Brief summary
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.
Detailed description
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).
Interventions
BEHAVIORALHealth Coaching Program
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.
BEHAVIORALHealth Education Program
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.
