Abstract

Recommended levels of physical activity may represent challenging targets for many older adults at risk for disability, leading to the importance of evaluating whether low-intensity activity is associated with health benefits. We examined the cross-sectional association between low-intensity walking activity (<100 steps/min) and health and physical function in a group of older adults. Participants (N = 187; age = 66.8; 91.4% African American; 76.5% female) wore a StepWatch Activity Monitor to measure components of low-intensity walking activity. Only 7% of participants met physical activity guidelines and moderate-intensity activity (≥100 steps/min) contributed only 10% of the total steps/day and 2% of the total min/day. Greater amount, frequency, and duration of low-intensity activity were associated with better self-report and performance-based measures of physical function, better quality of life, and fewer depressive symptoms (ps <.05). The cross-sectional relationship between low-intensity activity and health outcomes important to independent function suggests that we further explore the longitudinal benefits of low-intensity activity.
