何类型运动时的差异，评估运动表现和/或生理参数。纳入健康和临床参与者。计算并汇总了平均值差异（MD）或标准化平均值差异（SMD）及其 95%置信区间，并评估了合并效应。共纳入 22 项研究，涉及 1573 名参与者（620 名女性，953 名男性）。手术口罩或 N95 口罩对运动表现没有影响（SMD-0.05[-0.16, 0.07]和-0.16[-0.54, 0.22]），但增加了感知用力程度（SMD 0.33[0.09, 0.58]和 0.61[0.23, 0.99]）和呼吸困难（所有口罩的 SMD 0.6[0.3, 0.9]）。呼气末 CO（MD 3.3[1.0, 5.6]和 3.7[3.0, 4.4]mmHg）和心率（N95 口罩时增加 2[0,4]次/分钟）略有增加。口罩可以在运动时佩戴，对运动表现没有影响，对生理变量的影响最小。PROSPERO 注册号：CRD42020224988。
