Although compression garments are used to improve sports performance, methodological approaches and the direction of evidence regarding garments for use in high-intensity exercise settings are diverse.
Our primary aim was to summarize the association between lower-limb compression garments (LLCGs) and changes in sports performance during high-intensity exercise. We also aimed to summarize evidence about the following physiological parameters related to sports performance: vertical jump height (VJ), maximal oxygen uptake (VOmax), submaximal oxygen uptake (VOsubmax), blood lactate concentrations ([La]), and ratings of perceived exertion (RPE, 6-20 Borg scale).
We searched electronic databases (PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov) and reference lists for previous reviews. Eligible studies included randomized controlled trials with athletes or physically active subjects (≥ 18 years) using any type of LLCG during high-intensity exercise. The results were described as weighted mean difference (WMD) with a 95% confidence interval (95% CI).
The 23 included studies showed low statistical heterogeneity for the pooled outcomes. We found that LLCGs yielded similar running performance to controls (50-400 m: WMD 0.06 s [95% CI - 1.99 to 2.11]; 800-3000 m: WMD 6.10 s [95% CI - 7.23 to 19.43]; > 5000 m: WMD 1.01 s [95% CI - 84.80 to 86.82]). Likewise, we found no evidence that LLCGs were superior in secondary outcomes (VJ: WMD 2.25 cm [95% CI - 2.51 to 7.02]; VOmax: WMD 0.24 mL.kg.min [95% CI - 1.48 to 1.95]; VOsubmax: WMD - 0.26 mL.kg.min [95% CI - 2.66 to 2.14]; [La]: WMD 0.19 mmol/L [95% CI - 0.22 to 0.60]; RPE: WMD - 0.20 points [95% CI - 0.48 to 0.08]).
LLCGs were not associated with improved performance in VJ, VOmax, VOsubmax, [La], or RPE during high-intensity exercise. Such evidence should be taken into account when considering using LLCGs to enhance running performance.
尽管压缩服装被用于提高运动表现，但在高强度运动环境中使用服装的方法和证据方向却多种多样。
我们的主要目的是总结下肢压缩服装（LLCGs）与高强度运动中运动表现变化之间的关联。我们还旨在总结与运动表现相关的以下生理参数的证据：垂直跳跃高度（VJ）、最大摄氧量（VOmax）、次最大摄氧量（VOsubmax）、血乳酸浓度（[La]）和感知用力程度（RPE，6-20 倍 Borg 量表）。
我们检索了电子数据库（PubMed、EMBASE、Cochrane 图书馆和 ClinicalTrials.gov）和以前综述的参考文献列表。纳入的研究包括使用任何类型的 LLCG 进行高强度运动的随机对照试验，研究对象为运动员或体力活动者（≥18 岁）。结果以加权均数差（WMD）和 95%置信区间（95%CI）表示。
23 项纳入研究对汇总结果的统计学异质性较低。我们发现，LLCGs 与对照组相比，跑步表现相似（50-400m：WMD 0.06s[95%CI-1.99 至 2.11]；800-3000m：WMD 6.10s[95%CI-7.23 至 19.43]；>5000m：WMD 1.01s[95%CI-84.80 至 86.82]）。同样，我们没有发现 LLCGs 在次要结局方面具有优势的证据（VJ：WMD 2.25cm[95%CI-2.51 至 7.02]；VOmax：WMD 0.24mL.kg.min[95%CI-1.48 至 1.95]；VOsubmax：WMD-0.26mL.kg.min[95%CI-2.66 至 2.14]；[La]：WMD 0.19mmol/L[95%CI-0.22 至 0.60]；RPE：WMD-0.20 点[95%CI-0.48 至 0.08]）。
LLCGs 与高强度运动中 VJ、VOmax、VOsubmax、[La]或 RPE 的表现改善无关。在考虑使用 LLCGs 来提高跑步表现时，应考虑到这些证据。
