The Effect of Intradialytic Aerobic Exercise on Dialysis Efficacy in Hemodialysis Patients: A Randomized Controlled Trial

Abstract

Objective: This study was conducted to determine the impact of an 8-week intradialytic exercise program (consisting of 15 minutes low-intensity exercise during the first 2 hours of dialysis) on dialysis efficacy.Methods: In an open randomized controlled trial, a total of 50 clinically stable hemodialysis patients were enrolled into the study and randomly allocated into two groups: the aerobic exercise group (n=25) and the control group (n=25). Aerobic exercises were done in the intervention group for 15 min/day, three times a week for 2 months. The dialysis efficacy was assessed prior to and at the end of each month of the program.Results: The efficacy of dialysis increased at the end of the first month and remained elevated for the duration of the program in the exercise group (p<0.05).Conclusion: A simplified aerobic exercise program has increased the efficacy of dialysis and may be considered as a safe, complementary and effective modality for hemodialysis patients.
