Lack of physical activity is associated with negative health outcomes, including obesity, diabetes, and cardiovascular disease. A myriad of interventions aimed at increasing daily physical activity (PA) exist. Increasing PA levels has been shown to improve health among patients with cardiovascular and metabolic diseases. Accelerometers and pedometers can be useful tools in such interventions, particularly when used to provide participants with individualized feedback on progress toward PA goals. These programs typically require participants to set PA goals (e.g., number of steps/day), wear pedometers, and record daily activity levels from the pedometers. This process relies heavily on accurate self-reported information and is both time- and effort-intensive for participants, thus limiting acceptability and longer-term viability of this intervention option.
