- W4387061919 abstract "Face masks reduce the spread of respiratory disease, and their use has been mandated throughout the COVID-19 pandemic. Physical exertion increases the distance traveled by expelled particles, therefore masking while exercising is recommended to help prevent transmission. However, there is limited literature assessing the influence of masking during exercise. PURPOSE: To investigate how the use of surgical masks while exercising at different intensities affects physiological and subjective measures. METHODS: After assessing VO2max, each subject completed two, forty-five-minute exercise trials (fifteen minutes at 40%, 60%, and 80% their VO2R) in which face mask usage was randomly assigned to either a surgical mask or no mask. Heart rate (HR), oxygen saturation (SpO2), respiratory rate (RR), ratings of perceived exertion (RPE), and dyspnea (Dys) were measured twice at each intensity. Dependent T-tests were conducted using SPSS (Version 27) and significance was set at p < .05. RESULTS: Thirty subjects (age: 20.4 ± 1.2 years; VO2max: 40.12 ± 11.05 ml/kg/min, 57% female) completed the study. When comparing masked and unmasked trials at each exercise intensity, differences were found in HR, SpO2, and RPE at 80% intensity (HR: 179.3 ± 11.1 vs. 176.7 ± 11.8. p = 0.03; SpO2: 94.5 ± 1.5 vs. 95 ± 1.4, p = 0.04; RPE: 17.3 ± 1.4 vs. 16.7 ± 1.6, p = 0.03), respectively. Differences were found in RR and Dys at all intensities (RR 40%: 17.6 ± 4.9 vs. 15.8 ± 4.9, p = 0.02, 60%: 23.7 ± 5.5 vs. 21.3 ± 6.2, p = 0.01, 80%: 35.8 ± 9.0 vs. 30.1 ± 8.8, p = 0.00), (Dys 40%: 1.2 ± 0.6 vs. 0.9 ± 0.6, p = 0.00, 60%: 3.1 ± 0.9 vs. 2.6 ± 1.0, p = 0.00, 80%: 6.05 ± 1.8 vs. 5.19 ± 1.7, p = 0.00). CONCLUSIONS: The use of surgical masks appears to impact HR, SpO2, and RPE at higher intensities, and Dys and RR across all intensities. However, these differences did not alter exercise time or pose a health risk to these healthy subjects. Therefore, we encourage the use of face masks in exercise facilities when there is an increased risk of spreading an airborne disease." @default.
