The purpose of this study was to describe physical activity (PA) behaviors and physical functioning of prehypertensive and Stage I hypertensive African American Women (AAW) and to examine the relationships between PA behavior, physical functioning, personal factors, and behavior-specific influences. Pender’s Health Promotion Model was the conceptual framework for the study. A cross-sectional design and convenience sample were used. The PA domain where the greatest amount of time was spent was in work-related activity, followed by household, leisure time, and transportation activity. Personal factors most strongly correlated to lower PA were greater body mass index and waist circumference. AAW perceived moderate barriers to PA and minimal family and friend social support for PA. Future interventions need to focus on removing barriers to and improving social support for PA among AAW.
