Adult, Exercise, Middle Age, Sedentary Behavior
Conditions
Brief summary
The proposed study will test the preliminary efficacy of a novel 12-week social cognitive theory-based intervention that will target reducing daily sitting time and increasing exercise participation among middle-aged working adults. This is a population highly susceptible to excessive sedentary time and low levels of exercise engagement. This two-arm randomized controlled trial (RCT) will examine the preliminary efficacy of decreasing sedentary time in addition to increasing moderate-vigorous intensity physical activity (MVPA) engagement, compared to a group which only receives MVPA promotion.
Interventions
BEHAVIORALDecrease Sedentary Time + Increase MVPA group
12 week home-based exercise program to promote engagement of 150 min/week of moderate-vigorous intensity exercise; personalized step count goals to increase daily volume of physical activity and displacement of sedentary time
BEHAVIORALIncrease MVPA group
12 week home-based exercise program to promote engagement of 150 min/week of moderate-vigorous intensity exercise

Inclusion criteria
* 45-65 years of age by study start date * Hold full-time employment (≥ 30 hours/week) at one or more jobs * Hold a sedentary-based job (which also allows for ability to freely move about during the workday) * Low active (engage in ≤2 days of 30+ minutes of structured moderate-vigorous intensity exercise/week) * Physician's consent to participate in aerobic testing and/or the exercise program (if needed based on Physical Activity Readiness Questionnaire responses) * Ambulatory * Absence of health conditions that may be made worse by exercise * Ability to complete all testing assessments in-person * Access to a laptop/desktop/phone with Zoom web-conferencing software * Fluent in English
Exclusion criteria
* Under 45 or over 65 years of age * Not holding full-time employment (work \< 30 hours/week at one or more jobs) * Hold a job(s) which is classified as light, medium, heavy, or very heavy work * Hold a sedentary-based job which does not allow for free movement throughout the workday (i.e., bus driver) * High active (engage in \> 2 days or 30+ minutes of structured moderate-vigorous intensity exercise/week) * Non-consent of physician * Non-ambulatory (i.e., use of walkers, wheelchair, cane, etc.) * Presence of health conditions that may be made worse by exercise. * Unable to complete assessments in-person * No access to laptop/desktop/phone with Zoom software

Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in average daily step counts | Baseline,12 weeks | Participants will wear a hip-based pedometer for 7 days at baseline and 12 weeks |
| Changes in average daily sedentary time | Baseline,12 weeks | Participants will wear a hip-based accelerometer for 7 days at baseline and 12 weeks to measure their daily time spent sedentary. |
| Changes in average daily light-intensity physical activity | Baseline,12 weeks | Participants will wear a hip-based accelerometer for 7 days at baseline and 12 weeks to measure their daily time spent engaged in light-intensity physical activity. |
| Changes in average daily moderate-vigorous intensity physical activity | Baseline, 12 weeks | Participants will wear a hip-based accelerometer for 7 days at baseline and 12 weeks to measure their daily time spent engaged in moderate-vigorous intensity physical activity. |
