          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.

          Resistance exercise for muscular strength in older adults: a meta-analysis.

          The effectiveness of resistance exercise for strength improvement among aging persons is inconsistent across investigations, and there is a lack of research synthesis for multiple strength outcomes. The systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. A meta-analysis was conducted to determine the effect of resistance exercise (RE) for multiple strength outcomes in aging adults. Randomized-controlled trials and randomized or non-randomized studies among adults > or = 50 years, were included. Data were pooled using random-effect models. Outcomes for 4 common strength tests were analyzed for main effects. Heterogeneity between studies was assessed using the Cochran Q and I(2) statistics, and publication bias was evaluated through physical inspection of funnel plots as well as formal rank-correlation statistics. A linear mixed model regression was incorporated to examine differences between outcomes, as well as potential study-level predictor variables. Forty-seven studies were included, representing 1079 participants. A positive effect for each of the strength outcomes was determined however there was heterogeneity between studies. Regression revealed that higher intensity training was associated with greater improvement. Strength increases ranged from 9.8 to 31.6 kg, and percent changes were 29+/-2, 24+/-2, 33+/-3, and 25+/-2, respectively for leg press, chest press, knee extension, and lat pull. RE is effective for improving strength among older adults, particularly with higher intensity training. Findings therefore suggest that RE may be considered a viable strategy to prevent generalized muscular weakness associated with aging. 2010 Elsevier Ireland Ltd. All rights reserved.

              Physical activity levels in patients on hemodialysis and healthy sedentary controls.

              Patients on dialysis have reduced exercise tolerance compared with age-matched sedentary controls. The reasons for this debility have not been fully elucidated, but physical inactivity could be a contributing factor. The purpose of the current study was to determine whether patients on hemodialysis are less active than healthy sedentary controls and to explore clinical correlates of physical activity level in a group of hemodialysis patients. Thirty-four hemodialysis patients and 80 healthy sedentary individuals participated in the study. Physical activity was measured for seven days with a three-dimensional accelerometer and with an activity questionnaire. Vector magnitude values from the accelerometer for the dialysis and control subjects were 104,718 +/- 9631 and 161,255 +/- 6792 arbitrary units per day, respectively (P < 0.0001, mean +/- SEM). The estimated energy expenditure values derived from the questionnaire were 33.6 +/- 0.5 kcal/kg/day and 36.2 +/- 0.5 kcal/kg/day (P = 0.002). The difference between patients on dialysis and controls increased with advancing age. Among the dialysis subjects, some measures of nutritional status correlated with physical activity level, including serum albumin concentration (r = 0.58, P = 0.003), serum creatinine concentration (r = 0.37, P = 0. 03), and phase angle derived from bioelectrical impedance analysis (r = 0.40, P = 0.02). Patients on hemodialysis are less active than healthy sedentary controls, and this difference is more pronounced among older individuals. There is an association between the level of physical activity and nutritional status among patients on dialysis. These findings are of great concern, given the trend toward increasing age in incident dialysis patients and the well-known association between inactivity and increased mortality in the general population.
