The goal of this randomized controlled trial is to investigate the effectiveness of a health-coaching intervention to improve physical activity in older adults with limited mobility when compared to a control, health education group.
A total of 290 older adults with limited mobility will be randomized to either a 26-week health coaching program or health education program. Outcomes will be assessed at baseline, 13-weeks, 26-weeks (end of intervention), and 52 week (6-month follow-up period).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Health Coaching (HC) | Experimental | The health coaching program will be delivered by trained and certified kinesiologists utilizing Brief Action Planning (BAP) principals. The BAP behavior change approach utilizes the following 4 techniques: 1) goal-setting; 2 )action planning; 3) self-monitoring; and 4) feedback. Participants will utilize daily physical activity diaries to enable self-monitoring, and BAP coaches will provide feedback on progress toward individualized physical activity goals. |
|
| Health Education Program (ED) | Active Comparator | This program is an attention control group, which consists of general health education. Education sessions will be delivered either by zoom or in person. The education sessions will cover the following topics: 1) falls prevention; 2) sleep; 3) healthy eating; 4) cognitive health; and 5) mental and emotional health. |

| Health Coaching Program | Behavioral | The HC program will be delivered over 26-weeks. Participants will have an initial hour-long HC session where the BAP coach will conduct a brief physical assessment and work with the participant to establish their physical activity goals and develop a plan. After the initial consult, coaches will conduct 8 x 20-minute phone calls with participants over the 26-week trial decreasing from bi-weekly phone calls in weeks 1-12 to monthly phone calls in weeks 13-26. Participants in the HC group will have an overall goal of increasing their weekly participation in moderate to vigorous physical activity by 50 minutes, via 5-, 7-, or 10-minute bouts of progressive exercises, at a rate of perceived exertion range of 13-14 ("somewhat hard") by week 16. Participants will have access to specific exercise sessions made available by YouTube and/or hardcopy manuals created by the research team. |

| Health Education Program | Behavioral | Participants will begin with a one-hour, group-based, interactive education session on falls prevention delivered either in-person or by Zoom. Following the initial education session, ED participants will receive additional group education sessions (in-person or by Zoom) with the same duration and schedule as the HC program covering a variety of healthy aging topics. |
