Abstract

Introduction: We evaluated the effect of intradialytic concurrent (resistance-endurance) training combined with melatonin (MEL) supplementation on functional capacity, muscle strength, postural balance, and quality of life (QoL) in hemodialysis (HD) patients.

Methods: Thirty-three HD patients were randomized into three groups: Exercise (EX)-MEL (n = 11); EX-Placebo (PLA) (n = 11) and Control (C)-PLA (n = 11). Participants included in the EX-MEL and EX-PLA groups were submitted to concurrent training for 12 weeks.

Results: EX-MEL and EX-PLA improved functional capacity, muscle strength, QoL, and postural balance parameters in eyes open and eyes closed conditions. Parameters of postural balance in the dual task condition were improved only in EX-MEL. EX-MEL induced better results in some domains of QoL compared with EX-PLA.

Conclusion: Intradialytic concurrent training induced beneficial effects on physical function, muscle strength, postural balance, and QoL in HD patients. MEL supplementation combined with intradialytic exercise lead to better improvements in postural balance and QoL.
