The medical advice for Type II Diabetics and pre-Diabetics has consistently been to maintain a good weight, eat the correct diet - low fat, lo carb, high protein and fiber, and do aerobic exercise.

So, unless this advice is totally off base, what i REALLY want to know from a study is if Taijiquan, Qi Gong, or a combination of both is any better than any other form of exercise program at helping to control a person's Diabetes.

To this end, you really would not have to include the non-exercise group unless you wanted to lay a baseline of "See, exercise in and of itself does a lot of good..." This would then get you out of the ethical problem os "withholding treatment" even though a large number of people with Type II Diabetes or pre-Diabetes are already couch potatoes.

Now, maybe I am just sensitized...living in Houston with a couple of very large medical schools and a large well known medical center... Quoting a study like this in justifying why to take up Taijiquan over some other program will basically get your lunch eaten.
