Abstract：
UNASSIGNED: This meta-analysis aims to systematically evaluate the impact of blood flow restriction training (BFRT) on muscle activation and post-activation potentiation (PAP) in the upper limbs, to provide guidance for upper limb protocols aiming to enhance explosive strength and activation.
UNASSIGNED: PubMed, CNKI, Web of Science, and EBSCO databases were queried to identify randomized controlled trials (RCTs) investigating the effects of upper limb BFRT on muscle activation and PAP. Inclusion and exclusion criteria were applied using the Cochrane bias risk tool. Literature quality assessment and statistical analysis were conducted using Revman 5.4 and Stata 17.0 software. Sensitivity analysis and funnel plots were utilized to assess result stability and publication bias.
UNASSIGNED: A total of 31 articles involving 484 participants were included in the analysis. Meta-analysis results showed that upper limb BFRT significantly increased muscle iEMG values [SMD = 0.89, 95%CI (0.21, 1.58), p = 0.01]. BFRT had a significant effect on upper limb explosive force [SMD = 0.73, 95%CI (0.41, 1.04), p < 0.00001]. Subgroup analysis based on literature heterogeneity (I 2 = 92%, 80%) showed that exhaustive BFRT significantly decreased upper limb iEMG [SMD = -0.67, 95%CI (-1.25, -0.09), p = 0.01], with exercise modes including maximum output power of bench press [SMD = 1.87, 95%CI (0.22, 3.53), p < 0.0001], exercise intensity of 40%-70% 1RM [SMD = 1.31, 95%CI (0.61, 2.01), p < 0.0001], and pressure intensity of ≥60% AOP [SMD = 0.83, 95%CI (0.43, 1.23), p < 0.0001] reaching maximum effects and statistical significance.
UNASSIGNED: Upper limb BFRT can induce muscle activation and PAP. BFRT with 40%-70% 1RM and ≥60% AOP in the upper limbs is more likely to promote PAP.

摘要：
■这项荟萃分析旨在系统地评估血流限制训练（BFRT）对上肢肌肉激活和激活后增强（PAP）的影响，为旨在增强爆发力和激活的上肢方案提供指导。
■PubMed,CNKI,WebofScience,和EBSCO数据库被查询以确定研究上肢BFRT对肌肉激活和PAP的影响的随机对照试验(RCT)。使用Cochrane偏倚风险工具应用纳入和排除标准。采用Revman5.4和Stata17.0软件进行文献质量评价和统计分析。使用敏感性分析和漏斗图评估结果稳定性和发表偏倚。
■总共31篇涉及484名参与者的文章被纳入分析。Meta分析结果显示上肢BFRT显著增加肌肉iEMG值[SMD=0.89,95CI(0.21,1.58),p=0.01]。BFRT对上肢爆发力有显著影响[SMD=0.73,95CI(0.41,1.04),p<0.00001]。基于文献异质性的亚组分析(I2=92%，80％）显示力竭BFRT显着降低上肢iEMG[SMD=-0.67，95CI（-1.25，-0.09），p=0.01],运动模式包括最大输出功率的台式压力机[SMD=1.87,95CI(0.22,3.53),p<0.0001],运动强度为40%-70%1RM[SMD=1.31，95CI（0.61，2.01），p<0.0001],和压力强度≥60%AOP[SMD=0.83，95CI（0.43，1.23），p<0.0001]达到最大效果和统计学意义。
■上肢BFRT可诱导肌肉激活和PAP。上肢有40%-70%1RM和≥60%AOP的BFRT更有可能促进PAP。
