Scopus, CINAHL, PubMed, Science Direct, Cochrane Library, and reference lists were searched. Experimental studies that investigated the effect of arm exercise before and post-operation on AVF maturations were included. Screened and extracted data were administered by two independent reviewers. Seven studies with preoperative exercise were included in a systematic review, while five studies were analyzed in a meta-analysis. Preoperative exercise significantly increased vessel diameters and grip strength after training. Postoperative exercise had higher clinical and ultrasonographic (US) maturation rates and arterial blood flow than controls (risk ratio [RR], 1.44; 95% confidence interval [CI], 1.23–1.69; RR, 1.27; 95% CI, 1.02–1.57; weight mean difference, 166.03; 95% CI, 27.58–304.49, respectively). Subgroup analysis showed that isometric exercise training promoted clinical and US maturations (RR, 2.40; 95% CI, 1.51–3.82; RR, 1.53; 95% CI, 1.02–2.30, respectively), whereas isotonic exercise promoted clinical maturation (RR, 1.18; 95% CI, 1.03–1.34). Grip strength had a greater trend in the intervention group than controls (standardized mean difference, 0.59; 95% CI, −0.06 to 1.25). In conclusion, arm exercise training improves vascular function, which is essential before surgery. The meta-analysis suggested that arm exercise training promotes AVF clinical and US maturations after surgery. Subgroup analysis suggested that isometric-arm exercise training may have a larger effect on AVF maturation. However, more studies are needed to draw a solid conclusion.
