Functional and Respiratory Capacity of Patients with Chronic Kidney Disease Undergoing Cycle Ergometer Training during Hemodialysis Sessions: A Randomized Clinical Trial

Abstract

Purpose Exercise is recommended for patients undergoing hemodialysis, to reduce the decrease in functional capacity secondary to the progression of chronic kidney disease. A cycle ergometer can be easily added to an exercise routine during hemodialysis sessions. The purpose of this article was to assess the results of a training protocol with the cycle ergometer during hemodialysis sessions on the respiratory function and functional capacity of patients with chronic kidney disease on hemodialysis. Method In this randomized clinical trial (NCT no. 02834026), 39 patients undergoing hemodialysis were randomly allocated into two groups: the treatment group (TG, n = 20), who underwent a cycle ergometer protocol training, and the control group (GC, n = 19), not trained. The TG attended 24 training sessions, three times a week, during the intradialytic period. Training intensity was aimed at keeping the heart rate between 50 and 70% of its maximum. All participants were evaluated before and after the eight consecutive weeks of follow-up and had biochemicals data, anthropometric, functional, and respiratory outcomes evaluated. Results A significant difference was observed between groups in forced vital capacity, forced expiratory volume in the first second, peak expiratory flow, maximal inspiratory and expiratory pressure, and Borg score and distance covered in the six-minute walk test. Improvement was also observed in biochemical and Kt/V test results for the TG. Conclusion The systematic training regimen with a cycle ergometer resulted in benefits in the respiratory function and functional capacity in patients with chronic kidney disease undergoing hemodialysis.

Ventilatory and chronotropic incompetence during incremental and constant load exercise in end-stage renal disease: a comparative physiology study

“…Lung function was reduced at rest in participants with ESRD, suggestive of chronic deconditioning. Although not extensively documented, these data add to the limited existing literature by directly comparing ESRD with age-and sexmatched healthy controls (6,7). Restrictive lung dysfunction is present in a third of individuals with ESRD (20), although it was not evident in our data.…”

The optimal exercise modality and intensity for hemodialysis patients incorporating Bayesian network meta-analysis and systematic review

“…Nineteen studies compared the effects of AT and the control group ( Painter et al, 2002 ; Tsuyuki et al, 2003 ; Sakkas et al, 2008 ; Toussaint et al, 2008 ; Koh et al, 2010 ; Reboredo Mde et al, 2010 ; Wilund et al, 2010 ; Giannaki et al, 2013 ; Mohseni et al, 2013 ; Wu et al, 2014 ; Groussard et al, 2015 ; Liao et al, 2016 ; Pomidori et al, 2016 ; Cooke et al, 2018 ; Fernandes et al, 2019 ; Lin et al, 2021 ; Perez-Dominguez et al, 2021 ; Kim et al, 2022 ; Vogiatzaki et al, 2022 ). Nine studies evaluated RT and the control group.…”

Aerobic and Anaerobic Exercise to Enhance Physical Fitness of Chronic Kidney Disease Patients on Hemodialysis: A Literature Review

“…The mechanism could be explained by increasing strength in type I muscles in the lower extremities that reflecting lung function. However, this hypothesis requires further research (Fernandes et al, 2019). Guidelines Of National Kidney Foundation (KDIGO, 2013), Exercise should be one of the pillars of therapy for adult patients undergoing hemodialysis with the aim of controlling cardiovascular risk factors (Lok et al, 2020).…”
