Exercise in prediabetes.

Exercise as a therapeutic modality in the management of type 2 diabetes is well established. However, exercise has emerged as an important tool to prevent, or at least, to delay the onset of type 2 diabetes. This has been borne out by a few recent clinical trials. Exercise improves insulin sensitivity besides having beneficial effects on many cardiovascular risk factors. A sedentary adult at high risk for developing diabetes may benefit from at least 30 minutes of daily moderate-intensity exercise.
