Purpose:
The primary aim of this study was to assess the feasibility of an exercise counseling intervention for adults of diverse race/ethnicity with heart failure (HF) and to assess its potential for improving overall physical activity, functional capacity, and HF self-care.
Design:
This study was a quasi-experimental, prospective, longitudinal cohort design.
Methods:
Twenty adults were enrolled and completed the 6-minute walk and standardized instruments, followed by exercise counseling using motivational interviewing. Each received an accelerometer, hand weights, and a diary to record self-care behaviors. Participants were followed via phone for 12 weeks to collect step-counts, review symptoms, and plan the following week's step goal.
Findings:
Results indicate that this intervention was feasible for most participants and resulted in improvements in physical activity, functional capacity, and self-care behaviors.
Conclusion/Clinical Relevance:
Brief exercise counseling may be an appropriate option to improve outcomes for stable patients with HF and may be tailored to fit different settings.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
