Masks do not impair lung function during exercise: study

New York: When a facial mask can feel uncomfortable, researchers say it does not significantly alter the actual function of breathing or the flow of oxygen and carbon dioxide when worn while exercising.
The physical obstruction caused by the masks raises concerns that they damage the cardiovascular system by making it difficult to breathe, altering the flow of inhaled oxygen and emitted carbon dioxide, and increasing dyspnea.
Dyspnea is a medical term that describes shortness of breath or difficulty breathing, especially during physical activity.
In a new study published in the American Thoracic Society’s journal Annals, the research team concluded that while feelings of discomfort may increase, there is little empirical evidence that wearing a face mask significantly impairs lung function. Decreases form, even when worn during heavy exercise.
The research states that “there may be a maximum effort perceived with the activity, but the effects of wearing a mask on the work of breathing on gases such as oxygen and CO2 in the blood or other physiological parameters are very small, which Too small to detect. ” Author Susan Hopkins from the University of California, San Diego in the United States.
The researchers came to the conclusion after reviewing all the well-known scientific literature that was published, which examined the effects of different facial masks and different breathing apparatus on physical and mental reactions to physical activity.
These studies looked at multiple factors, such as respiratory function (energy spent on breathing and breathing), arterial blood gases, effect on muscle blood flow and fatigue, cardiac function, and blood in the brain. Flow
For healthy people, the effects of wearing a mask on these body marks were minimal, regardless of the type of mask worn or the degree of exercise.
The authors also say that age did not play a significant role in adulthood. Gender differences were considered unnecessary.
“Wearing a face mask can be painful. There may be a slight increase in respiratory resistance. You re-breathe warm, slightly enriched CO2 air. And if you are exercising, the mask will warm your face and make you sweat. Can cause. ” Hopkins said.
Hopkins added, “But these are sensory perceptions. They do not affect heart function in healthy people.”
“So, while dyspnea can be exacerbated by masks, you will have to weigh this against the low risk of contracting COVID-19, knowing that physiology is fundamentally unchanged.”
