[Physical activity as a therapeutic tool in type 2 diabetes: practical aspects].

Physical activity is an integral part of the therapeutic management of type 2 diabetic patients. Its beneficial effects on patients' metabolic control and quality of life are well recognized. The clinical intervention is based on two complementary approaches: to promote physical activity and/or to decrease sedentary behavior, with the aim of long term maintainance. Careful examination of the patient, and assessment of his/her physical capacity and potential risks associated with activity represent the first steps. Assessment of the patient's motivation and stage of change regarding physical activity appears to be a key element for the success of the physical activity project. Main objectives should be clearly defined, as well as the means to reach them (changes in every day-life activities, progressive structured physical exercise), and should be reevaluated and adapted on a regular basis, together with the patient, and whenever possible, with his/her familial/social environment.
