The subjective, lived elements of old age in physical activity promotion are central in defining how older people ascribe meaning to experiences of being active. Many such meanings are developed throughout the life course. From a longitudinal perspective, although continuity theory can be helpful in understanding older people’s sense of self and personal change, its focus on the individual can underplay the substantive influence of socio-cultural factors on the way age and ageing are understood. Using a figurational sociological framework, we illustrate how older peoples’ sense of self can be interdependent with how others define them, and how they define others. We offer recommendations about how this shift in perspective can empower older people to be active agents within figurations of physical activity promotion.
