Registered outcomes9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Total Repeated-Sprint Time | During repeated-sprint testing in each of two sessions separated by at least 72 hours. | Sum of electronically timed completion times, in seconds, for five 30-meter linear sprints separated by 30-second active recovery. Lower values indicate better performance. Mask and no-mask conditions are compared within participants. |
| Secondary | Best and Mean Sprint Time | During repeated-sprint testing in each session; sessions at least 72 hours apart. | Best (minimum) and arithmetic mean electronically timed 30-meter sprint completion times, reported separately in seconds across five sprints. Lower values indicate better performance. |
| Secondary | Repeated-Sprint Performance Decrement | During repeated-sprint testing in each session; sessions at least 72 hours apart. | Percentage decrement calculated as 100 x \[(total sprint time / (best sprint time x 5)) - 1\]. Higher percentages indicate greater performance decrement. |
| Secondary | Maximal Inspiratory Pressure | Before and immediately after exercise in each of two sessions at least 72 hours apart. | Maximal inspiratory mouth pressure (MIP), in cmH2O, obtained with a calibrated pressure device using acceptable, reproducible maneuvers. Pre-to-post exercise changes are compared between conditions. |
| Secondary | Maximal Expiratory Pressure | Before and immediately after exercise in each of two sessions at least 72 hours apart. | Maximal expiratory mouth pressure (MEP), in cmH2O, obtained with a calibrated pressure device using acceptable, reproducible maneuvers. Pre-to-post exercise changes are compared between conditions. |
| Secondary | 505 Change-of-Direction Time | During 505 testing in each session; sessions at least 72 hours apart. | Electronically timed 505 test completion time, in seconds, with right and left turning directions recorded separately. Lower values indicate better performance. |
| Secondary | Heart Rate | Before, during and immediately after exercise in each session; sessions at least 72 hours apart. | Heart rate in beats per minute recorded before exercise, during testing where signal quality permits, and immediately after exercise. Corresponding assessment points are compared between conditions. |
| Secondary | Peripheral Oxygen Saturation | Before, during and immediately after exercise in each session; sessions at least 72 hours apart. | Peripheral oxygen saturation (SpO2), expressed as a percentage, measured by pulse oximetry. Valid signals at corresponding assessment points are compared between conditions. |
| Secondary | Perceived Exertion and Breathlessness | Immediately after each field test in each session; sessions at least 72 hours apart. | Perceived exertion and breathlessness are rated separately using the Borg category-ratio 0-10 scale; higher scores indicate greater exertion or breathlessness. |
