The aim of this study was to examine the influence of skeletal muscle architecture (SMA) features measured by 2-D ultrasonography on jumping performance in humans. A systematic review and meta-analysis was conducted, registry number: CRD42016043602. The scientific literature was systematically searched in eight databases, last run on March 14th, 2017. Cross-sectional studies focused on the association between SMA features and vertical jumping performance were selected. A random-effects model was used to analyze the influence of lower-limb SMA and maximal jump height. A total of 11 studies were included in the qualitative synthesis and 6 studies were selected for meta-analysis. 250 correlations were reviewed across studies. The vast majority were either not statistically significant (185; 74%), weak or very weak (169; 68%) for different jump modalities; counter-movement jump (CMJ), squat jump (SJ), and drop jump. There was insufficient data to perform meta-analysis on muscles other than vastus lateralis for CMJ and SJ. The meta-analyses did not yield any significant association between vastus lateralis SMA and SJ height. Only a significant overall association was shown between vastus lateralis thickness and CMJ height (summary-r = 0.28; 95% confidence interval (CI) = -0.05 to 0.48; p = .059) for a 90% CI level. No differences were found between summary-r coefficients for SMA parameters and jump height during both jumps (CMJ: χ = 2.43; df = 2; p = .30; SJ: χ = 0.45; df = 2; p = .80) with a low heterogeneity ratio. Current evidence does not suggest a great influence of lower-limb SMA on vertical jumping performance in humans.
本研究旨在探讨二维超声测量的骨骼肌结构（SMA）特征对人类跳跃性能的影响。进行了一项系统评价和荟萃分析，注册号：CRD42016043602。于2017年3月14日在八个数据库中系统检索科学文献。选取了关注SMA特征与垂直跳跃性能之间关联的横断面研究。采用随机效应模型分析下肢SMA和最大跳跃高度的影响。定性综合分析共纳入11项研究，6项研究被选入荟萃分析。各研究共审查了250个相关性。对于不同的跳跃方式，即反向移动跳（CMJ）、深蹲跳（SJ）和跳深，绝大多数相关性在统计学上不显著（185个；74%），呈弱或极弱相关（169个；68%）。对于CMJ和SJ，除股外侧肌外，其他肌肉的数据不足以进行荟萃分析。荟萃分析未发现股外侧肌SMA与SJ高度之间存在任何显著关联。对于90%的置信区间水平，仅显示股外侧肌厚度与CMJ高度之间存在显著的总体关联（汇总相关系数r = 0.28；95%置信区间（CI）= -0.05至0.48；p = 0.059）。两种跳跃（CMJ：χ = 2.43；自由度df = 2；p = 0.30；SJ：χ = 0.45；自由度df = 2；p = 0.80）期间，SMA参数的汇总相关系数与跳跃高度之间未发现差异，异质性比率较低。目前的证据并不表明下肢SMA对人类垂直跳跃性能有很大影响。
