背景:口罩在COVID-19大流行期间被广泛使用,作为预防病毒感染风险的保护措施之一。一些证据表明,长时间使用面膜可能会不舒服,运动过程中会加剧不适。然而,运动期间戴口罩对情感/心理和运动表现反应的急性反应仍然是一个争论的话题。目的:对运动期间戴口罩对不同/不同训练状态的健康成年人的情感/心理和运动表现反应的急性影响进行系统评价和荟萃分析。方法:本综述(CRD42021249569)是根据Cochrane的建议进行的。以电子方式进行搜索(PubMed,WebofScience,Embase,SportDiscus,和PsychInfo)和预打印数据库(MedRxiv,SportRxiv,PsyArXiv,和预打印。组织)。对纳入研究的数据进行了综合,RoB-2工具用于评估研究的方法学质量。评估的结果是情感/心理(不适,压力和情感反应,疲劳,焦虑,呼吸困难,和感知的劳累)和运动表现的疲惫时间(TTE),最大功率输出(POMAX),和肌肉力量生产]参数。通过荟萃分析汇集了现有数据。结果:最初确定了4,587项研究,包括36项临床试验(所有交叉设计)。在所有研究中,共评估了749名(39%为女性)健康成年人。发现的面罩类型是服装(CM),外科(SM),FFP2/N95和呼气阀FFP2/N95,而最常见的练习是跑步机和自行车测力计增量测试,超越户外跑步,阻力练习和功能测试。运动期间戴口罩会导致整体不适增加(SMD:0.87;95%CI0.25-1.5;p=0.01;I2=0%),呼吸困难(SMD:0.40;95%CI0.09-0.71;p=0.01;I2=68%),和感知的劳累(SMD:0.38;95%CI0.18-0.58;p<0.001;I2=46%);TTE降低(SMD:-0.29;95%CI-0.10至-0.48;p<0.001;I2=0%);对POMAX和步行/跑步距离无影响(p>0.05)。结论:运动时戴口罩会增加不适感(效果大),呼吸困难(中度影响),和感知的劳累(小影响),并降低了TTE(小效果),对自行车测力计POMAX和步行和跑步功能测试中行驶的距离没有影响。然而,某些方面可能取决于面罩类型,如呼吸困难和感觉到的劳累。系统审查注册:[https://www。crd.约克。AC.uk/prospro/display_record.php?ID=CRD42021249569],标识符[CRD42021249569]。
Background: Face masks are widely used during the COVID-19 pandemic as one of the protective measures against the viral infection risk. Some evidence suggests that face mask prolonged use can be uncomfortable, and discomfort can be exacerbated during exercise. However, the acute responses of mask-wearing during exercise on affective/psychological and exercise performance responses is still a topic of debate. Purpose: To perform a systematic
review with meta-analysis of the acute effects of mask-wearing during exercise on affective/psychological and exercise performance responses in healthy adults of different/diverse training status. Methods: This
review (CRD42021249569) was performed according to Cochrane\'s recommendations, with searches performed in electronic (PubMed, Web of Science, Embase, SportDiscus, and PsychInfo) and pre-print databases (MedRxiv, SportRxiv, PsyArXiv, and Preprint.Org). Syntheses of included studies\' data were performed, and the RoB-2 tool was used to assess the studies\' methodological quality. Assessed outcomes were affective/psychological (discomfort, stress and affective responses, fatigue, anxiety, dyspnea, and perceived exertion) and exercise performance time-to-exhaustion (TTE), maximal power output (POMAX), and muscle force production] parameters. Available data were pooled through meta-analyses. Results: Initially 4,587 studies were identified, 36 clinical trials (all crossover designs) were included. A total of 749 (39% women) healthy adults were evaluated across all studies. The face mask types found were clothing (CM), surgical (SM), FFP2/N95, and exhalation valved FFP2/N95, while the most common exercises were treadmill and cycle ergometer incremental tests, beyond outdoor running, resistance exercises and functional tests. Mask-wearing during exercise lead to increased overall discomfort (SMD: 0.87; 95% CI 0.25-1.5; p = 0.01; I2 = 0%), dyspnea (SMD: 0.40; 95% CI 0.09-0.71; p = 0.01; I2 = 68%), and perceived exertion (SMD: 0.38; 95% CI 0.18-0.58; p < 0.001; I2 = 46%); decreases on the TTE (SMD: -0.29; 95% CI -0.10 to -0.48; p < 0.001; I2 = 0%); without effects on POMAX and walking/running distance traveled (p > 0.05). Conclusion: Face mask wearing during exercise increases discomfort (large effect), dyspnea (moderate effect), and perceived exertion (small effect), and reduces the TTE (small effect), without effects on cycle ergometer POMAX and distance traveled in walking and running functional tests. However, some aspects may be dependent on the face mask type, such as dyspnea and perceived exertion. Systematic
