Creatine and intradialytic exercise in people on hemodialysis
Official title: Effect of an Intradialytic Physical Exercise Programme Supplemented With Creatine Monohydrate on Body Composition, Biochemical Parameters and Functionality in Patients With Stage 5 Chronic Kidney Disease Undergoing Haemodialysis: Phase II Double-blind Randomised Clinical Trial.
Run by Universidad de Colima · NCT07666815 · Data updated 2026-11-12
The study tests whether taking creatine and doing in-dialysis exercise can improve body composition and physical function in adults with CKD on maintenance hemodialysis.

Is this trial a fit for you?
✓Likely a good fit
Adults on thrice-weekly maintenance hemodialysis for CKD, within two years of starting dialysis, able to consent and participate in an exercise program.
✕Probably not a fit
Patients unable to perform physical exercise or with conditions prohibiting creatine use may not benefit.

What this trial studies
This randomized, double-blind trial compares four groups to assess the independent and combined effects of creatine monohydrate supplementation and an intradialytic exercise program over 8 weeks in adults undergoing thrice-weekly hemodialysis. Participants are assigned to standard care, creatine only, intradialytic exercise only, or creatine plus exercise. Outcomes include body composition, biochemical markers, and measures of functional capacity at baseline and after 8 weeks. The study aims to inform strategies to improve nutritional status, physical function, and overall health in CKD patients receiving dialysis. Safety monitoring includes tracking adverse events related to creatine and exercise tolerance.
Why it matters
Potential benefit: If successful, patients may experience improved physical function and nutritional status during routine dialysis.
How similar studies have gone: Prior research in similar populations suggests feasibility of exercise and supplementation but combined effects in this exact setup are not fully established.
