Wearing face masks is recommended for the prevention of contracting or exposing others to cardiorespiratory infections, such as COVID-19. Controversy exists on whether wearing face masks during vigorous exercise affects performance. We used a randomized, counterbalanced cross-over design to evaluate the effects of wearing a surgical mask, a cloth mask, or no mask in 14 participants (7 men and 7 women; 28.2 ± 8.7 y) during a cycle ergometry test to exhaustion. Arterial oxygen saturation (pulse oximetry) and tissue oxygenation index (indicator of hemoglobin saturation/desaturation) at vastus lateralis (near-infrared spectroscopy) were assessed throughout the exercise tests. Wearing face masks had no effect on performance (time to exhaustion (mean ± SD): no mask 622 ± 141 s, surgical mask 657 ± 158 s, cloth mask 637 ± 153 s ( = 0.20); peak power: no mask 234 ± 56 W, surgical mask 241 ± 57 W, cloth mask 241 ± 51 W ( = 0.49)). When expressed relative to peak exercise performance, no differences were evident between wearing or not wearing a mask for arterial oxygen saturation, tissue oxygenation index, rating of perceived exertion, or heart rate at any time during the exercise tests. Wearing a face mask during vigorous exercise had no discernable detrimental effect on blood or muscle oxygenation, and exercise performance in young, healthy participants (ClinicalTrials.gov, NCT04557605).
佩戴口罩有助于预防感染或暴露于呼吸道感染，如 COVID-19。在剧烈运动时佩戴口罩是否会影响表现，存在争议。我们使用随机、交叉平衡的设计，在 14 名参与者（7 名男性和 7 名女性；28.2±8.7 岁）中评估了在骑自行车至力竭测试中佩戴外科口罩、布口罩或不戴口罩的效果。在整个运动测试中，评估了股外侧皮氧饱和度（脉搏血氧饱和度）和组织氧合指数（血红蛋白饱和度/去饱和度的指标）。佩戴口罩对表现没有影响（力竭时间（平均值±标准差）：不戴口罩 622±141 s，外科口罩 657±158 s，布口罩 637±153 s（=0.20）；最大功率：不戴口罩 234±56 W，外科口罩 241±57 W，布口罩 241±51 W（=0.49））。当以相对于峰值运动表现的形式表达时，在运动测试的任何时候，佩戴或不佩戴口罩时，动脉氧饱和度、组织氧合指数、感知用力程度或心率都没有明显差异。在剧烈运动时佩戴口罩对年轻、健康参与者的血液或肌肉氧合以及运动表现没有明显的不利影响（ClinicalTrials.gov，NCT04557605）。
