The effects of wearing cloth masks and surgical masks were investigated on respiratory rate, heart rate, blood pressure, oxygen saturation and perceived exertion at rest and after performing a six-minute walk test (6MWT) in older adults. Forty older adults were recruited and randomized into six groups including wearing no mask, cloth masks and surgical masks, at rest and during the 6MWT. At rest, all subjects sat quietly wearing no mask, a cloth mask or a surgical mask. All subjects performed a 6MWT by walking as fast as possible without running while wearing no mask, a cloth mask or a surgical mask. Respiratory rate, heart rate, blood pressure, oxygen saturation and perceived exertion were assessed before and after the rest and the 6MWT. Results showed that cloth masks and surgical masks did not impact cardiorespiratory parameters at rest or after performing a 6MWT, while an increase in perceived exertion was apparent in the groups wearing surgical masks and cloth masks after performing the 6MWT (p < 0.01). Cloth masks and surgical masks did not have an impact on cardiorespiratory fitness at rest and after performing the 6MWT in older adults.
研究了在老年人静息状态以及进行六分钟步行试验（6MWT）后，佩戴布口罩和外科口罩对呼吸频率、心率、血压、血氧饱和度和主观用力感觉的影响。招募了40名老年人，并将他们随机分为六组，包括在静息状态和6MWT期间不戴口罩、戴布口罩和戴外科口罩。在静息状态下，所有受试者安静地坐着，不戴口罩、戴布口罩或戴外科口罩。所有受试者在不戴口罩、戴布口罩或戴外科口罩的情况下，尽可能快地行走（不跑步）进行6MWT。在静息状态和6MWT前后评估呼吸频率、心率、血压、血氧饱和度和主观用力感觉。结果显示，布口罩和外科口罩在静息状态或进行6MWT后对心肺参数没有影响，而在进行6MWT后，戴外科口罩和布口罩的组主观用力感觉明显增加（p<0.01）。布口罩和外科口罩在老年人静息状态和进行6MWT后对心肺适能没有影响。
