ABSTRACT=Background:  Although many people know that an active lifestyle contributes to health they fail to translate their intentions into action.  This has been explained by deficits in self-management and resources, such as enabling social support, planning and self-regulation in the face of barriers.  The present study examines the role of perceived social support, planning, and self-regulation in facilitating physical activity. 
Methods:  In a prospective online study, intention was assessed at baseline (Time 1), planning and social support at 4-week follow-up (Time 2), self-regulation and physical activity at 6-month follow-up (Time 3).  A path analysis was conducted to shed light on mediating psychological mechanisms contributing to maintenance of physical activity. 
Results:  Perceived support (Time 2), planning (Time 2) and self-regulation (Time 3) mediated the link from intention (Time 1) to physical activity (Time 3); the specific and total indirect effects were significant. 
Conclusions:  Findings suggest that perceived social support, planning and self-regulation can bridge the intention-behavior gap.  Behavior change interventions should target those mechanisms in vulnerable individuals
