Brief summary

Mask wearing during the Covid-19 pandemic has been proven substantially effective in containing the spread of infection, with cloth masks being the most universally used. However, cloth masks may be uncomfortable and have physiological repercussion during exercise. This study aims to investigate the impact of cloth masks during exercise.

Design outcomes

Primary

MeasureTime frameDescription
perceived exertion ratingsimmediately after the interventionassessed by a scale (7 to 20, with higher values meaning higher perceived exertion)

Secondary

MeasureTime frameDescription
spirometry/lung function (VeVCO2 Slope)during the interventionassessed by cardiopulmonary test
spirometry/lung function (PetCO2)during the interventionassessed by cardiopulmonary test
spirometry/lung function (OUES)during the interventionassessed by cardiopulmonary test
spirometry/lung function (flow-volume loop)during the interventionassessed by cardiopulmonary test
oxygen consumptionimmediately after the interventionassessed by cardiopulmonary test
oxygen saturationimmediately after the interventionassessed by pulse oximetry
vertical jumpimmediately after the interventionassessed by jump test
heart rate recoveryimmediately after the interventionassessed by heart rate monitor
Scale of Measuring Subjective Perceptions to maskwearingimmediately after the interventionassessed by a scale (0 to 10, with higher values meaning more uncomfortable)
