Face masks for exercising are a source of heated debate. Some people will say they are perfectly fine for workouts, others will claim they block air flow when fresh oxygen is needed the most (during exercising). Some will go as far as suggesting that face masks specifically designed for sports, such as the UA SPORTSMASK and the Asics Runners Face Cover, are detrimental to your performance because it blocks the free-flow of oxygen, needed for peak muscle performance. A new research says otherwise.

A study published on 3 November 2020 from the University of Saskatchewan is here to clear things up, at least a little bit. As reported by ScienceDaily, the study found that "exercise performance and blood and muscle oxygen levels are not affected for healthy individuals wearing a face mask during strenuous workouts."

This is good news for anyone wanting to exercise in gyms and/or would like to attend group classes both indoors and outdoors. Indoor classes might not be available in many countries at the moment but it's highly likely that when they will be, face coverings will be recommended as well as having to adhere to social distancing measures, of course.

Better still, the study didn't even measure the performance of people wearing highly breathable sports face masks. The 14-people strong testing group sported a three-layer cloth face mask, as recommended by Dr. Theresa Tam, Canada's Chief Public Health Officer. These are less suited for exercising than the aforementioned performance masks, which are more likely to cause even less discomfort during workouts.
The study involved 14 'physically active and healthy' men and women, "controlled for the effects of diet, previous physical activity, and sleep during the 24 hours prior to the test", according to ScienceDaily.
A;; 14 of the participants warmed-up on a stationary bike then the researchers gradually cranked up the resistance all the while requiring participants to maintain a certain pedal rate. Once they could not sustain the pedal rate the test was over.
"Usually a participant reaches exhaustion on this test in six to 12 minutes depending on their fitness level," said Chilibeck, a professor in the USask College of Kinesiology, who was a co-author of the study.
To make sure the results were statistically significant, participants did the test three times each, "once wearing a surgical face mask, once wearing a cloth face mask and once with no face mask." The research team looked at blood- and muscle oxygen levels throughout the test using non-invasive measurement tools to see if there were any difference in these.
The researchers concluded by saying "our findings are of importance because they indicate that people can wear face masks during intense exercise with no detrimental effects on performance and minimal impact on blood and muscle oxygenation."
Next time you hit the gym or go to a class, make sure you wear your mask.
