Virtual coaching and social support to help maintain exercise after cardiac rehab

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized trial will enroll 286 adults aged 55 and older who are completing outpatient Phase II cardiac rehabilitation. All participants use the Trainerize mobile app for daily self-monitoring of exercise, blood pressure, and weight plus weekly educational texts and monthly health videos, while the STRIVE+ intervention group also receives individually tailored virtual coaching, goal-setting, and social networking. Primary outcomes include objectively measured steps and sedentary time, with secondary measures of functional fitness, self-reported exercise, depression/loneliness, self-efficacy, and perceived social support. Investigators will also analyze whether changes in psychosocial and social-cognitive factors mediate any effect on activity adherence, with assessments conducted through UCSF follow-up visits.
