Heart disease is a leading health concern and cause of death in older adults. Physical activity is an essential lifestyle component for the prevention of heart disease. The number of steps per day is a simple metric for promotion of physical activity and walking is an activity which most older adults can participate. Despite the clinical and public health utility of steps/d for promoting physical activity there is no evidence-based step public health recommendation. To advance the field, Dr. Paluch will investigate the volume and walking pace of steps per day associated with heart health among older adults. The objective of her study is to identify the total number of steps per day to benefits heart health and determine if walking faster has additional benefits.  This project will also evaluate the feasibility and acceptability of delivering remote wearable technology focused walking interventions to older adults. The long-term goal of her research is to advance clinical and population health promotion of physical activity and establish an easy to implement step-based interventions for longer, healthier lives.
