OBJECTIVETo evaluate the impact of an exercise program organized into supervised walking groups in subjects with type 2 diabetes.RESEARCH DESIGN AND METHODSFifty-nine diabetic subjects were randomized to a control group receiving standard lifestyle recommendations or an intervention group assigned to three supervised walking sessions per week and counseling. Changes in metabolic features, weight, 6-min walk test, prescription of antidiabetic medications, and overall physical activity were assessed.RESULTSFunctional capacity and overall physical activity were higher in the intervention group, whereas metabolic changes were not different between groups after 4 months. However, in subjects who attended at least 50% of scheduled walking sessions, changes in A1C and fasting glucose were greater than in control subjects. Discontinuation or reduction of antidiabetic drugs occurred in 33% of these patients versus 5% of control subjects (P < 0.05).CONCLUSIONSSupervised walking may be beneficial in diabetic subjects, but metabolic improvement requires adequate compliance.
