摘要

目的。特定运动减少局部脂肪组织储存(目标脂肪减少)和改变脂肪分布的过程通常被称为斑点减少。根据这一长期流行的观点,与对侧肢体相比,锻炼肢体会导致邻近脂肪组织减少更多。除了大众的智慧,20世纪和21世纪的科学证据似乎提供了不确定的结果。本研究的目的是总结同行评议的文献,评估单侧肢体训练与对侧肢体训练对健康参与者局部脂肪组织库的影响,并对其结果进行荟萃分析。方法。我们遵循系统评价和荟萃分析首选报告项目的指导方针。我们使用几个相关的关键字组合搜索PubMed、Web of Science和Scopus电子数据库。我们联系了独立专家,以帮助确定其他相关文章。根据PICOS方法,我们纳入了对照研究,这些研究将局部运动干预(即单腿训练)纳入健康参与者(即没有健身、年龄或性别限制)与对照条件(即对侧肢体)的队列,其中主要结果是局部脂肪的干预前后变化。采用物理治疗证据数据库量表评估研究的方法学质量。训练组和对照组(肢体)脂肪相关结局的干预前和干预后均值±标准差转换为Hedges效应量(ES;95%可信区间[CI])。采用i2统计量评估异质性的影响。扩展埃格的检验用于探索报告偏倚的风险。差异有统计学意义,p < 0.05。结果。从最初确定的1833份检索记录中,13份纳入meta分析,涉及1158名男性和女性参与者(年龄14-71岁)。这13项研究具有较高的方法学质量,结果异质性低(i2 = 24.3%),无偏倚(Egger’s检验p = 0.133)。荟萃分析涉及37个比较,其中17个倾向于训练肢体(即更大程度地减少局部脂肪),20个倾向于未训练肢体,但ES范围在-1.21至1.07之间。效果是一致的,合并ES = -0.03, 95% CI: -0.10至0.05,p = 0.508,意味着没有观察到斑点减少。结论。局部肌肉训练对局部脂肪组织储存没有影响,也就是说,无论人群的特征和运动计划如何,都没有斑点减少。关于减少现货的普遍看法可能源于一厢情愿的想法和便利的营销策略,例如网红寻求增加人气,程序卖家对增加广告感兴趣。局部脂肪(斑点a)

A proposed model to test the hypothesis of exerciseinduced localized fat reduction (spot reduction), including a systematic review with meta-analysis
Purpose. The process in which specific exercises reduce localized adipose tissue depots (targeted fat loss) and modify fat distribution is commonly termed spot reduction. According to this long-held popular belief, exercising a limb would lead to greater reduction in the adjacent adipose tissue in comparison with the contralateral limb. Aside from popular wisdom, scientific evidence from the 20 th and 21 st century seems to offer inconclusive results. The study aim was to summarize peer-reviewed literature assessing the effects of unilateral limb training, compared with the contralateral limb, on the localized adipose tissue depots in healthy participants, and to meta-analyse its results. Methods. We followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We searched PubMed, Web of Science, and Scopus electronic databases using several relevant keyword combinations. Independent experts were contacted to help identify additional relevant articles. Following the PICOS approach, we included controlled studies that incorporated a localized exercise intervention (i.e., single-leg training) to cohorts of healthy participants (i.e., no restriction for fitness, age, or sex) compared with a control condition (i.e., contralateral limb), where the main outcome was the pre-to-post-intervention change of localized fat. The methodological quality of the studies was assessed with the Physiotherapy Evidence Database scale. Pre- and post-intervention means ± standard deviations of the fat-related outcome in the trained and control groups (limbs) were converted to Hedges’ g effect size ( ES ; with 95% confidence intervals [CI]) by using a random-effects model. The impact of heterogeneity was assessed with the I 2 statistic. Extended Egger’s test served to explore the risk of reporting bias. The statistical significance threshold was set at p < 0.05. Results. From 1833 search records initially identified, 13 were included in the meta-analysis, involving 1158 male and female participants (age, 14–71 years).
