Abstract
PURPOSE Clinical guidelines call for the inclusion of exercise interventions in every patient's dialysis session, but these recommendations are rarely adopted. Healthcare providers play a key role in this. Therefore, the aim of this study was to explore how healthcare providers perceive the benefits, risks and barriers of intradialytic exercise (IDE). METHODS We conducted 21 individual, semi-structured interviews with 11 nurses, 5 nephrologists, 3 training assistants and 2 managers from two dialysis centres in Slovakia. Verbatim transcripts of digitally recorded interviews were thematically analysed using MAXQDA®. RESULTS Participants reported the benefits of IDE as improvements in patients' physical and psychosocial functioning, independence and self-efficacy, clinical profile and quality of therapy. As risks of IDE, they most frequently reported exercise-related damage to vascular access, insufficient individualization of training and musculoskeletal injuries. The presence of psychological problems among patients was reported as a major barrier for initiating and maintaining patients' exercise. Other reported barriers included limitations in financial and personnel resources of haemodialysis care. CONCLUSIONS Safe and sustainable implementation of IDE, which might improve a patient's well-being, need to be prescribed in alignment with the patient's clinical profile, be delivered individually according to the patient's characteristics and requires adjustments in the available resources.

Abstract
BACKGROUND The Low Physical Activity Questionnaire (LoPAQ) was specifically developed to measure the low activity level observed in extremely inactive hemodialysis (HD) patients. This study aims to evaluate reliability and validity of Persian version of the LoPAQ. METHODS This study was a cross sectional study, conducted in three HD centers in Iran. The LoPAQ was translated into Persian. After cultural adaptions, it was filled out by 120 HD patiens. Convergent validity, was evaluated by calculating the correlations among the Persian version of the LoPAQ and Persian version of the Community Healthy Adults Model Program for Seniors (CHAMPS) questionnaire, physical function scale of the SF-36 and physical function (Short Physical Performance Battery (SPPB) test) using Spearman's correlation coefficients. The test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). RESULTS In total, 109 patients completed all of the questionnaires, took part in physical performance tests and had valid data. Their mean age was 64 ± 11 years, with a dialysis history of 31 ± 10 months. For total calories, there was a strong correlation between the Persian version of the LoPAQ and CHAMPS-measured physical activity (rho = 0.85, p < 0.001). In addition, the higher physical activity level reported by Persian version of the LoPAQ was also correlated with better self-reported physical function (rho = 0.7, p < 0.001) and better physical performance (rho = 0.67, p < 0.001). The ICC ranged from 0.65 to 0.78, indicating strong reliability. CONCLUSION The assessment of the validity and reliability of the Persian version of the questionnaire confirmed its suitability for evaluating the level of physical activity.

Abstract
OBJECTIVE To investigate the effects of unilateral upper limbs' (ULM) neuromuscular electrical stimulation (NMES) superimposed on a voluntary contraction added to a protocol of intradialytic leg cycle ergometer exercise on muscle strength, functional capacity and quality of life of adult patients with chronic kidney disease (CKD). METHODS This randomized controlled clinical trial will be carried out at a Brazilian University Hospital. The patients will be evaluated and randomly allocated to an intervention group (i.e., unilateral NMES on the upper limb without hemodialysis fistula for 20 min and leg cycle ergometer for 30 min) or a control group (i.e., unilateral NMES-Sham on the upper limb without hemodialysis fistula for 20 min and leg cycle ergometer for 30 min). The patients will be treated for 8 weeks, with three weekly treatment sessions totaling 24 sessions. MEASUREMENTS ULM muscle strength, functional capacity, quality of life and also the feasibility, safety and patient adherence to the exercise protocol. All physical measurements will be collected by trained researchers before treatment (week 0) and at the end of treatment (week 9), always in the second hemodialysis session of the week. It will be used in an intention-to-treat analysis. RESULTS/CONCLUSIONS The outcomes of this clinical trial protocol may help to know the possible benefits of unilateral ULM' NMES superimposed on a voluntary contraction added to a protocol of leg cycle ergometer for patients with CKD and to aid clinical decisions about future implementation or not of this technique (NMES) in intradialytic physical training programs.

Abstract
Purpose of the review The purpose of the review is to discuss current proven benefits and problems of integrating exercise in the care of people receiving dialysis by reviewing literature from the last few years and identifying important questions that still need to be asked and answered. Methods A focused review and appraisal of the literature were done. Original peer-reviewed articles, review articles, opinion pieces and guidelines were identified from PubMed and Google Scholar databases. Only sources in English were accessed. Search terms "exercise" and "dialysis" were used to find active recruiting randomized trials in various clinical trial registry platforms. Key findings Numerous studies have demonstrated the benefits of exercise training in individuals receiving dialysis, limited by factors such as short duration of follow-up and inconsistent adverse event reporting and outcomes selected. Notable gaps in exercise research in dialysis include ways to maintain programs and patient motivation, studies in peritoneal dialysis and home hemodialysis patients, and how best to define and measure outcomes of interest. Implications This review summarizes the current state of exercise in people receiving dialysis and serves as a call to action to conduct large, randomized controlled trials to improve the quality of evidence needed to implement and sustain innovative, exercise interventions, and programs for this population.

Abstract
Chronic kidney disease and the need for kidney replacement therapy have increased dramatically in recent decades. Forecasts for the coming years predict an even greater increase, especially in low- and middle-income countries, due to the rise in metabolic and cardiovascular diseases and the aging population. Access to kidney replacement treatments may not be available to all patients, making it especially strategic to set up therapy programs that can ensure the best possible treatment for the greatest number of patients. The choice of the "ideal" kidney replacement therapy often conflicts with medical availability and the patient's tolerance. This paper discusses the pros and cons of various kidney replacement therapy options and their real-world applicability limits.

Abstract
BACKGROUND Patients with kidney failure have a high mortality rate. This study aimed to evaluate the effect of intradialytic exercise on survival in patients receiving hemodialysis (HD). METHODS In this randomized controlled trial conducted in a HD center in Iran, adult patients receiving chronic HD were randomized to intradialytic exercise (60 min) in the second hour of thrice weekly dialysis for 6 months (intervention) or no intradialytic exercise (control). The primary outcome was survival rate at 12 months. Secondary outcomes were serum albumin, hemoglobin, hematocrit, red blood cell count, serum calcium, serum phosphorous, parathyroid hormone, physical function (6-min walk test) and nutritional status (Geriatric Nutritional Risk Index) during the first 6 months. The trial follow-up period was 12 months. RESULTS The study included 74 participants (44 males) with an age average of 64 ± 12 years old and a dialysis history of 27 ± 12 months, randomized to intervention (n = 37) or control (n = 37). Compared with controls, 1-year survival was higher in the intervention group (94% vs 73%, P = 0.01). The hazard ratio in univariate analysis in intervention group was 0.17 (95% CI 0.04-0.8; P = 0.02) compared to that in control group. During the 6-month intervention period, significant between-group changes were observed in all secondary outcomes between the intervention and control groups. CONCLUSION Intradialytic exercise performed for at least 60 min during thrice weekly dialysis sessions improves survival in adult patients receiving HD.

Abstract
Chronic kidney disease (CKD) leads to gradual muscle mass loss, which is strongly associated with lower functional capacity, which limits a patient’s daily activities. The aim of the present study is to examine the effects of a 4-month intradialytic exercise program on the functional capacity and body composition of kidney transplant (KT) candidates. Twenty-nine male patients on hemodialysis (HD) waiting for a kidney transplant, with a mean age of 53.86 ± 9.56 years old and BMI 27.11 ± 5.55 kg/m2, were randomly assigned into the following two groups: A (nA = 15 HD patients), who followed a 4-month intradialytic exercise program combining aerobic and resistance training, with a supervised, progressively increasing workload, and B (nB = 14 HD patients), who continued to receive usual care. At baseline and the end of the study, the KT candidates underwent a 6-min walking distance (6-MWD), and a 10-repetition sit-to-stand test (10-STS) to access physical function, a handgrip strength (HGS) test to evaluate the muscle strength of the non-fistula hand. Moreover, the bioelectrical impedance analysis (BIA) was performed to assess body composition indices, such as body fat (BF), body fat mass index (BFMI), fat-free mass index (FFMI), body cell mass (BCM), basal metabolic rate (BMR), extracellular water (ECW), intracellular water (ICW), total body water (TBW) and phase angle (PhA). Following the exercise program, group A showed favorable improvements in HGS (from 26.59 ± 9.23 to 28.61 ± 9.58 kg, p < 0.05) and 6-MWD (from 427.07 ± 7.66 to 468.16 ± 11.39 m, p < 0.05). Intergroup results from 6-MWD showed a statistically significant difference (Δp = 0.04), at the end of the study. Moreover, group A results from BIA revealed a significant increase of BMR by 2.4% (p < 0.05), ECW by 3.6% (p = 0.01), ICW by 3.8% (p = 0.01), TBW by 4.1% (p = 0.01), lean mass by 2.7% (p = 0.01), and PhA by 13.3% (p = 0.04), while a reduction in BF by 5.0% (p = 0.01) and BFMI by 6.6% (p = 0.03) was also noticed. At the end of the study, group A showed statistical differences in BMR (Δp = 0.01), BMR/BW (Δp = 0.01), dry lean (Δp = 0.01), and PhA (Δp = 0.03), compared to the group B. Linear regression analysis in group A after training showed positive correlations between HGS and both PhA (r = 0.52, p = 0.04) and FFMI (r = 0.64, p = 0.01), and a strong negative correlation between 6-MWT and BF (r = −0.61, p = 0.01). In conclusion, a 4-month intradialytic exercise program can enhance body composition and some physical parameters in HD patients awaiting kidney transplantation.

Abstract
BACKGROUND Maintenance hemodialysis(MHD) patients often suffer from fatigue and are recommended to undertake physical activities. The optimal format of exercise rehabilitation for MHD patients remains uncertain despite demonstrated health benefits. This study aimed to evaluate the effectiveness of an intradialytic group exercise programme for MHD patients. METHODS This was a single-centre, single-group repeated-measures design study. The 12-week, three times per-week intradialytic group exercise programme was conducted for around 30 min during the first 2 hours of each dialysis session. Patient-reported outcomes including fatigue, anxiety, depression and health-related quality of life, laboratory parameters including haemoglobin, albumin, pre-albumin and hypersensitive C-reactive protein, and anthropometric parameters including triceps skinfold thickness, mid-upper arm circumference, mid-arm muscle circumference and handgrip strength, were measured at baseline, immediately post-intervention and 12-weeks post-intervention. The repeated-measures analysis of variance and Friedman test were used to compare the parametric and non-parametric data across time points, respectively. RESULTS Ninety patients were enrolled and 75 completed. Participants reported significant improvements across time points in fatigue (F = 10.19, p < 0.01), depression (F = 19.20, p < 0.001), health-related quality of life (F = 5.36, p = 0.006), haemoglobin (F = 3.43, p = 0.047), albumin (F = 4.42, p = 0.032), hypersensitive C-reactive protein (χ 2 = 50.39, p < 0.001), pre-albumin (χ 2 = 11.85, p = 0.003), triceps skinfold thickness (F = 25.03, p < 0.001), mid-upper arm circumference (F = 6.32, p = 0.005), mid-arm muscle circumference (F = 4.89, p = 0.02), and handgrip strength (F = 13.59, p < 0.001). Although the mean anxiety score tended to reduce, the difference across time points was nonsignificant (F = 1.33, p = 0.27). CONCLUSION The findings suggested that the intradialytic group exercise programme could improve MHD patients' fatigue, depression, health-related quality of life, nutritional status, and inflammation.

Abstract
Abstract
Background
Depression is associated with morbidity, death, diminished quality of life, decreased longevity, and even suicidal ideation in hemodialysis patients. Intra-dialytic exercise is considered as integral component of the clinical care management of hemodialysis patients as it improves hemodialysis effectiveness, reducing systemic inflammation, increasing exercise tolerance, decreasing depression and improving quality of life. The objective of this study was to assess the effect of intra-dialytic physical exercise on depression and physical activity in prevalent hemodialysis patients. This prospective cohort research comprised 50 hemodialysis patients maintained on regular hemodialysis 3 times/week with duration since starting dialysis (1–5 years), not practicing any previous physical activity, suffering from depressive symptoms, not maintained on antidepressants and separated into two groups: group I underwent intra-dialytic exercise for 3 months and group II was matched in age and gender but did not undertake any exercise.
Results
Hamilton depression rating scale was significantly decreased in group I after completing the exercise program compared to baseline (P = 0.000), while there was no significant change in group II. Serum tumor necrosis factor alpha significantly decreased in group I compared to baseline (P = 0.000), while there was no significant change in group II. A positive correlation was found between serum tumor necrosis factor alpha and Hamilton depression rating scale (r = 0.676), (P = 0.000). Physical activity tests; 6-min walk test, rapid assessment of physical activity and peak volume of oxygen consumption were significantly improved in group I compared to baseline (P = 0.000), while there was no statistically significant difference in group II. Serum phosphorus and parathyroid hormone levels were significantly decreased in group I compared to baseline (P < 0.01), while urea reduction ratio was significantly increased in group I compared to baseline (P = 0.000), but there was no significant change in group II.
Conclusions
Intra-dialysis exercise can improve depression and physical performance in hemodialysis patients. As positive correlation was found between serum tumor necrosis factor alpha and Hamilton depression rating scale, so tumor necrosis factor alpha may be considered as marker of depression in hemodialysis patients. Intra-dialytic exercise can improve dialysis efficacy by improving urea reduction ratio.

Abstract
OBJECTIVE To conduct an overview of meta-analyses evaluating the impact of exercise interventions on improving health outcomes in patients with chronic kidney disease (CKD). DESIGN An umbrella review of systematic review and meta-analyses of intervention trials was performed. DATA SOURCES PubMed, Web of Science, Embase and the Cochrane Database of Systematic Reviews were searched from inception to 9 March 2021 for relevant articles. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Eligible meta-analyses compared the effects of usual care with and without exercise in patients with CKD. Health outcomes included those related to cardiovascular risk factors, physical fitness, dialysis-related symptoms, dialysis adequacy and health-related quality of life. Systematic reviews and meta-analyses that included fewer than 3 RCTs or fewer than 100 participants were excluded from the analysis. RESULTS A total of 31 eligible systematic reviews and meta-analyses were included that assessed 120 outcomes. For physical fitness, there was a moderate effect size for cardiorespiratory fitness, muscle strength and body composition and small effect size for muscle endurance. The effect sizes for cardiovascular risk factors, dialysis-related symptoms and health-related quality of life outcomes were small. According to the Grading of Recommendations Assessment, Development and Evaluation framework, most outcomes were low or very low quality. CONCLUSION Exercise appears to be a safe way to affect concomitant cardiovascular risk factors, such as blood pressure, improve physical fitness and health-related quality of life and reduce dialysis-related symptoms in patients with CKD.

Abstract
Health-related quality of life (HRQoL) of patients suffering from chronic kidney disease (CKD) is profoundly impaired by their frailty, disability and decreased physical capacity. Especially among older patients, a high prevalence of low physical activity levels and reduced functional performance has been reported. Physical exercise training has been shown to have a beneficial impact, counteracting these same hazardous consequences of inactivity and sedentarism both on CKD and end-stage kidney disease (ESKD) patients on hemodialysis (HD) treatment. The evidence-based knowledge on the effects of physical exercise on ESKD patients undergoing Peritoneal Dialysis (PD) treatment is scarce, even though this is a continually growing population that shares the same risk factors and desired clinical outcomes as the previously mentioned groups of patients. Further investigation will be necessary to clarify whether this exercise-based approach may be suitable for the PD population. This paper's purpose is to review the available literature, including randomized controlled trials, reviews and meta-analysis results that assessed the impact of physical exercise on patients under PD treatment bearing in mind their HRQoL, physical functioning and cardiovascular parameters. Furthermore, it aims to evaluate the perceived significant barriers and limitations of the PD population in what concerns physical exercise practice and how nephrologists should address them.

Can J Kidney Health Dis 2021; 8:20543581211056233. [PMID: 34777843 PMCID: PMC8586186 DOI: 10.1177/20543581211056233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Accepted: 09/11/2021] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND There is growing evidence demonstrating the benefits of intradialytic cycling. However, there are relatively few centers where this practice has been adopted with no reports from hemodialysis units in rural, remote, and northern locations. Maintaining mobility and quality of life for patients on kidney replacement therapy living in remote northern communities is inhibited by inclement weather and lack of access to resources and infrastructure that support physical activity. The integration of intradialytic cycling during hemodialysis offers patients a form of safe physical activity year-round. OBJECTIVE This study focuses on better understanding the feasibility and acceptability of implementing intradialytic cycling in a remote northern geographical context. DESIGN A feasibility study using a mixed-methods explanatory design was adopted for this study. SETTING The research is conducted in Prince George, British Columbia. PARTICIPANTS The participants are patients attending a community-based dialysis unit in remote northern British Columbia and health professionals working in the same facility. METHODS Quantitative measures were captured through cycling logbooks and quality of life measure, and qualitative data were obtained through semi-structured interviews and analyzed using thematic analysis. RESULTS Six (43%) eligible patients used leg ergometers more than once for a median of 2.5 (interquartile range: 1-4) months and 87% of hemodialysis sessions. Participants cycled for a median of 65 (interquartile range: 39-76) minutes per session, with frequent variability noted between participants and different hemodialysis sessions for the same participant. Nine patients completed the European Quality of Life Health Questionnaire prestudy, with 5 (56%) also completing it poststudy. Interviews with 9 patients, 4 nurses, and 1 physiotherapist led to the identification of themes instrumental to implementation: a supportive community dialysis unit, shared responsibility, knowledge of patients/providers, and benefits associated with engagement. Themes that were identified as being key to acceptability in this remote dialysis unit were trust, connection, and engagement through common values. LIMITATIONS Due to dialysis unit size, we had a small number of participants. CONCLUSIONS This study demonstrates the feasibility of implementing best practice in a remote community and provides insight into the elements of context and participation that contribute to acceptability in the implementation of intradialytic cycling.

Association between the transtheoretical model approach and sustained intradialytic pedaling exercise: A retrospective cohort study. Medicine (Baltimore) 2021; 100:e27406.

Abstract
The transtheoretical model (TTM) is a promising approach to the promotion of behavior change, but it remains to be established whether there is an association between the TTM approach and intradialytic exercise among patients on hemodialysis (HD) with low motivation to exercise in a real-world setting.This retrospective cohort study, conducted in a regional hospital in Japan, included adult outpatients receiving HD 3 times per week who had never participated in intradialytic pedaling exercise despite the encouragement of the HD personnel. Patients were divided into 2 groups according to HD weekday. Patients undergoing HD on Tuesday, Thursday, and Saturday were encouraged by the HD unit team to exercise during HD based on the TTM (exposure group) and those receiving HD on Monday, Wednesday, and Friday were encouraged to exercise as usual (control group). The primary outcome was sustained intradialytic exercise using a leg ergometer, defined as a total of 72 sessions of 30-minute pedaling exercise (duration of at least 6 months).Overall, 85 patients were included in the analysis (mean age: 67.1 ± 11.9 years, 22% female). Of 33 patients in the exposure group, 10 (30%) maintained intradialytic exercise, compared with 2 of 52 patients (4%) in the control group. Log-binomial regression models with stabilized inverse probability of treatment weighting showed a significant association between the TTM approach and sustained intradialytic exercise (adjusted risk ratio 9.23 [95% confidence interval 2.13-40.00]). There were no exercise-related cardiovascular events.Among patients with low motivation to exercise during HD, use of the TTM approach in clinical practice was associated with sustained intradialytic exercise compared with usual care.

Amino acid removal during hemodialysis can be compensated for by protein ingestion and is not compromised by intradialytic exercise: a randomized controlled crossover trial. Am J Clin Nutr 2021; 114:2074-2083.

Abstract
BACKGROUND Patients with end-stage renal disease (ESRD) undergoing hemodialysis experience a rapid decline in skeletal muscle mass and strength. Hemodialysis removes amino acids (AAs) from the circulation, thereby lowering plasma AA concentrations and stimulating proteolysis. OBJECTIVES In the present study, we evaluate the impact of intradialytic protein ingestion at rest and following exercise on AA removal and plasma AA availability in patients with ESRD. METHODS Ten patients (age: 65 ± 16 y, male/female: 8/2, BMI: 24.2 ± 4.8 kg/m2, serum albumin: 3.4 ± 0.3 g/dL) with ESRD undergoing hemodialysis participated in this randomized controlled crossover trial. During 4 hemodialysis sessions, patients were assigned to ingest 40 g protein or a placebo 60 min after initiation, both at rest (PRO and PLA, respectively) and following exercise (PRO + EX and PLA + EX, respectively). Spent dialysate and blood samples were collected every 30 min throughout hemodialysis to assess AA removal and plasma AA availability. RESULTS Plasma AA concentrations declined by 26.1 ± 4.5% within 30 min after hemodialysis initiation during all interventions (P < 0.001, η2p > 0.79). Protein ingestion, but not intradialytic exercise, increased AA removal throughout hemodialysis (9.8 ± 2.0, 10.2 ± 1.6, 16.7 ± 2.2, and 17.3 ± 2.3 g during PLA, PLA + EX, PRO, and PRO + EX interventions, respectively; protein effect P < 0.001, η2p = 0.97; exercise effect P = 0.32, η2p = 0.11). Protein ingestion increased plasma AA concentrations until the end of hemodialysis, whereas placebo ingestion resulted in decreased plasma AA concentrations (time effect P < 0.001, η2p > 0.84). Plasma AA availability (incremental AUC) was greater during PRO and PRO + EX interventions (49 ± 87 and 70 ± 34 mmol/L/240 min, respectively) compared with PLA and PLA + EX interventions (-227 ± 54 and -208 ± 68 mmol/L/240 min, respectively; protein effect P < 0.001, η2p = 0.98; exercise effect P = 0.21, η2p = 0.16). CONCLUSIONS Protein ingestion during hemodialysis compensates for AA removal and increases plasma AA availability both at rest and during recovery from intradialytic exercise. Intradialytic exercise does not compromise AA removal or reduce plasma AA availability during hemodialysis in a postabsorptive or postprandial state.

Abstract
BACKGROUND Intradialytic exercise (IDE) may improve physical function and health-related quality of life. However, incorporating IDE into standard hemodialysis care has been slow due to feasibility challenges. We conducted a multicenter qualitative feasibility study to identify potential barriers and enablers to IDE and generate potential solutions to these factors. METHODS We conducted 43 semi-structured interviews with healthcare providers and patients across twelve hospitals in Ontario, Canada. We used the Theoretical Domains Framework and directed content analysis to analyze the data. RESULTS We identified eight relevant domains (knowledge, skills, beliefs about consequences, beliefs about capabilities, environmental context and resources, goals, social/professional role and identity, and social influences) represented by three overarching categories: 1) Knowledge, skills and expectations: lack of staff expertise to oversee exercise, uncertainty regarding exercise risks, benefits, and patient interest, lack of knowledge regarding exercise eligibility; 2) Human, material and logistical resources: staff concerns regarding workload, perception that exercise professionals should supervise IDE; space, equipment, and scheduling conflict concerns; 3) Social dynamics of the unit: local champions and patient stories contribute to IDE sustainability.We developed a list of actionable solutions by mapping barriers and enablers to behavior change techniques. We also developed a feasibility checklist of 47 questions identifying key factors to address prior to IDE launch. CONCLUSIONS Evidence-based solutions to identified barriers and enablers to IDE and a feasibility checklist may help recruit and support units, staff, and patients and address key challenges to the delivery of IDE in diverse clinical and research settings.

Abstract
Abstract
Background
Chronic kidney disease increases the risk of fractures and altered bone and mineral metabolism. Exercise training could be a non-pharmacological therapeutic intervention. The aim of this work is to evaluate the effect of intradialytic exercise training on bone markers in hemodialysis (HD) patients.
Results
Forty adult patients on regular HD participated in the study. Twenty of which completed 3 months supervised intradialytic cycling exercise program and 20 served as controls. At baseline, there was no difference between both groups regarding age, sex, physical performance, and laboratory studies performed. After 3 months, the exercise group showed significant improvement in short performance battery test (SPBT) total score (P<0.001) associated with significant decrease in serum parathormone (PTH) (P=0.01) and increase in serum alkaline phosphatase (ALP) and bone specific alkaline phosphatase (BALP) (P<0.05 and P<0.001 respectively). Controls did not show similar change in SPBT or laboratory studies. There was no significant change in serum calcium or phosphorus in both groups. A significant positive correlation was observed between SPBT scores post-exercise and both BALP and ALP levels (r=0.432, P=0.01 and r=0.645, P<0.01 respectively). Also, an inverse relation was observed between SPBT and PTH (r=−0.503, P=0.01).
Conclusion
Intradialytic cycling exercise program resulted in significant increase in physical performance associated with decrease in serum PTH and increase in BALP and ALP in HD patients. This indicates the positive influence of exercise not only on physical performance in dialysis patients but also on bone metabolism.

Abstract
Background Intradialytic exercises are recommended to be available as a treatment for enhancing physical functioning. However, there have been few reports which evaluated the results of long-term mild intradialytic exercises in elderly patients. The purpose of this study is to investigate the changes in body weight, body composition, and laboratory data in elderly hemodialysis patients after 1-year intradialytic leg exercises with resistance bands. Methods A retrospective study. Twenty-one outpatients, aged 65 or older (mean ± SD, 75.2 ± 5.1 years), received intradialytic leg exercises with resistance bands for a year were analyzed. The values of dry weight, body composition, and laboratory data were collected from the year-ago period, at baseline and 1 year after baseline. Fat and muscle mass were evaluated by using a multi-frequency bioimpedance device. Results Physical performance changed and body weight increased after 1-year resistance band exercises. However, the participants gained fat mass, not muscle mass. Although the changes in biochemical data related to protein intake were equivocal, triglyceride levels increased significantly after 1-year exercises. An elevation in serum creatinine levels was observed, even if solute clearance increased significantly. Conclusions One-year intradialytic leg exercises with resistance bands may have a potential clinical benefit for body mass index even in elderly hemodialysis patients. However, optimal dietary modification is needed to achieve a balanced increase of muscle and fat mass. An increase of serum creatinine levels does not always mean muscle mass hypertrophy.

Abstract
Both intradialytic and out-of-clinic exercise programs (EP) have been proven to be a safe and effective way to increase fitness levels in end-stage chronic kidney disease (CKD) patients. The actual COVID-19 pandemic situation has forced the suspension of EP offered in hemodialysis centers in many countries; as well as all activities considered as "non-essential" (i.e., sport facilities and fitness centers). Therefore, there is a high risk that movement restrictions would promote physical inactivity and its associated diseases in CKD patients; especially those undergoing domiciliary confinement situations. Given the importance for CKD patients' overall health to maintain exercise levels and reach physical activity recommendations, the aim of this Protocol was to design a personalized, well-structured, multicomponent physical EP that CKD patients can safely follow at home. We also aimed to provide an initial fitness evaluation tool that allows patients to adapt the EP to their fitness level. Current general exercise recommendations for people living with chronic conditions have been analyzed to develop the present home-based EP proposal.

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.

Abstract
OBJECTIVE(S) Patients with end-stage kidney disease requiring hemodialysis suffer frailty and poor physical function. Exercise can improve physical function; however, barriers exist to intradialytic exercise programs. The objective of this study was to explore patients' reasons for not exercising in an extant intradialytic exercise program. DESIGN AND METHODS We conducted a retrospective analysis reporting the reasons for not exercising in an intradialytic exercise program in two hemodialysis centers over a 4-week period. We explored whether patient characteristics and the presence of an exercise professional were associated with missed exercise sessions. RESULTS Seventy-five patients participating in the intradialytic exercise program completed 57% of prescribed intradialytic exercise sessions. The three most frequently reported reasons from patients not exercising were refusal (24%), followed by fatigue (19%) and symptoms (14%). Patients were more than twice as likely to exercise if a kinesiologist was present (odds ratio [OR]: 2.26, confidence interval [CI]: 1.5, 3.4 P = .03). They were less likely to exercise if they were women (OR: 0.66, CI: 0.45, 0.95 P = .002), had been on dialysis greater than 60 months (OR: 0.55, CI: 0.37, 0.80 P < .002), or had more than two comorbid conditions (OR: 0.63, CI: 0.43, 0.90, P = .01). CONCLUSION Patient adherence to intradialytic exercise programs is strongly associated with the presence of exercise professionals.

Impact of hemodialysis and post-dialysis period on granular activity levels. BMC Nephrol 2020; 21:197.

Abstract
Background Physical activity (PA) is typically lower on hemodialysis (HD) days. Albeit intradialytic inactivity is expected, it is unknown whether recovery after HD contributes to low PA. We investigated the impact of HD and post-HD period on granular PA relative to HD timing. Methods We used baseline data from the HDFIT trial conducted from August 2016 to October 2017. Accelerometry measured PA over 1 week in patients who received thrice-weekly high-flux HD (vintage 3 to 24 months), were clinically stable, and had no ambulatory limitations. PA was assessed on HD days (0 to ≤24 h after start HD), first non-HD days (> 24 to ≤48 h after start HD) and second non-HD day (> 48 to ≤72 h after start HD). PA was recorded in blocks/slices: 4 h during HD, 0 to ≤2 h post-HD (30 min slices), and > 2 to ≤20 h post-HD (4.5 h slices). Blocks/slices of PA were captured at concurrent/parallel times on first/second non-HD days compared to HD days. Results Among 195 patients (mean age 53 ± 15 years, 71% male), step counts per 24-h were 3919 ± 2899 on HD days, 5308 ± 3131 on first non-HD days (p < 0.001), and 4926 ± 3413 on second non-HD days (p = 0.032). During concurrent/parallel times to HD on first and second non-HD days, patients took 1308 and 1128 more steps (both p < 0.001). Patients took 276 more steps and had highest rates of steps/hour 2-h post-HD versus same times on first non-HD days (all p < 0.05). Consistent findings were observed on second non-HD days. Conclusions PA was higher within 2-h of HD versus same times on non-HD days. Lower PA on HD days was attributable to intradialytic inactivity. The established PA profiles are of importance to the design and development of exercise programs that aim to increase activity during and between HD treatments. Trial registration HDFIT was prospectively registered 20 April 2016 on ClinicalTrials.gov (NCT02787161)

Abstract
Intradialytic cycling is a widely used workout mode, whereas added benefit of other exercise modalities remains unknown. This is the first randomised controlled trial on the effects and sustainability of functional training and counselling in addition to intradialytic cycling. Patients were randomly assigned to a kinesiologist-guided functional training in addition to intradialytic cycling (n = 20, experimental group) or intradialytic cycling only (n = 20, control group) over 16 weeks. The experimental group attended predialysis functional exercise in the first eight weeks and afterward performed functional training at home for the next eight weeks. The primary study endpoint was 10-repetition-sit-to-stand test time at eight weeks: at this test, the experimental group improved significantly better than controls (-4.5 ± 1.9 s, 95%CI -8.4 to -0.7; P = 0.021), which was maintained at week 16 (-4.7 ± 2.1 s, 95%CI -9.0 to -0.3; P = 0.037). At week 8, the experimental group significantly outperformed controls also at handgrip strength (P = 0.004), lower body flexibility test (P < 0.001), balance test (P < 0.001), and upper body flexibility test (P = 0.003). At week 16, superior results of the experimental group in secondary end-points remained preserved for handgrip strength, balance, and upper body flexibility tests. Functional training with exercise counselling meaningfully improves physical performance and successfully prepares patients for sustainable home exercise.

Abstract
Dialysis and nutrition are two sides of the same coin—dialysis depurates metabolic waste that is typically produced by food intake. Hence, dietetic restrictions are commonly imposed in order to limit potassium and phosphate and avoid fluid overload. Conversely, malnutrition is a major challenge and, albeit to differing degrees, all nutritional markers are associated with survival. Dialysis-related malnutrition has a multifactorial origin related to uremic syndrome and comorbidities but also to dialysis treatment. Both an insufficient dialysis dose and excessive removal are contributing factors. It is thus not surprising that dialysis alone, without proper nutritional management, often fails to be effective in combatting malnutrition. While composite indexes can be used to identify patients with poor prognosis, none is fully satisfactory, and the definitions of malnutrition and protein energy wasting are still controversial. Furthermore, most nutritional markers and interventions were assessed in hemodialysis patients, while hemodiafiltration and peritoneal dialysis have been less extensively studied. The significant loss of albumin in these two dialysis modalities makes it extremely difficult to interpret common markers and scores. Despite these problems, hemodialysis sessions represent a valuable opportunity to monitor nutritional status and prescribe nutritional interventions, and several approaches have been tried. In this concept paper, we review the current evidence on intradialytic nutrition and propose an algorithm for adapting nutritional interventions to individual patients.

Abstract
There is a lack of agreement on the efficacy of different exercise interventions in hemodialysis patients. We analyzed which exercise type is the most beneficial in terms of functional fitness and inflammation. A literature search of seven databases yielded 33 studies that met the inclusion criteria. Compared with an inactive control, the intervention group showed moderate effects (ES = 0.74; 95% CI 0.35 to 1.14; p < 0.001; and ES = 0.70; 95% CI 0.39 to 1.01; p < 0.001; respectively) on functional capacity (six-minute walk test) and oxygen consumption. Small nonsignificant effects were observed for aerobic (ES = -0.36; 95% CI -0.85 to 0.13; p = 0.154) and resistance (ES = -0.44; 95% CI -1.07 to 0.19; p = 0.169) training types, whereas moderate effects were found for combined (ES = -0.69; 95% CI -1.47 to 0.10; p = 0.088) training type based on a 10-repetition sit-to-stand test. Further, large and small effects were observed for aerobic (ES = -1.21; 95% CI -1.94 to -0.49; p = 0.001) and resistance training (ES = -0.54; 95% CI -0.90 to -0.17; p = 0.004) types on C-reactive protein. Overall, the results showed the numerically largest effect sizes for combined types compared to solely aerobic or resistance training types, with the differences between training types not reaching statistical significance. There was a significant modifying impact of age, training frequency, and session duration on performance and inflammatory outcomes.

Abstract
Objectives Patients with end-stage renal disease (ESRD) undergoing haemodialysis (HD) have significantly reduced cardiorespiratory fitness and health-related quality of life (HRQoL). Our hypothesis was that high-intensity interval training (HIIT) is a feasible and safe form of exercise during HD and that HIIT would elicit greater change in cardiorespiratory fitness and HRQoL compared with moderate-intensity continuous training (MICT). Methods Twenty patients were randomised to either HIIT (n=6), MICT (n=8) (two times a week within 22 weeks) or usual care (n=6). Feasibility was assessed by session attendance and adherence to exercise intensity. Safety was assessed by adverse event reporting. Efficacy was determined from change in peak oxygen uptake (VO2peak), 6 min walk distance and a HRQoL questionnaire (the COOP-WONCA chart). Results Eleven patients (55%) completed premeasurements and postmeasurements. The main reason for drop-out was due to kidney transplant during follow-up. The patients completed the same number of sessions in each group and adhered to the target heart rates after habituation. There were no adverse events. In the HIIT group, two of the three patients increased VO2peak by 46% and 53%, respectively. Three of the five patients in the MICT group increased their VO2peak by 6%, 18% and 36%, respectively. Conclusions This pilot study demonstrated that HIIT is a feasible and safe exercise model for intradialytic exercise in patients undergoing HD. There might be a considerable potential of intradialytic HIIT in patients undergoing HD. Further studies with larger sample sizes are needed to determine if HIIT is an optimal approach in patients with ESRD undergoing HD. Trial registration number NCT01728415.

Abstract
Despite having good intentions, hemodialysis (HD) clinics often fail to sustain exercise programs that they initiate. There are many reasons for this, including a lack of funding, inadequate training of the clinic staff, a lack of exercise professionals to manage the program or train the staff, and the many challenges inherent to exercising a patient population with multiple comorbid diseases. Despite these barriers, there are several outstanding examples of successful exercise programs in HD clinics throughout the world. The aim of this manuscript is to review the characteristics of four successfully sustained HD exercise programs in Portugal, Canada, Mexico, and Germany. We describe the unique approaches they have used to fund and manage their programs, the varied exercise prescriptions they incorporate, the unique challenges they face, and discuss the benefits they have seen. While the programs differ in many regards, a consistent theme is that they each have substantial and committed support from the entire clinic staff, including the nephrologists, administration, nurses, dietitians, and technicians. This suggests that exercise programs in HD clinics can be successfully implemented and sustained provided significant effort is made to foster a culture of physical activity throughout the clinic.

Abstract
OBJECTIVE To assess the efficacy and safety of intradialytic exercise for haemodialysis patients. DESIGN Systematic review and meta-analysis. DATA SOURCES Databases, including PubMed, Embase, the Cochrane Library, China Biology Medicine and China National Knowledge Infrastructure, were screened from inception to March 2017. ELIGIBILITY CRITERIA Randomised controlled trials (RCTs) aimed at comparing the efficacy and safety of intradialytic exercise versus no exercise in adult patients on haemodialysis for at least 3 months. A minimum exercise programme period of 8 weeks. DATA EXTRACTION Study characteristics and study quality domains were reviewed. Studies were selected, and data extracted by two reviewers. DATA ANALYSIS The pooled risk ratios and mean differences (MDs) with 95% CIs for dichotomous data and continuous data were calculated, respectively. RESULTS A total of 27 RCTs involving 1215 subjects were analysed. Compared with no exercise, intradialytic exercise increased dialysis adequacy (Kt/V) (MD 0.07, 95% CI 0.01 to 0.12, p=0.02) and maximum volume of oxygen that the body can use during physical exertion peak oxygen consumption (MD 4.11, 95% CI 2.94 to 5.27, p<0.0001), alleviated depression standardised mean difference (-1.16, 95% CI -1.86 to -0.45, p=0.001) and improved physical component summary-short form-36 (SF-36) level (MD 7.72, 95% CI 1.93 to 13.51, p=0.009). Also, intradialytic exercise could significantly reduce systolic blood pressure (MD -4.87, 95% CI -9.20 to -0.55, p=0.03) as well as diastolic blood pressure (MD -4.11, 95% CI -6.50 to -1.72, p=0.0007). However, intradialytic exercise could not improve mental component summary-SF-36 level (MD 3.05, 95% CI -1.47 to 7.57, p=0.19). There was no difference in the incidence of adverse events between the intradialytic exercise and control groups. CONCLUSIONS Intradialytic exercise resulted in benefits in terms of improving haemodialysis adequacy, exercise capacity, depression and quality of life for haemodialysis.

Abstract
Introduction: Haemodialysis patients are at an increased risk of sarcopenia. Physical inactivity is now recognised as a major cause of muscle wasting in haemodialysis patients. It is unclear as to what and how much exercise is required to show benefit. We therefore performed a pilot study of cycling during haemodialysis. Methods: Patients underwent a progressive submaximal individualised cycling exercise, 3× a week during haemodialysis for 4 months using bed-cycle ergometers. Body composition was measured by multifrequency segmental bioimpedance and muscle function by 6-min walking test, and hand grip strength and pinch strength. Results: In total, 56% of patients in a dialysis centre fulfilled exercise study inclusion criteria and 13 (72.2%) of 18 patients completed the exercise programme, with the mean age of 64.0 ± 16.6 years and 76.9% being male. The 6-min walking test increased following exercise from 349 ± 105 to 398 ± 94.2 m, p < 0.05, as did both hand grip strength and pinch strength, with 20.4 ± 9.1 versus 23.4 ± 9.9 kg, p < 0.01, and 4.3 ± 1.8 versus 5.9 ± 2.4 kg, p < 0.05, respectively. There were no changes in appendicular muscle mass or other body composition detected with bioimpedance in either the exercise group, or 21 control patients, propensity matched for body composition, comorbidity and frailty. Muscle strength did not change in the control group. Haemodialysis sessional Kt/Vurea was greater at the end of the exercise programme compared to controls (1.63 ± 0.63 vs 1.21 ± 0.12, p < 0.01). Conclusion: The majority of dialysis centre patients met our exercise study entry criteria and could potentially benefit from cycling during haemodialysis. We found that muscle function and strength improved after a 4-month, thrice weekly cycling exercise programme.

Implementing a theory-based intradialytic exercise programme in practice: a quality improvement project. Clin Kidney J 2018; 11:832-840. [PMID: 30524718 PMCID: PMC6275440 DOI: 10.1093/ckj/sfy050] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2018] [Accepted: 05/17/2018] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Research evidence outlines the benefits of intradialytic exercise (IDE), yet implementation into practice has been slow, ostensibly due to a lack of patient and staff engagement. The aim of this quality improvement project was to improve patient outcomes via the introduction of an IDE programme, evaluate patient uptake and sustainability and enhance the engagement of routine haemodialysis (HD) staff with the delivery of the IDE programme. METHODS We developed and refined an IDE programme, including interventions designed to increase patient and staff engagement that were based on the Theoretical Domains Framework (TDF), using a series of 'Plan, Do, Study, Act' (PDSA) cycles. The programme was introduced at two UK National Health Service HD units. Process measures included patient uptake, withdrawals, adherence and HD staff involvement. Outcome measures were patient-reported functional capacity, anxiety, depression and symptomology. All measures were collected over 12 months. RESULTS A total of 95 patients were enrolled in the IDE programme; 64 (75%) were still participating at 3 months, decreasing to 41 (48%) at 12 months. Adherence was high (78%) at 3 months, decreasing to 63% by 12 months. The provision of IDE by HD staff accounted for a mean of 2 (5%) sessions per 3-month time point. Patients displayed significant improvements in functional ability (P = 0.01) and a reduction in depression (P = 0.02) over 12 months, but the effects seen were limited to those who completed the programme. CONCLUSIONS A theory-based IDE programme is feasible and leads to improvement in functional capacity and depression. Sustaining IDE over time is complicated by high levels of patient withdrawal from the programme. Significant change at an organizational level is required to enhance sustainability by increasing HD staff engagement or access to professional exercise support.

Hemodynamic Instability during Dialysis: The Potential Role of Intradialytic Exercise. BIOMED RESEARCH INTERNATIONAL 2018; 2018:8276912. [PMID: 29682559 PMCID: PMC5848102 DOI: 10.1155/2018/8276912] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2017] [Accepted: 01/24/2018] [Indexed: 12/11/2022]
Abstract
Acute haemodynamic instability is a natural consequence of disordered cardiovascular physiology during haemodialysis (HD). Prevalence of intradialytic hypotension (IDH) can be as high as 20–30%, contributing to subclinical, transient myocardial ischemia. In the long term, this results in progressive, maladaptive cardiac remodeling and impairment of left ventricular function. This is thought to be a major contributor to increased cardiovascular mortality in end stage renal disease (ESRD). Medical strategies to acutely attenuate haemodynamic instability during HD are suboptimal. Whilst a programme of intradialytic exercise training appears to facilitate numerous chronic adaptations, little is known of the acute physiological response to this type of exercise. In particular, the potential for intradialytic exercise to acutely stabilise cardiovascular hemodynamics, thus preventing IDH and myocardial ischemia, has not been explored. This narrative review aims to summarise the characteristics and causes of acute haemodynamic instability during HD, with an overview of current medical therapies to treat IDH. Moreover, we discuss the acute physiological response to intradialytic exercise with a view to determining the potential for this nonmedical intervention to stabilise cardiovascular haemodynamics during HD, improve coronary perfusion, and reduce cardiovascular morbidity and mortality in ESRD.
