Targeted Health Coaching to Improve Physical Activity Post-Structured Cardiac Rehabilitation

Approximately 800,000 individuals in the United States have a heart attack every year, with almost 1 in 4 of those individuals already having suffered a previous heart attack. Attending cardiac rehabilitation (CR) following a cardiovascular event improves cardiorespiratory fitness and health-related quality of life, as well as decreases the risk of future illness and death from heart disease. Unfortunately, once an individual finishes a CR program, continued participation in physical activity (PA) too often reverts to previous sedentary patterns, limiting beneficial health effects. Continued participation in PA post-CR is especially challenging among older adults - likely due to a lack of self-efficacy and confidence in their ability to perform PA due to either their age or other health conditions that make PA more challenging. However, the need to address other health conditions, in conjunction with the benefits of improved strength and mobility, makes continued PA participation following a structured CR program even more useful for older adults. Although individuals typically understand habitual participation in PA is good for their health, we poorly understand why some individuals successfully adhere to and maintain PA habits, while others succumb to barriers preventing them from maintaining the health benefits beyond CR. In addition to understanding factors and triggers influencing PA maintenance beyond CR, little research has developed or investigated interventions targeting this important transition period following structured CR programming to promote continued PA participation "at home". Therefore, this proposal aims to 1) identify factors and triggers influencing PA participation after a traditional 36-session CR program (Stage 0); and 2) test a targeted health coaching intervention using these identified triggers to optimize PA maintenance and mobility among older adults who completed a center-based CR program.
