How does exercise reduce the risk of diabetes (and which type)?

What will be an ideal response?

Exercise is especially important as a prevention strategy for those at high risk of developing Type 2 diabetes, such as individuals with metabolic syndrome. Recently, the American College of Sports Medicine and the American Diabetes Association issued a joint position statement in which they concluded that "high-quality studies establishing the importance of exercise and fitness to diabetes were lacking until recently, but it is now well established that participation in regular PA [physical activity] improves blood glucose control and can prevent or delay T2DM [Type 2 diabetes], along with positively affecting lipids, blood pressure, cardiovascular events, mortality, and quality of life.".

Based on research from the Nurses' Health Study, Hu and his colleagues estimated that 87% of new cases of Type 2 diabetes in women could be prevented through maintaining a healthy diet, normal weight, and regular exercise. For those who already have Type 2 diabetes, aerobic exercise yields benefits in controlling blood sugar, but adding resistance training alongside a weekly aerobic routine is even more effective.
