Individuals with CKD (both predialysis and ESRD) may be at greater risk of sarcopenia given the combined reductions in physical function, skeletal muscle performance and skeletal muscle mass.~Study include sixty male patients on hemodialysis for 1-3 years aged from 45 to 55 years old selected from hemodialysis unit at National Institute of Urology and Nephrology. Before starting treatment , patients will fill consent form and the study aims and procedure will be explained to each patient . study include Sixty male patients on hemodialysis for 1-3 years aged from 45 to 55 years old selected from hemodialysis unit at National Institute of Urology and Nephrology. Patients will be assigned randomly by computerized block randomization into two groups:Group (A): 30 patients will participate in 8 weeks of aerobic exercise in the form of high intensity interval training (HIIT) intradialytic pedaling exercise plus hemodialysis (3 sessions per week).Group (B): 30 patients will participate in 8 weeks of aerobic exercise in the form of moderate intensity continous training (MICT) intradialytic pedaling exercise plus hemodialysis (3 sessions per week) Karvonen formula will be used to calculate training heart rate THR= RHR+ (HRmax - RHR) 65%-80% AS HRmax = 220-Age patients of HIIT will perform aerobic exercise in the form of leg pedaling exercise in semi-supine position using leg ergometer at high intensity 85%-95% of HRpeak with 4 min of active breaks at an intensity of 60%-70% of HRpeak. . Exercise will be done at the first 2 hours of dialysis (to avoid dialysis hypotension episodes).~patients of MICT will perform aerobic exercise in the form of leg pedaling exercise in semi-supine position using leg ergometer at moderate intensity 50%-60% of HRpeak . Exercise will be done at the first 2 hours of dialysis (to avoid dialysis hypotension episodes).~primary and secondary variables will be measured before starting treatment and after completion (after 2 months )
The goal of this study is to find out the effect of interval versus continous intradialytic training on muscle quality index and functional capacity in Hemodialysis patients. The main question it aims to answer is:~Does interval versus continous intradialytic training have an effect on muscle quality index and functional capacity in hemodialysis patients? Patients will be assigned randomly by computerized block randomization into two groups:Group (A): 30 patients will participate in 8 weeks of aerobic exercise in the form of high intensity interval training (HIIT) intradialytic pedaling exercise plus hemodialysis (3 sessions per week).Group (B): 30 patients will participate in 8 weeks of aerobic exercise in the form of moderate intensity continous training (MICT) intradialytic pedaling exercise plus hemodialysis (3 sessions per week) . primary and secondary variables will be measured before starting treatment and after completion (after 2 months )
