ABSTRACT
ABSTRACT Introduction:
Due to the mandatory use of a mask, and the authorization to do outdoor sports in Catalonia, we try to assess the physiological impact of the hypercapnia hypoxia generated by the masks during aerobic sports practice.Methods:
Eight subjects (2 women) were assessed at baseline with and without a mask, and then a 21-flex test was performed following the Ruffier protocol with a mask. Control of HR (heart rate), concentration of O2 and CO2 inside the mask and SatO2. The test was carried out in ambient air in squares in the city of Barcelona.Results:
A decrease in O2 was recorded comparing the three conditions, baseline 20.9%, baseline mask 18.3%, post-exercise 17.8% (p <0.001). An increase in CO2 in the three preconditions (464, 14162, 17000 ppm;p <0.001). Basal saturation O2 was 97.6 ± 1.5% and post exercise 92.1 ± 4.12% (p 0.02).Conclusions:
The use of masks in athletes causes hypoxic and hypercapnic breathing, being more evident in effort. The use of masks during a short exercise with an intensity around 6-8 METS, decreases O2 by 3.7% and increases the CO2 concentration by 20%.
