Excessive visceral adipose tissue appears to trigger a cascade of metabolic disturbances that seem to coexist with ectopic fat storage in muscle, liver, heart and the ß-cell. Therefore, the reduction of visceral adipose tissue potentially plays a pivotal role in the treatment of the metabolic syndrome. The purpose of this systematic review and meta-analysis is to describe the overall effect of exercise on visceral adipose tissue and to provide an overview of the effect of different exercise regimes, without caloric restriction, on visceral adipose tissue in obese persons. A systematic literature search was performed according to the PRISMA statement for reporting systematic reviews and meta-analyses. The initial search resulted in 87 articles after removing duplicates. After screening on title, abstract and full-text 15 articles (totalling 852 subjects) fulfilled the a priori inclusion criteria. The quality of each eligible study was assessed in duplicate with "The Critical Review Form for Quantitative Studies". Using random-effects weights, the standardized mean difference (Hedge's g) of the change in visceral adipose tissue was -0.497 with a 95% confidence interval of -0.655 to -0.340. The Z-value was -6.183 and the p-value (two tailed) was <0.001. A subgroup analysis was performed based on gender, type of training and intensity. Aerobic training of moderate or high intensity has the highest potential to reduce visceral adipose tissue in overweight males and females. These results suggest that an aerobic exercise program, without hypocaloric diet, can show beneficial effects to reduce visceral adipose tissue with more than 30 cm(2) (on CT analysis) in women and more than 40 cm(2) in men, even after 12 weeks.
过多的内脏脂肪组织似乎会引发一连串的代谢紊乱，这些紊乱似乎与肌肉、肝脏、心脏和β细胞中的异位脂肪储存并存。因此，减少内脏脂肪组织可能在代谢综合征的治疗中起着关键作用。本系统评价和荟萃分析的目的是描述运动对内脏脂肪组织的总体影响，并提供一个不限制热量的不同运动方案对肥胖者内脏脂肪组织影响的概述。根据系统评价和荟萃分析报告的 PRISMA 声明进行了系统的文献检索。初始搜索在去除重复项后得到 87 篇文章。经过标题、摘要和全文筛选，有 15 篇文章（共计 852 名受试者）符合预先确定的纳入标准。使用随机效应权重，内脏脂肪组织变化的标准化均数差（Hedge's g）为-0.497，95%置信区间为-0.655 至-0.340。Z 值为-6.183，p 值（双侧）<0.001。根据性别、训练类型和强度进行了亚组分析。中等或高强度的有氧运动最有可能减少超重男性和女性的内脏脂肪组织。这些结果表明，在不进行低热量饮食的情况下，有氧运动方案可以显示出有益的效果，可减少女性 CT 分析超过 30 cm²（超过 30 cm²）和男性超过 40 cm²（超过 40 cm²）的内脏脂肪组织，即使在 12 周后也是如此。
