Face masks do not interfere with breathing during exercise, findings-ScienceDaily

A new study from the University of Saskatchewan (USask) shows that exercise performance and blood and muscle oxygen levels in healthy people wearing face masks during intense training are unaffected.

Does wearing a mask during strenuous exercise reduce oxygen uptake or increase carbon dioxide rebreathing, leading to a condition in which increased carbon dioxide replaces oxygen in the blood (hypercapnia)? The question has been raised.

However, a study published in a research journal on November 3 International Journal of Environmental Research and Public HealthNo evidence was found to support these concerns.

“Our findings are important because they show that you can wear a face mask during strenuous exercise with minimal impact on blood and muscle oxygenation without adversely affecting performance.” The researchers say.

“This is important when the fitness center opens during COVID-19. During strenuous exercise, vigorous breathing can further promote respiratory droplets, and COVID-19 clusters in crowded closed exercise facilities. Because there is a report of. “

This study evaluated the use of a three-layer cloth mask. This is the type recently recommended by Dr. Teresatam, Canada’s Chief Public Health Officer. “The results of using a single-layer cloth mask can vary,” the researchers say.

In this study of 14 physically active and healthy men and women, we managed the effects of diet, previous physical activity, and 24-hour sleep before the test.

“People wearing face masks during indoor exercise can make sessions safer and leave the gym open during COVID,” said research co-author Phil Chilibeck, a professor of exercise at the University of Saskatche. Says. “There is also the possibility of continuing sports, such as hockey, which seems to have a high COVID-19 infection rate.”

Participants had to do a quick warm-up on an exercise bike. In the exercise test, I gradually increased the strength of the bike while maintaining the required pedal speed. The test was over when they couldn’t maintain the pedal rate.

“Usually, participants will feel tired in 6-12 minutes on this test, depending on their fitness level,” says Chilibeck.

The team evaluated participants who tested three times each, once with a surgical face mask, once with a cloth mask, and once without a face mask. The team used non-invasive measurement tools to record participants’ blood and muscle oxygen levels throughout the test.

The study is timely, as Saskatchewan has issued a new public health order coming into force this week, mandating masks to curb the spread of COVID-19 in indoor public spaces in Regina, Saskatoon and Prince Albert. It states that.

The new state’s Mask Regulations stipulate that people exercising in gyms, ice rinks, or other recreational spaces are exempt, but Chilibeck is an area where breathing can be difficult due to particularly intense conditions. The exercise recommends wearing masks at these facilities to ensure safety.

The USask research team also included kinematics graduates Keely Shaw and John Ko, Scotty Butcher of the School of Rehabilitation Medicine, and Gordon Zello of the School of Pharmacy and Nutrition.
