但在运动量达到最大时戴口罩会使空气吸入量不足。我们都知道佩戴医用口罩会增加气流阻力。锻炼一定会导致呼吸更快更用力,所以运动期间佩戴口罩对气流会造成进一步的压力。
At low to moderate-intensity exercise, effort will feel slightly harder than normal with a mask, but you can still walk comfortably. The challenge appears to be more during heavy exercise (say, rugby or football) taking in air at rates of about 40-100 litres per minute.
进行中低强度锻炼时会感觉比平时戴口罩时呼吸更费力,但你走路时依旧很舒服。做剧烈运动(如橄榄球或足球)时问题就更严重了,每分钟吸入空气量约为40-100升。
When we do heavy exercise, our muscles produce lactic acid, which causes that burning sensation. It is then converted to carbon dioxide and exhaled. But what happens if the carbon dioxide is trapped by the mask? As you move from moderate to heavy exercise, you may be re-breathing carbon dioxide, which can reduce cognitive function and increase breathing rate.
做剧烈运动时,我们的肌肉产生乳酸,会有灼热的感觉,然后转化为二氧化碳呼出。但如果二氧化碳被口罩挡住了会怎样?随着你的运动强度从中度到剧烈,你可能会重新吸入二氧化碳,这会降低认知功能,增加呼吸频率。
There may also be less oxygen in the recycled air, which could imitate exercising at higher altitudes. So it is important we gain a better understanding of the limitations of heavy exercise with a face mask.
