BackgroundThe aim of this study was to assess the effect of intradialytic cycling exercise on quality of life (QOL) and recovery time in patients who underwent hemodialysis.Materials And MethodsHemodialysis patients were recruited from the referral dialysis centers affiliated with Isfahan University of Medical Sciences, Isfahan, Iran. Patients were randomly assigned into the intervention and the control groups. Patients in the intervention group exercised on a stationary bike for 12 weeks (3 times per week for 30 min); however, patients in the control group received usual hemodialysis. The kidney disease QOL (KDQOL)-short-form version 1.3 was used to assess QOL. Patients were asked to answer the question "How long does it take to recover from a dialysis session?" to assess recovery time.ResultsA total of 110 hemodialysis patients, including 60 in the intervention group and 50 in the control group were analyzed. A significant increase was observed in the generic (mean difference ± SE: 1.50 ± 0.44, P = 0.001), kidney disease (mean difference ± SE: 0.84 ± 0.28, P = 0.004), and overall QOL (mean difference ± SE: 1.18 ± 0.33, P = 0.001) scores after 12 weeks of intradialytic cycling exercise in the intervention group. Furthermore, a significant difference was noted between the intervention and the control group regarding the mean difference of all QOL scores after the intervention (P < 0.05). We also found a significant difference in the mean difference of recovery time between the intervention and the control group after the intervention (P < 0.001).ConclusionKDQOL and recovery time could improve in hemodialysis patients after 12-week intradialytic exercise.Copyright: © 2022 Journal of Research in Medical Sciences.
