The relationship between excess abdominal adipose tissue, metabolic and cardiovascular health risk has stimulated interest in the efficacy of physical activity in specifically perturbing this adipose depot. The evolution of imaging techniques has enabled more direct measurement of changes in abdominal and visceral fat. The purpose of this summary was to systematically review the relationship between physical activity and abdominal fat.
Database searches were performed on MEDLINE, CINAHL, SPORT DISCUS and PUBMED, from 1985 to 2005 with keywords "exercise", "abdominal fat" and "visceral fat".
Nineteen randomized controlled trials (RCTs) and eight non-randomized controlled trials were selected. In RCTs using imaging techniques to measure change in abdominal fat in overweight or obese subjects, seven out of 10 studies (including three trials with type 2 diabetics) reported significant reductions compared with controls. Reductions in visceral and total abdominal fat may occur in the absence of changes in body mass and waist circumference. Waist-to-hip ratio is not a sensitive measure of change in regional adiposity in exercise studies. No studies fulfil the Consolidated Standards of Reporting Trials (CONSORT) statement's criteria for the highest quality of randomized trial; however, many studies were in progress or published before the opportunity to comply with these recommendations. Therefore, limited evidence from a number of studies suggests a beneficial influence of physical activity on reduction in abdominal and visceral fat in overweight and obese subjects when imaging techniques are used to quantify changes in abdominal adiposity. More rigorous studies are needed to confirm these observations.
腹部脂肪过多与代谢及心血管健康风险之间的关系激发了人们对体育活动在专门扰动该脂肪库方面功效的兴趣。成像技术的发展使得更直接地测量腹部和内脏脂肪的变化成为可能。本综述的目的是系统评价体育活动与腹部脂肪之间的关系。
对1985年至2005年期间的MEDLINE、CINAHL、SPORT DISCUS和PUBMED数据库进行检索，关键词为“运动”、“腹部脂肪”和“内脏脂肪”。
选取了19项随机对照试验（RCT）和8项非随机对照试验。在使用成像技术测量超重或肥胖受试者腹部脂肪变化的RCT中，10项研究中有7项（包括3项2型糖尿病患者试验）报告与对照组相比有显著减少。在体重和腰围无变化的情况下，内脏和腹部总脂肪可能会减少。在运动研究中，腰臀比不是区域肥胖变化的敏感测量指标。没有研究符合报告试验的统一标准（CONSORT）声明中关于最高质量随机试验的标准；然而，许多研究是在有机会遵守这些建议之前进行或发表的。因此，一些研究的有限证据表明，当使用成像技术量化腹部肥胖变化时，体育活动对超重和肥胖受试者减少腹部和内脏脂肪有有益影响。需要更严格的研究来证实这些观察结果。
