ABSTRACT
Obesity is significantly correlated with prevalence of metabolic syndrome and is an important risk factor of mortality. However, overweight or slight obesity does not increase mortality; therefore, physical fitness might be a more important factor of mortality in such people. The main targets of exercise intervention programs for obesity treatment include decreases in waist circumference, visceral fat, and metabolic risk factors without weight change and improvement of cardiorespiratory function. Based on the results of this study, we suggest the importance of physical fitness for the prevention of obesity-related cardiovascular risk factors and the importance of body composition, body weight control, and lifestyle change for prevention of obesity-related metabolic risk factors.
