Effects of Masks on Cardiopulmunary Exercise Capacity

Gerard P. emails as a follow up to my post, Strawman Attack on Mask Warnings :
Came across this recent study today on my twitter feed, relevant to your post on masks:
From the study:
Due to the SARS-CoV2 pandemic, medical face masks are widely recommended for a large number of individuals and long durations. The effect of wearing a surgical and a FFP2/N95 face mask on cardiopulmonary exercise capacity has not been systematically reported....
Ventilation, cardiopulmonary exercise capacity and comfort are reduced by surgical masks and highly impaired by FFP2/N95 face masks in healthy individuals. These data are important for recommendations on wearing face masks at work or during physical exercise.


  1. Bullish for health professionals either way

  2. Anyone with two brain cells to rub together knows this instinctively. We need to figure out how to stop it

    1. I just had an idea. Could someone sue an employer or government to require health screening for mask wearers? I read recently that OSHA requires health screening for mask wearing environments to verify you’re healthy enough to wear a mask. Don’t know if that’s true. But if it is, then the more expensive it gets for them the better.
