Public health officials have suggested the use of masks to limit the spread of the COVID-19 virus. Our results suggest wearing a mask during exercise will have no impact on performance.

- Wearing a reusable cloth facemask or a disposable mask has no detrimental effect on exercise performance
- In a healthy, active population, neither cloth nor surgical masks impact blood or muscle oxygenation during exercise, nor did they affect ratings of perceived exertion
- Public health officials have suggested the use of masks to limit the spread of the COVID-19 virus. Our results suggest wearing a mask during exercise will have no impact on performance
- The wearing of facemasks may be a low-cost way of decreasing transmission of the COVID-19 virus
- There are concerns around wearing facemasks during exercise due to the potential rebreathing of carbon dioxide or increased resistance to inspiration and respiration, increasing the work of breathing
- 14 active individuals (7 males, 7 females) performed a progressive cycle ergometer exercise test to exhaustion on three separate days: Once while wearing a 3-layer cloth face mask, once while wearing a disposable surgical face mask, and once with no mask. The order of these conditions was randomized with at least 48 h separating conditions.
- Participants rested quietly for 5 minutes and then performed a 5-min warm-up at a self-selected resistance, which was recorded and used on subsequent visits. The test started at a power output from 35 to 100 W depending on the fitness level and was increased 35 W every 2 min until exhaustion.
- Heart rate, arterial oxygenation, and rating of perceived exertion (modified Borg scale) were measured every 30 seconds during the exercise test. Tissue oxygenation of the quadriceps (measured using near-infrared spectroscopy) was measured continuously and analyzed as 20-second averages.
- Time to exhaustion and peak power output were recorded following completion of each test.
What the researchers found
- Time to exhaustion during the exercise test and peak power output were not different for face mask compared to no face mask conditions
- No differences were observed in physiological variables between masked and non-masked conditions at any time during the exercise test.
- There were no differences between men and women in their ability to tolerate vigorous exercise while wearing a face mask.
- Exercise performance and physiological variables during an incremental cycle ergometer test were not affected by wearing either a disposable surgical face mask or a reusable cloth face mask
- Our findings indicate that people can wear face masks during intense exercise with no detrimental effects on performance and minimal impact on blood and muscle oxygenation
