OBJECTIVES: Combined aerobic and resistance exercise (CARE) is beneficial for improving renal function. To confirm this, we conducted a meta-analysis to evaluate the effects of CARE on renal function in adult patients with chronic kidney disease (CKD). DATE SOURCES: The last date of search was 22 February 2020. We searched Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, Allied and Complementary Medicine (AMED), CINAHL, Web of Science, SPORTDiscus, and three Chinese databases (China National Knowledge Infrastructure (CNKI), Wanfang, Journal Integration Platform (VIP)) for articles of randomized and quasi-randomized controlled trials. METHODS: We used the Cochrane tool and the JBI Critical Appraisal checklist to assess randomized controlled trials and quasi-randomized controlled trials, respectively. RESULT: A total of 12 studies and 745 patients were included. Compared with usual care or no exercise, CARE resulted in a significant improvement in the estimated glomerular filtration rate (between-group analysis mean difference (MD) 5.01, 95% confidence interval (CI) 2.37 to 7.65; within-group analysis MD 3.01, 95% CI 0.86 to 5.16). The serum creatinine levels also showed a significant improvement after CARE (between-group analysis MD -8.57, 95% CI -13.71 to -3.43; within-group analysis MD -6.33, 95% CI -10.23 to -2.44). Patients who performed CARE also demonstrated a decline in the blood pressure in the within-group analysis (systolic blood pressure MD -5.24, 95% CI -7.93 to -2.54; diastolic blood pressure MD -3.63, 95% CI -5.35 to -1.91). However, there were no significant differences in proteinuria, lipid levels, physical composition, and quality of life. CONCLUSION: The study results support the concept that CARE intervention improves renal function. It provides strong evidence for guiding clinical decisions and implementing renal rehabilitation exercises.
