Abstract
Objective: This study aimed to examine the influence of wearing different types of face masks on the results of the 6-Minute Walk Test (6MWT) in a cohort of healthy volunteers. Materials and Methods: Volunteers were partitioned into three groups (each comprising 36 individuals) with different mask-wearing conditions: NIOSH-approved N95 mask, and double-mask scenarios featuring two layers of surgical mask, and a combination of a surgical mask covered by a cloth face mask. Each participant performed two rounds of the 6MWT, one while wearing a mask and another without. Various metrics, such as the six-minute walk distance (6MWD), oxygen saturation (SpO2), and dyspnea and fatigue scores, were measured. Results: No significant differences were found in the 6MWD results between the mask-wearing and non-mask-wearing scenarios across all the mask types. Strong positive correlations were also established between the 6MWD results in the mask-wearing and non-mask-wearing conditions. However, a small cohort experienced dyspnea significantly more when wearing double surgical masks compared to not wearing a mask. Additionally, there were no major deviations in SpO2 levels or fatigue scores regardless of the type of mask used. Conclusion: The study indicated that wearing an N95 mask, or double surgical masks, or cloth-over-surgical face masks did not significantly influence the outcomes of the 6MWT in healthy individuals. However, caution is advised in the case of wearing double surgical masks, as this may induce a greater sense of dyspnea. This suggests that face masks can be worn safely during physical fitness and pulmonary function assessments, aligning with their essential role in viral spread prevention in daily life.
