The principle barriers preventing health care professionals from promoting physical activity include an incomplete understanding of the evidence linking physical activity and health, difficulty in translating research findings into a feasible and efficacious clinical intervention, resistance to adopting a preventive orientation, and concerns about the risks of physical activity.
