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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
Other
| Measure | Time frame |
|---|---|
| Change in Blood Pressure During Exercise With vs Without a Mask | Through study completion, an average of 1 week |
| Change in Oxygen Saturation During Exercise With vs Without a Mask | Through study completion, an average of 1 week |
| Change in Exercise Duration With vs Without a Mask | Through study completion, an average of 1 week |
| Change in Calculated Maximal Oxygen Consumption During Exercise With vs Without a Mask | Through study completion, an average of 1 week |
| Change in Duration of Exercise Before Reaching 85% of Predicted Maximal Heart Rate With vs Without a Mask | Through study completion, an average of 1 week |
| Change in Heart Rate During Exercise With vs Without a Mask | Through study completion, an average of 1 week |
