Amino Acids Supplementation and Exercise Intervention in Hemodialysis Patients

The goal of this randomized clinical trial is to observe the effect of Amino acids (AAs)supplementation and exercises in haemodialysis patients . The main question it aims to answer is : Does AAs supplementation and regular exercises have an effect on the muscle mass and function in haemodialysis patients ? Participants will receive daily a total of six tablets of amino acids supplementation divided into three doses. And some Participants will also be asked to do intradialytic exercise. Researchers will compare the effects of these interventions on the muscle mass and fatigue, among four groups: 1. A group that will be only taking AAs supplementation 2. A group taking AAs supplementation along with intradialytic exercise 3. A group only performing intradialytic exercise 4. A passive control group This will be monitored through BMI, anthropometric measures, Musculoskeletal ultrasound assessment of the quadriceps muscle , fatigue questionnaires and sit and stand test.
