Exclusion criteria: 1) Patients who have difficulty walking for 6 minutes due to neurological or orthopedic disorders 2) Patients who are contraindicated in the 6-minute walking test (Unstable angina within 1 month, myocardial infarction, stable angina, resting HR is 120/min or more, systolic blood pressure is 180mmHg or more, or diastolic blood pressure is 100mmHg or more) 3) Patients who have been diagnosed with heart failure and are being treated for heart failure 4) Patients who are judged to be ineligible at the discretion of the investigator

Design outcomes

Primary

Measure	Time frame
Differences in 6-minute walking distance between subjects with and without a surgical mask	—

Secondary

Measure	Time frame
Comparison of resting SPO2 values with and without a surgical mask Comparison of lowest SPO2 values during exertion with and without a surgical mask Comparison of max HR values with and without a surgical mask Distance and time to achieve SPO2 < 90% with and without a surgical mask Comparison of the Borg Scale during 6-minute Walking with and without a Surgical Mask Clinical characteristics of patients with or without a 6-minute walk distance greater than Minimal Clinically Important Difference (MCID) with or without a surgical mask Clinical characteristics of patients with and without a surgical mask whose Borg scale was larger than or equal to MCID Clinical characteristics of patients with and without a surgical mask whose SPO2 fell below 90%	—
