About

Regular physical activity is important for the treatment of type 2 diabetes, but it is often not sustained for many reasons, including lack of interest. New video games that involve physical movement ("exergames") may help in this regard. This study will compare the "exergame" "Dance Dance Revolution" (DDR) with traditional treadmill exercise on blood sugar control among sedentary, overweight or obese adults with type 2 diabetes.

Full description

This study is a randomized, controlled trial of a 3-month ad libitum program of the "exergame" "Dance Dance Revolution" (DDR) versus traditional treadmill exercise. Each group of subjects will be assessed at baseline, and then assigned exclusively to one of the two exercise modalities. Subjects will be free to attend exercise sessions in their assigned exercise modality at the exercise facility, at a frequency, duration and intensity of their own choosing with minimal staff supervision, for a period of exactly 90 days; adoption of new exercise programs outside of the study will be prohibited. Dosages of any concurrent medications will be maintained constant, and all subjects will receive standardized nutrition counseling.

Inclusion criteria

Age 18 to 65 inclusive
Diagnosed type 2 diabetes mellitus (by ADA diagnostic criteria) for at least 1 year
On stable doses of oral anti-hyperglycemic medications for at least 3 months (i.e., sulfonylureas, metformin, thiazolidinediones, and/or DPP-4 inhibitors; GLP-1 analogues may also be permitted)
Hemoglobin A1c level between 7.5% and 9.0% inclusive
Body mass index (BMI) between 25.0 and 40.0 kg/m2 inclusive
Able to engage in a regular program of mild-to-moderate intensity physical activity
Subjects not currently engaged in any regimented exercise program outside of the usual activities of daily living that is intended to achieve metabolic changes (e.g., weight loss, athletic training, etc.)
Able to give informed consent and cooperate with all necessary procedures of the study

Exclusion criteria

Any contraindications to a regular program of mild-to-moderate intensity exercise, or any cardiovascular, pulmonary, orthopedic, rheumatological or neurological conditions that may, in the opinion of the investigators, interfere with the subject's optimal participation in a regular exercise program, interfere with the quality of the data collected from the subject, or make a regular exercise program potentially hazardous
Diabetes mellitus currently being treated with insulin and/or pramlintide
Screening fasting plasma glucose (FPG) 300 mg/dL or greater or symptoms of hyperglycemia (polyuria, polydipsia); screening FPG < 60 mg dL, or a history of symptomatic hypoglycemia averaging more than once per day; or any other history suggestive of erratic glucose control
Screening fasting triglycerides 500 mg/dL or greater; or LDL-cholesterol 200 mg/dL or greater; screening blood pressure averaging 180 mm Hg or greater systolic or 100 mm Hg or greater diastolic
Subjects currently engaged in any regimented exercise program outside of the usual activities of daily living that is intended to achieve metabolic changes (e.g., weight loss, athletic training, etc.); any such activities occurring on a sporadic basis may still disqualify the subject, depending upon its frequency, to be judged at the discretion of the PI. Subjects must maintain their usual occupational and other routine daily activities during the study at a reasonably constant level.
Subjects who routinely engage in DDR, either at home or video game arcades; "occasional" participation in DDR may still disqualify the subject, depending upon the frequency of participation, to be judged at the discretion of the PI
Changing doses of any concurrent medications that are known to alter the study's outcomes (e.g., oral anti-hyperglycemic agents, lipid-lowering agents, weight loss agents, anti-hypertensive agents, systemic glucocorticoids, thyroid medications, hormone replacement therapies, oral contraceptives, etc.) or the anticipated need to start any of these medications; such medications taken concurrently must remain at constant dosages throughout the study.
Past history of clinically significant dysfunction of other organ systems (e.g., known hepatic disease or hepatic transaminase levels greater than 3X the upper limit of the normal range other than steatohepatitis; known renal dysfunction or creatinine level 1.5 mg/dL or greater; past history of malignancies excluding cutaneous basal cell carcinoma; known chronic infections including HIV, endocrinopathies such as untreated thyroid disease, adrenal disease, or pituitary dysfunction, etc.), or any recent surgeries that preclude regular exercise, in the opinion of the investigators
Active hemolytic anemia, known hemoglobinopathies, or any other state of accelerated RBC turnover that may alter the accuracy of the HbA1c measurement
Pregnancy or lactation
