Table_1_Pilates for Overweight or Obesity: A Meta-Analysis.doc

Background: Evidence for the efficacy of Pilates for the modulation of body weight and body composition is unclear.
Objective: This meta-analysis aimed to evaluate the effects of Pilates on body weight and body composition in adults with overweight or obesity.
Data Sources: The PubMed, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), and EMBASE databases were systematically searched from the inception dates to 12 November 2020 for relevant randomized controlled trials (RCTs).
Study Selection: Randomized controlled trials comparing Pilates with other physical exercises or without any intervention were included.
Data Extraction and Synthesis: Three reviewers independently performed the data extraction and assessed study quality. The mean differences (MDs) and 95% confidence intervals (CIs) for pooled data were calculated.
Main Outcomes and Measures: Outcome measures were body weight, body mass index (BMI), body fat percentage, lean body mass, and waist circumference.
Results: Eleven RCTs with 393 subjects were included. This study revealed that Pilates dramatically reduces body weight (MD = −2.40, 95% CI: [−4.04, −0.77], P = 0.004, I2 = 51%), BMI (MD = −1.17, 95% CI: [−1.85, −0.50], P = 0.0006, I2 = 61%), and body fat percentage (MD = −4.22, 95% CI: [−6.44, −2.01], P = 0.0002, I2 = 88%) in adults with overweight or obesity. The reduction in body weight and body fat percentage appears to be more pronounced in studies including participants with obesity only, and the efficacy of Pilates for the improvement of body weight and BMI appears to be more evident in longer intervention duration. However, Pilates has no significant effect on waist circumference (MD = −2.65, 95% CI: [−6.84, 1.55], P = 0.22, I2 = 0%) and lean body mass (MD = −0.00, 95% CI: [−1.40, 1.40], P = 1.00, I2 = 23%).
Conclusions: Pilates dramatically reduces body weight, BMI, and body fat percentage in adults with overweight or obesity. Large-scale and well-designed RCTs with improved methodology and reporting are urgently needed to further confirm these results.

研究背景：普拉提（Pilates）对体重与身体成分的调节功效相关证据尚不明确。
研究目的：本荟萃分析旨在评估普拉提对超重或肥胖成年人群体的体重及身体成分的影响。
数据来源：系统检索PubMed、考克兰图书馆（Cochrane Library）、Web of Science、中国知网（China National Knowledge Infrastructure, CNKI）及EMBASE数据库，检索时限为各数据库建库至2020年11月12日，以获取相关随机对照试验（randomized controlled trials, RCTs）。
研究筛选：纳入将普拉提与其他体育锻炼或无干预措施进行对比的随机对照试验。
数据提取与合成：由3名评价者独立完成数据提取及研究质量评估，对合并数据计算均数差（mean differences, MDs）及95%置信区间（confidence intervals, CIs）。
主要结局与指标：本研究的结局指标包括体重、体重指数（body mass index, BMI）、体脂百分比、瘦体重及腰围。
研究结果：共纳入11项随机对照试验，涉及393名受试者。本研究显示，普拉提可显著降低超重或肥胖成年人的体重（MD=-2.40，95%CI：[-4.04, -0.77]，P=0.004，I²=51%）、体重指数（BMI=-1.17，95%CI：[-1.85, -0.50]，P=0.0006，I²=61%）及体脂百分比（MD=-4.22，95%CI：[-6.44, -2.01]，P=0.0002，I²=88%）。仅纳入肥胖受试者的研究中，体重及体脂百分比的降低效果更为显著；干预时长更长的研究中，普拉提改善体重及BMI的效应更为明确。但普拉提对腰围（MD=-2.65，95%CI：[-6.84, 1.55]，P=0.22，I²=0%）及瘦体重（MD=-0.00，95%CI：[-1.40, 1.40]，P=1.00，I²=23%）无显著影响。
研究结论：普拉提可显著降低超重或肥胖成年人的体重、BMI及体脂百分比。未来亟需开展方法学及报告规范更完善的大规模高质量随机对照试验，以进一步验证本研究结果。
