Dialysis patients get stronger and sleep better with In-Chair exercise program
NCT ID NCT07447375
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a 12-week supervised exercise program done during dialysis can improve muscle mass, strength, sleep, and quality of life in adults over 40 with chronic kidney disease. Participants are randomly assigned to either exercise during the first 90 minutes of dialysis or receive standard care. The goal is to see if adding exercise to routine care helps reduce sarcopenia (muscle loss) and improve overall well-being.

Inclusion Criteria: * Subjects currently enrolled in a Chronic Hemodialysis Unit. * Patients who have been on hemodialysis treatment for more than 3 months. * Subjects aged 40 years or older. * Hemoglobin levels greater than 10 mg/dl. * Ability to perform physical fitness assessment tests or dynamometry. * Willingness and ability to provide signed informed consent Exclusion Criteria: * Presence of intradialytic instability. * Medical conditions where exercise is contraindicated: active infectious process, neoplasms, uncontrolled arrhythmias, or left ventricular dysfunction (EF \< 35%). * Musculoskeletal or respiratory alterations that worsen with exercise. * Lower limb amputation without a prosthesis. * Cerebrovascular disease (stroke with sequelae or transient ischemic attacks within the previous 6 weeks). * Uncontrolled hypertension (Systolic BP \> 200 mmHg or Diastolic BP \> 120 mmHg). * Unstable angina (at rest or during exercise) or history of coronary bypass/ischemic heart disease within the previous 6 weeks. * Diabetes mellitus with severe decompensation (blood glucose \> 300 mg/dl). * Dialysis-related hypotension (mean blood pressure \< 90/70 mmHg). * Psychiatric or cognitive alterations that prevent collaboration with muscle training programs. * Presence of an arteriovenous fistula in a lower limb. * Motor neurological injury causing dysfunction that prevents the application of the strength protocol. * Hospitalization within the 3 months prior to the study. * Lack of cooperation (defined as failing to attend more than 25% of sessions) or inability to understand the treatment.
