Since the 1960s, there has been a change in the portrayal of older people. This change has resulted in the promotion of an active way of life that led, at the turn of the twenty-first century, to the development by international bodies of standard guidelines relating to active or healthy ageing. This article examines the place of guidelines on physical activity in the perception of ageing reflected in French public policies developed in accordance with international directives. After explaining how healthy and active ageing are defined in different international and national plans and official guidelines, the growing importance of physical activity is highlighted. From a very general invitation to remain active, precise instructions for physical activities were established addressing the detrimental effects of ageing. Finally, this study points out how the increasing focus on physical activity has contributed to the creation of a frame of reference in public policy that emphasizes the responsibility of each individual for their own health.
