Physical activity is widely considered to be a significant contributing factor to how “successfully” one ages. There are, however, certain groups whose voices have not been widely heard in discussions around physical activity and aging, particularly those from diverse cultural backgrounds. In this research, we explored how Alaska Native Elders perceive the role of physical activity as they age and its contribution to successful aging. Based on semi-structured interviews with 41 Elders, the results show that engaging in physical activity was not just seen as a personal responsibility to maintain health and age successfully, but also as a way to resist Western society’s dominant view of older adults as deteriorating and declining by being physically active regardless of age; to improve or maintain their physical, mental, emotional, and spiritual health; and/or to enable them to continue participating in subsistence activities that are rooted in their culture and traditional roles as Elders.
