Physical inactivity in the United States has become a critical public health concern for all age groups. With a large segment of the population rapidly aging, there is growing interest in ensuring mid to older age adults (50+) stay active and reduce sedentariness, to decrease their morbidity and mortality risk. While older adults are advised to engage in at least 150 minutes/week of moderate to vigorous physical activity (PA), most do not. Specific theory based behavioral strategies have been shown to positively affect health and activity behaviors. There is also emerging evidence that mindfulness based interventions (MBI) may facilitate PA through increased mind-body awareness and self-regulation. However, research for MBIs and physical activity is currently limited, both in quantity and methodological rigor.
