Exercise has been prescribed for diabetes treatment since at least 600 B.C. The early East Indian text, the Shushruta, described a reduction in the sweetness of urine from diabetic patients after exercise. One might think that very little could be left to discover in the field of exercise and diabetes, yet surprisingly this is far from the truth. Ongoing research is refining the exercise prescription for patients of all ages, with the main types of diabetes (gestational, type 1, and type 2) and discovering new ways in which exercise has benefits. Alterations in metabolism caused by diabetes and new types of exercise modalities are also actively being researched. A search of several hundred articles on exercise published between July 1, 2012, to June 30, 2013, uncovered the following 9 articles we felt had the most relevance to patients with diabetes or prediabetes.
