The port of the mask is a guest in our daily life since the 11th of last may. Its use is new for many of us, it requires new habits and raises many questions. The Covid-19 is transmitted mainly through droplets of saliva and the mask plays a role of barrier major, because it blocks the emission of large droplets, which prevents their release into the ambient air and the contamination of surrounding persons.
The Covid-19 is a disease that spreads, first and foremost, in the closed settings. For this reason, the wearing of the mask will be essential if you are performing a physical exercise indoors, in the company of other people, like to practice sports in the gym. The Covid-19 transmitted by the spatters, the increase in respiratory rate during the effort inevitably generates a strong increase of the emission of droplets into the ambient air, which, in a confined environment, could represent a major risk of contamination. The practice of outdoor sports exhibits significantly less at risk of being contaminated, or contaminate, the spread of the virus to be less obvious.

This does not pose problems, except possibly for a sport at high intensity. However, it would be prudent for those who suffer from chronic illnesses cardiac or respiratory limit the intensity of the effort, in order not to run any risk. In addition, the increase in the respiratory rate will wet much more quickly the mask, either surgical or fabric. This is not without consequences, since moisture alters the qualities of filtration of the mask. More the mask will be wet, and the harder it will be to breathe comfortably. Therefore, it is recommended and desirable to obtain a second mask in order to change over the course of the sequence sports. The handling of the mask is soiled is likely to drop the virus on your fingers, be sure to bring with you a small vial of aqueous-alcoholic solution so that you disinfect the hands.
