Background: While there is substantial evidence on the relationship between life satisfaction and present physical activity (PA), less is known about which specific PA biographies are associated with a high quality of life and aging satisfaction. Our objective was to identify classes of PA biographies that may be associated with life and aging satisfaction. Methods: In this longitudinal study, PA biographies were assessed retrospectively as a baseline, followed by assessments of life and aging satisfaction at six and twelve months in 418 adults aged 60–95. Subgroups with different PA biographies were identified using latent class analysis. Results: Four distinct PA biographies emerged: increasingly active (35%; n = 147); consistently active (25%; n = 103); consistently inactive (18%; n = 75); and decreasingly active (22%; n = 94). Being consistently active was related to life satisfaction (β = .17) and consistent inactivity was associated with aging dissatisfaction (β = −.20) when accounting for current PA levels. Conclusions: In addition to current PA, our findings emphasize the value of PA biographies for life and aging satisfaction, which could inform lifespan theories of PA and health promotion
