Key Points Question What is the relative effectiveness of offering structured exercise sessions in improving diabetes control? Findings In this 3-group randomized clinical trial, 357 adults with type 2 diabetes were advised to follow American Diabetes Association physical activity guidelines and randomized to usual care or once-weekly vs thrice-weekly structured exercise. There was no significant difference in hemoglobin A1c in the intention-to-treat analysis, and hemoglobin A1c was lowered only for participants in the thrice-weekly structured exercise program who attended at least 50% of the recommended exercise sessions. Meaning These findings suggest that future efforts should focus on improving adherence to thrice-weekly structured exercise programs to meet exercise guidelines.
