Objective: to evaluate the effects of an intradialytic resistance exercise program on sleep quality and cardiac autonomic modulation in hemodialysis patients. Method: non-randomized clinical trial, carried out between February 2019 and October 2020, with 52 individuals with chronic renal failure on dialysis, divided into an intervention group (IG; n=32) and a control group (CG; n=20). The IG performed 12 weeks of intradialytic physical training, three times a week. Indices of sleep quality and cardiac autonomic modulation were measured. Results: there was an increase in the standard deviation indices of beat-to-beat intervals (SDNN) (ms) (p=0.0004), square root of the mean square of adjacent beat-to-beat intervals (RMSSD) (ms) (p<0. 0001), standard deviation 1 (SD1) (ms) (p=0.03) and standard deviation 1/standard deviation 2 (SD1/SD2) ratio (p=0.0003). There was no improvement in sleep quality. Conclusion: Intradialytic resistance exercise is able to improve cardiac autonomic modulation in patients with chronic kidney disease.
