Researchers evaluated dyspnea and standard respiratory function before and after the intervention.
Researchers have observed a gradual decrease in FEV1 FVC from exercise without face mask (3.94 and 4.7 respectively) to exercise with surgical mask (3.23 and 3.77 respectively) and exercise with FFP2 mask (2.94 and 3.52 respectively). P According to the result, <. 001 (for comparison).
In addition, researchers observed gradually lower VOs.2 Uptake and CO2 Production with decreased respiratory rate.
During peak exercise, participants had a higher degree of dyspnea as assessed on the Borg scale when wearing surgical masks and FFP2 masks (5 and 9, respectively). Also, in peak exercise, VO2 Incorporation (31, 27.5, 28.2, respectively; P = .001), ventilation (92, 76, 72, respectively; P = .003), respiratory rate (42, 38, 37, respectively; P = .04) and tidal volume (2.28, 2.05 and 1.96, respectively; P = .001) gradually decreased from not wearing a face mask to wearing a surgical mask and wearing an FFP2 mask.

While waiting for people to come Vaccination against COVID-19, This discovery can have a practical impact on daily life. For example, opening an indoor gym can be safer, “Mapelli said in a related press release. “But the same is not true for people with heart or lung conditions. Further research is needed to investigate this question.”
No adverse events have been reported. The researchers found no significant difference in oxygen saturation while wearing the mask.
The researchers said the study was small and was conducted only in healthy middle-aged adults. Therefore, the results are tentative and should be reviewed by a larger group.
According to the release, further research on the effects of wearing a face mask is underway not only in patients with heart and lung conditions, but also in healthy individuals who perform daily activities such as climbing stairs and doing household chores.
