Wearing a face mask during exercise safe for healthy people: Study ANI | Updated: Mar 08, 2021 10:39 IST Washington [US], March 8 (ANI): According to a new study, wearing a face mask during intense exercise is safe for healthy people and could reduce the risk of COVID-19 spreading at indoor gyms. The findings of the study were published in the European Respiratory Journal. For the study, researchers carried out detailed testing on breathing, heart activity, and exercise performance in a group of 12 people while they were using an exercise bike with and without a mask. Although they found differences in some measurements between wearing a mask and not wearing a mask, the researchers noted that none of their results indicated any risk to health.
