Treadmill Stress Test With and Without Mask

Not Applicable

Completed

• Conditions: Healthy
• Interventions: Diagnostic Test: Treadmill test (Bruce protocol)

• Registration Number: NCT04891120
• Lead Sponsor: Université de Sherbrooke

Brief Summary

The purpose of this study is to assess if wearing a surgical mask affects the results of a standard treadmill test.

Detailed Description

The persons interested to participate will be informed of the implication and potential risks associated with the study. The participants that accept and meet the eligibility criteria will give written consent and be randomized into two groups. One group will first perform a treadmill test with a surgical mask and then repeat the test without a mask. The second group will do the first treadmill test without a mask and the second one with a surgical mask.

Primary Outcome Measures

Name	Time	Method
Change in Metabolic Equivalents With vs Without a Mask	Through study completion, an average of 1 week	The maximal metabolic equivalents achieved will be calculated for each treadmill test performed.

Secondary Outcome Measures

Name	Time	Method
Change in Borg's Category-Ratio Scale for Rating of Perceived Exertion With vs Without a Mask	Through study completion, an average of 1 week	The Borg Scale is a self-reporting instrument assessing intensity of perceived exertion on a 0 to 10 scale, 0 being rest and 10 maximal effort.
