Review on Exercise Intervention Methods for Weight Loss in Obese Individuals

Abstract

PURPOSE The prevalence of obesity in South Korea has been greatly increased over the past decades despite increases in one’s participation in weight reduction programs including exercise intervention. While it has been repeatedly shown that exercise has positive impacts on many health outcomes including lean body mass, fat mass, and insulin sensitivity, its effect on weight reduction is largely unclear. The purpose of this review was to summarize available data on the effect of exercise intervention on weight reduction and provide guidelines for developing effective exercise intervention, applicable to clinical practice. METHODS In this review, we reviewed currently available data mainly from meta-analytic studies and other available literature on the effect of therapeutic exercise intervention on weight loss. RESULTS Studies have generally shown that exercise intervention alone may not be effective in weight reduction due in part to insufficient exercise volume, compensatory increases in food intake, and so on. CONCLUSIONS It seems that exercise, especially when combined with other interventions such as diet, may enhance effectiveness of the weight loss intervention through increases in lean body mass and/or decreases in fat mass in an exercise volume dependent manner. 색인어: 비만, 운동량, 운동강도, ìš´ë™ì¢ ë¥˜, 체중감량 Keywords: Obesity, Exercise volume, Exercise intensity, Exercise type, Weight loss
