Effects of intradialytic resistance exercises on physical performance, nutrient intake and quality of life among haemodialysis people: A systematic review and meta‐analysis

Abstract

Objectives The aim of this systematic reviews was to synthesize the current studies for the effectiveness of intradialytic resistance exercises with usual care on HD people. Design Meta‐analysis of randomized controlled studies. Methods A systematic search of seven electronic databases, including PubMed, EMBASE, the Cochrane Library, Web of Science, WanFang, China National Knowledge Infrastructure (CNKI) and SINOMED, was systematically searched up to May 2018. The reference lists of previously reported systematic review were also checked. Pooled analysis was used to determine effection of intradialytic resistance exercises for haemodialysis people. Physical performance, nutrient intake and quality of life were explored, by comparing the association between effect sizes. Results Fourteen studies of 594 people were included. Compared with control groups, intradialytic resistance exercises significantly improve physical performance included 6‐min walk test, sit‐to‐stand 30 and grip strength. However, no significant improvements were found in nutrient intakes such as dietary protein intake and quality of life.

Does Intradialytic Group Exercise Influence Malnutrition and Quality of Life in Maintenance Hemodialysis Patients? Evidence From an Experimental Study Using a Single-group Repeated-measures Design

“…Results also showed that the intradialytic group exercise could improve the QOL of MHD patients gradually. This nding was in consistence with what were found before [53][54][55][56]. Survival of MHD patients has been prolonged, but the improvement in quality of life has not keep in pace obviously [57].…”

Therapeutic effects of exercise interventions for patients with chronic kidney disease: an umbrella review of systematic reviews and meta-analyses

“…The search identified 2305 potential articles, of which 648 were duplicates. After reading the title and abstract, 1598 papers were excluded and 28 were excluded after full-text review resulting in 31 final studies 10 24–53. The PRISMA flow chart of study inclusion is illustrated in figure 1.…”

“…The effect of exercise on the 6 min walk test was investigated in 14 meta-analyses (reported in 13 articles) with a mild heterogeneity (average I 2 =44.9%),25 28–30 32 34 36–38 40 41 43 51 and 13 reported positive statistically significant outcomes 25 28–30 32 34 36–38 41 43 51. Of the 14 meta-analyses, 2 reported a small effect size,25 28 5 reported a moderate effect size36 37 41 43 51 and 3 reported a large effect size 32 34 38. GRADE assessment of quality indicated the overall evidence as being very low (eight meta-analyses25 30 32 34 38 40 43), low (four meta-analyses28 37 41 51) and moderate (two meta-analyses29 36).…”

The Effect of Exercise on Nutritional Status and Body Composition in Hemodialysis: A Systematic Review

“…A significant increase in pre-albumin was observed after resistance training compared to non-active patients [ 77 ]. Chan et al [ 78 ] and Zhang et al [ 79 ] found preliminary evidence that resistance training can reduce malnutrition and no significant improvement in nutrient intake, respectively.…”
