Effects of short-bout accumulated physical activity and sedentary-break interventions on continuous glucose monitoring metrics in adults with type 2 diabetes: A systematic review and meta-analysis.

Glycated hemoglobin does not fully capture postprandial hyperglycemia or intraday glycemic fluctuation, whereas continuous glucose monitoring (CGM) characterizes mean glucose, hyperglycemic exposure, and glycemic variability. Short-bout accumulated physical activity and sedentary-break interventions are low-burden strategies that can be integrated into daily routines, but their overall effects on CGM-derived outcomes in adults with type 2 diabetes remain uncertain. We systematically reviewed and quantitatively synthesized these effects.
