Brief summary
There are two main aims for this study: 1. conduct a proof-of-concept study illustrating how radio-frequency identification technology can be used to document the timestamps and duration of stair walking (ascending and descending stairs), and detect if an individual is stationary in the stairwell. 2. assess the association of a 4-min bout of self-paced stair walking with changes in blood pressure, mood, and perceived exertion.
Detailed description
Objective, passive methods for measuring physical activity participation can minimize error associated with self-report bias and cognitive processing. This study will test the utility of radio frequency identification (RFID) for the measurement of stair walking within buildings. RFID readers will be placed at stairwell entrances on each floor. Participants will wear a RFID tag. As the participant walks past the different readers going up and down the stairs, the reader will log the date and time. The frequency and duration of time in the stairwell can be calculated, as can an estimated speed. There are known effects for blood pressure (hypotensive) and moodafter exercise. However, few studies have assessed this effect for short bouts (\<10 minutes) of exercise. Participants will have their pre- and post-stair walking blood pressure measured to determine the hypotensive and mood enhancing effects of four minutes of stair walking at a comfortable pace. Participants also will rate the exertion level of four minutes of stair walking at a self-selected pace.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Stair walking duration | Calculated after the completion of the 4-minute stair walking episode | Duration, in seconds, of stair walking as tracked by the RFID equipment |
| Stair walking distance | Calculated after the completion of the 4-minute stair walking episode | Distance, in number of stairs climbed, as tracked by the RFID equipment |
| Stair walking speed | Calculated after the completion of the 4-minute stair walking episode | Speed of stair walking, in stairs per second based on duration and distance, as tracked by the RFID equipment |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mental Fatigue | Before and immediately after stair walking | Measured by self-report using the State Energy and Fatigue Scale. There are 3 items, scored using a number line from 0 to 100, that are summed to generate a score, where higher scores indicate greater mental fatigue. |
| Blood Pressure | Before stair walking and 2-minutes and 5-minutes post stair walking | Systolic and diastolic blood pressure |
| Physical Fatigue | Before and immediately after stair walking | Measured by self-report using the State Energy and Fatigue Scale. There are 3 items, scored using a number line from 0 to 100, that are summed to generate a score, where higher scores indicate greater physical fatigue. |
| Physical Energy | Before and immediately after stair walking | Measured by self-report using the State Energy and Fatigue Scale. There are 3 items, scored using a number line from 0 to 100, that are summed to generate a score, where higher scores indicate greater physical energy. |
| Borg's Rating of Perceived Exertion | Immediately after stair walking | A one-item measure of a participant's perceived physical effort during an activity. Responses range from 6 (no exertion) to 20 (maximal exertion), where higher scores indicate a greater perceived exertion. |
| Mental Energy | Before and immediately after stair walking | Measured by self-report using the State Energy and Fatigue Scale. There are 3 items, scored using a number line from 0 to 100, that are summed to generate a score, where higher scores indicate greater mental energy. |
