Purpose:

This study investigates the degree of improvement in insulin resistance and features of the metabolic syndrome in non-diabetic overweight or obese subjects after training in a low-intensity, moderate-intensity or non-aerobic exercise program, as well as self-initiated exercise behavior after the assigned exercise program.


Study summary:

The proposed study is a randomized, open study comparing low-intensity and moderate-intensity aerobic exercise versus non-aerobic (stretching) exercise on direct measurements of insulin resistance and variables associated with the metabolic syndrome. This 6-month intervention will be followed by an additional 6-month follow-up period during which subjects will be encouraged to maintain their exercise regimen (along with their prescribed diet) but without scheduled supervision. Behavioral variables associated with adherence will be analyzed along with changes in the above physiological variables.


Criteria:

Inclusion Criteria: - Males or females, age 18-60 - At least 2 of the 5 components of the NCEP definition of the metabolic syndrome, provided that either the triglyceride or waist circumference criteria are met - Body mass index of 25-45 kg/m2 - Subjects not currently following a regular exercise program nor an optimal diet, and who self-report their activity level as sedentary - Able to understand and sign the informed consent form, follow the instructions given in the study, attend all necessary clinic visits, and undergo all required study procedures Exclusion Criteria: - Past or current diabetes mellitus - Significant concurrent medical illnesses (chronic liver or renal disease, malignancies, recent or chronic infections including HIV, surgeries or other hospitalizations within four weeks prior to screening), uncontrolled hypertension (BP >160/90 mm Hg), or abnormal TSH on screening. - Conditions that may contraindicate physical activity (clinically significant cardiac, pulmonary, orthopedic, rheumatological or neurological diseases) - Cardiovascular disease not controlled with medical therapy, or invasive vascular procedures within six months prior to screening - Subjects found on resting EKG or stress testing to have underlying cardiac abnormalities - Perimenopausal women who are experiencing irregular menses - Pregnant or lactating women - Subjects who may have limited exercise tolerance because of treatment with β-adrenergic blockade agents, at least until agents of alternate drug classes can be substituted - Subjects with concurrent endocrinopathies - Subjects receiving concurrent treatment with metformin, thiazolidinediones, systemic glucocorticoids, or any weight loss agents - Subjects who expect to require medications during the course of the study that may affect their metabolic profile, including systemic glucocorticoids and hormone replacement therapies - Subjects who cannot complete the stress test due to physical limitations - Any other factors that, in the opinion of the investigators, may interfere with the safe conduct, the successful completion, or the quality of the data obtained from the study
