Effects of Intradialytic Exercise on Muscle Oxygenation and Dialysis Adequacy

Brief summary (registry, in English)

This randomized controlled trial will evaluate the effects of a 12-week intradialytic combined exercise program, consisting of aerobic and resistance training, in patients with stage 5 chronic kidney disease receiving maintenance hemodialysis. Sarcopenia, a progressive loss of muscle mass and strength, is common in this population due to chronic disease burden and the sedentary nature of dialysis sessions. The intervention group will perform structured exercise three times per week during the first two hours of dialysis, while the control group will continue routine dialysis care without exercise. The primary aim is to investigate whether intradialytic exercise can improve dialysis adequacy and muscle oxygenation, and reduce sarcopenia severity. Secondary objectives include evaluating changes in physical performance, muscle strength, fatigue levels, and health-related quality of life. Approximately 40 participants will be randomized into intervention and control groups. Outcomes will be assessed through clinical measurements, functional tests, and patient-reported questionnaires before and after the intervention period.
