Despite the gym closings and the inconsistencies with the locks Maintaining a healthy lifestyle is an important strategy to protect yourself during the coronavirus pandemic1.
Even if social media chatters and opinions disagree, the reality doesn’t change: The U.S. Centers for Disease Control and Prevention recommends wearing a fabric mask or face covering in public, especially in places who have difficulty maintaining social distance, and mass masking An inexpensive and easy way to complement social distancing and other methods of controlling infection rates.
Research also shows that gyms are a source of virus transmission2, like many other public spaces, and this masking should be part of the practice and training experience. This is especially true if the activity is aerobic3.
Researcher at the Rambam Health Care Campus in Haifa, Israel, have investigated the physiological effects of face masks during exercise evaluate the impact on the trainee.
They found that masking during aerobic exercise had minimal and statistically inconsistent effects on heart rate, breathing rate, breathing, and blood oxygen saturation.
However, use of an N95 ventilator indicated an increase in EtCO2 (Endtidal Carbod Dioxide) values, a measure of carboxy dioxide production and clearance with breathing. This increase could also be explained by the fact that when a mask is worn, the exhaled air is inhaled again.
Granted, airway exposure to elevated levels of carbon dioxide can degrade performance, cause headaches, confusion, stupor, and increases in heart and breathing rates.
Short-term and intermittent exposure can also lead to improvements in respiratory muscle development and better performance.
The research does not examine the effects of wearing masks from a psychological point of view and is not broad enough to draw specific conclusions about any particular populations, given that it is an all-male group of subjects. It is therefore best not to generalize the results.
But you can just stay out of the slipstream of anyone exercising vigorously and keep your distance 4th.
It used to be called an ounce of prevention that today looks like a million years ago, at a time when people’s opinions about anything are extremely polarized.
