Human behavioral basis for recommending changes to the physical activity guidelinesOA

A growing body of evidence supports the central role of human behavior and affect in the promotion of physical activity(PA),yet a persistent gap remains between PA guidelines and actual population levels of PA.Over the past three decades,public health initiatives have focused on disseminating information about the health benefits and recommended doses of PA through top-down guidelines.However,these efforts have not consistently translated into meaningful increases in PA participation.Accumulating evidence indicates that human behavior is not governed solely by rational cognitive evaluations.In this commentary,we argue that PA guidelines should extend beyond epidemiological recommendations to explicitly incorporate behavioral and psychological dimensions.Our rationale draws on theories of behavior change,motivation,basic psychological needs,and affective responses to PA.The immediate subjective experience of movement plays a critical role in determining the likelihood of future engagement,as affective responses during PA are intrinsically linked to adherence.Therefore,in addition to cognitive-based messaging,PA communication strategies should emphasize affective components and highlight short-term benefits,particularly those related to social connection and mental wellbeing.
