单双侧训练对人体下肢爆发力影响的Meta分析

A Meta-analysis of the Effect of Unilateral and Bilateral Training on the Explosive Power of Human Lower Limbs

目的:采用Meta分析评价单、双侧训练对运动员下肢爆发力的影响,促进运动员素质的提升,为备战2024年巴黎奥运会提供参考。研究方法:搜索中国知网、Pumbed等平台的文献。对所搜集到的文献进行筛选和分析,同时采用stata16.0软件对筛选后的文献质量和数量进行分析。采用Revman 5.3进行数据统计,共16篇文献被纳入到研究统计中。Meta分析结果:(1)单、双侧训练对于运动员的下肢双侧CMJ的I~2=74%,95%CI线与无效线相交,不具备统计意义,单双侧训练对于运动员下肢双侧爆发力影响不显著。(2)单双侧训练对运动员下肢单侧CMJ的研究显示:I~2=0%,[SMD=1.65.95%CI(1.13,2.17),P=0.59>0.05],在统计学上具有意义,同时表明单双侧训练对运动员单侧下肢爆发力的提升具有非常显著的效果。研究结论:单双侧训练对于运动员单侧CMJ的提高具有显著的影响作用,但对于双侧CMJ的影响作用较小。本文纳入分析文献的运动项目大多都为单侧发力的项目,因此对于双侧训练对于运动员的下肢单侧爆发力还需要进一步探索。

The objective of this paper is to evaluate the effects of unilateral and bilateral training on athletes lower limb explosive power by means of meta-analysis,and to provide an important theoretical basis for improving athletes'quality and preparing for 2024 Paris Olympic Games.Research methods:CNKI,Pumbed and other literature search platforms.The collected literature was selected and analyzed,and the quality and quantity of the selected literature were analyzed by statal6.0 software.This paper uses Revman 5.3 for data statistics.A total of 16 articles were included in the study.The meta-analysis showed that:(a)The I2 of the bilateral CMJ of the lower limbs of the athletes was 74%,and the 95%CI line intersected with the invalid line,which did not have statistical significance.The impact of the unilateral and bilateral training on the explosive power of the lower limbs of the athletes was not significant.(b)The study of unilateral and bilateral training on the unilateral CMJ of athletes lower limbs shows that I?=0%,[SMD=1.65.95%CI(1.13,2.17),P=0.59>0.05],which is statistically significant,and also indicates that unilateral and bilateral training has a very significant effect on the improvement of explosive power of athletes unilateral lower limbs.Conclusion:According to the meta-analysis,unilateral and bilateral training has a significant effect on the improvement of unilateral CMJ of athletes,but has a small effect on bilateral CMJ.However,most of the sports included in the results of this paper are one-sided power events,so it is still necessary to further explore the impact of bilateral training on the unilateral explosive power of athletes*lower limbs.
