tionally defined?
             The independent variable is conceptually defined as obese coronary patients. A operationally definition of the independent variable would be "116 obese (body mass index [BMI] more than equals 27.8 kg/m2 for men and more than equals 27.3 kg/m2 for women; mean, 31.2 plus minus 3.2 kg/m2] and 198 (mean BMI, 24.6 plus minus 2.1 kg/m2) non-obese patients with recent cardiac events." (Lavie CJ, 1996) The dependant variable is conceptually defined as "Modest reductions in BMI, obesity, and severe obesity occur after cardiac rehabilitation. In addition, obese patients demonstrate significant improvements in most coronary risk factors after rehabilitation, although improvements in exercise capacity are greater in non-obese patients." (Lavie CJ, 1996) The defined operational variable is "
             Review of Literature and/or Conceptual Framework:
             1. What are the topics included in the review of literature
             The following section of the article reviews the literature cited: Cardiac rehabilitation and exercise training have been proven to have beneficial effects on CHD risk factors, including improving plasma lipids, insulin sensitivity, obesity indices, and exercise capacity and favorably affecting psychosocial function, behavioral characteristics, and overall quality of life. [15-19] Recent studies also have indicated significant effects of cardiac rehabilitation on reducing subsequent hospitalization costs following major CHD events, [20] and pooled data from several randomized studies indicate significant reductions in subsequent major CHD events, cardiac mortality, and all-cause mortality. [21,22] However, the effects of cardiac rehabilitation and exercise training in obese patients with CHD have not been well studied.
