摘要:

文题释义:
离心训练:是一种使肌肉对抗适宜离心负荷进行收缩的训练方法,相较于等长和向心收缩模式能更加提高神经肌肉系统活性,从而提高肌肉力量和功能。
离心收缩峰力矩:是利用等速肌力测试仪器计算出肌肉在某一测试角度下进行离心收缩的最大力矩值,反映了肌肉在离心收缩过程中的最大力量。

目的:离心训练改善腘绳肌肌力的评价指标较为分散,研究结果并不一致。文章运用Meta分析研究离心训练对腘绳肌肌力的影响,旨在为提高运动训练效果及应用合理有效的损伤防护策略提供循证依据。
方法:检索中国知网、万方数据库、PubMed、Web of Science、EBSCO等数据库中关于离心训练改善腘绳肌肌力的随机对照试验,检索时限为建库至2021年9月。运用Review manager 5.3和Stata 16.0软件对纳入文献进行质量评价、Meta分析、亚组分析、敏感性分析及发表偏倚分析。
结果:①纳入14篇文献,共有557名试验对象,其中试验组314人、对照组243人,文献整体质量较高。②离心训练可以作为有效的干预手段,能够显著提高腘绳肌向心收缩相对峰力矩(SMD=0.60,95%CI:0.18-1.02,P < 0.01)和离心收缩峰力矩(SMD=0.43,95%CI:0.18-0.67,P < 0.001),明显改善功能H/Q比率(SMD=0.69,95%CI:0.34-1.05,P=0.000 1),对等长收缩峰力矩和传统H/Q比率无显著作用效果。③选用低角速度测试时,试验组向心收缩相对峰力矩(SMD=0.86,95%CI:0.22-1.49,P < 0.01)和离心收缩相对峰力矩(SMD=0.46,95%CI:0.09-0.82,P < 0.05)与对照组之间的差异均存在显著性意义。④6周离心训练对功能H/Q比率的提升效果明显优于4周和27周(SMD=0.71,95%CI:0.32-1.10,P < 0.001)。
结论:离心训练可以作为一种力量提升手段提高腘绳肌肌力,具体表现为提高腘绳肌向心和离心收缩力量,纠正腘绳肌与股四头肌肌力不均衡,为降低腘绳肌初次或再次损伤的发生提供可能性。

Abstract: OBJECTIVE: The evaluation indexes for hamstring strength improved by eccentric strengthening are scattered and the results are not consistent. Herein, a Meta-analysis is conducted to analyze the influence of eccentric training on hamstring strength, aiming to provide an evidence-based basis for improving the effect of sports training and applying reasonable and effective strategies for injury protection.
METHODS: Randomized controlled trials on hamstring strength improved by eccentric strengthening were searched from CNKI, WanFang, PubMed, Web of Science, and EBSCO databases. The retrieval period was from database building to September 2021. Review manager 5.3 and Stata 16.0 were used for quality assessment, Meta-analysis, subgroup analysis, sensitivity analysis, and publication bias analysis.
RESULTS: A total of 14 articles involving 557 subjects were included, with 314 subjects in experimental group and 243 subjects in control group. The overall quality of literature was high. Eccentric strengthening can be used as an effective intervention to significantly improve the relative concentric contraction peak torque [standardized mean difference (SMD)=0.60, 95% confidence interval (CI): 0.18-1.02, P < 0.01] and eccentric contraction peak torque of the hamstrings (SMD=0.43, 95% CI: 0.18-0.67, P < 0.001) and functional H/Q ratio (SMD=0.69, 95% CI: 0.34-1.05, P=0.000 1), but it has no significant effect on isometric contraction peak torque and conventional H/Q ratio. The relative concentric contraction peak torque (SMD=0.86, 95% CI: 0.22-1.49, P < 0.01) and the relative eccentric contraction peak torque (SMD=0.46, 95% CI: 0.09-0.82, P < 0.05) in the experimental group were significantly different from those in the control group when a low angular velocity was selected. The 6-week eccentric strengthening was better than the 4- and 27-week eccentric strengthening to improve the functional H/Q ratio (SMD=0.71, 95% CI: 0.32-1.10, P < 0.001).
CONCLUSION: Eccentric strengthening can improve hamstring strength, characterized by increasing hamstring concentric and eccentric contraction strength, correcting the strength imbalance of hamstring and quadriceps, and reducing initial or second injuries of the hamstring.
