Registered outcomes8
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Prefrontal Cortex Oxygenation | All throughout each 5-kilometer cycling time trial, approximately 10 minutes | Changes in prefrontal cortex oxygenated hemoglobin were continuously measured using functional near-infrared spectroscopy during 5-kilometer cycling time trials performed with and without the Q-Collar. Data were evaluated across kilometer time points. |
| Secondary | Cycling Time-Trial Performance | At completion of each 5-kilometer cycling time trial, approximately 30 seconds | Time in seconds required to complete the 5-kilometer cycling time trial was recorded for the Q-Collar and control conditions. |
| Secondary | Choice Reaction Time | At baseline, 5 minutes into exercise, immediately post-exercise, and 10 minutes post-exercise during each experimental visit, approximately 2 minutes at each time point | Choice reaction time was assessed using a computerized Stroop task. Reaction time and response accuracy were evaluated across the Q-Collar and control conditions. |
| Secondary | Heart Rate | During each 5-kilometer cycling time trial, approximately 10 minutes | Heart rate was continuously assessed using cardiac impedance and compared across the Q-Collar and control conditions. |
| Secondary | Stroke Volume | During each 5-kilometer cycling time trial, approximately 10 minutes | Stroke volume was continuously assessed using cardiac impedance and compared across the Q-Collar and control conditions. |
| Secondary | Cardiac Output | During each 5-kilometer cycling time trial, approximately 10 minutes | Cardiac output was continuously assessed using cardiac impedance and compared across the Q-Collar and control conditions. |
| Secondary | Blood Lactate | Immediately following each 5-kilometer cycling time trial, approximately 1 minute | Blood lactate concentration (mmol/L) was measured from an earlobe capillary blood sample immediately following each cycling time trial. |
| Secondary | Rating of Perceived Exertion | Immediately following each 5-kilometer cycling time trial, approximately 30 seconds | Rating of perceived exertion was assessed using the Borg 6-20 scale immediately following each 5-kilometer cycling time trial. |
