Difference Between Interval and Continous Intradialytic Exercise on Functional Capacity in Hemodialysis Patient

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 )
