Effect of Intradialytic Resistance Versus Aerobic Exercise on Cardiovascular System in Patients on Regular Hemodialysis

The participants receive hemodialysis for 4 hours, 3 times per week

"The participants will receive intradialytic resistive exercise for 12 weeks (3 sessions/ week).~Duration: 30 minutes during the first 2 hours of each dialysis session in a recumbent position or seated position.~Time of session: The program starts with a warm-up phase which is 3:5 minutes in the form of light aerobic and stretching exercises for big muscles and ends with a cooling down phase which is 3:5 in the form of light aerobic exercise.~The resistance exercises include exercises for the big muscles of only the Lower Limbs (LL) muscles of single and multiple-joint which are:1- Knee extensors, 2- Knee flexors, 3- Hip flexors, 4- Hip abductors and adductors. using sandbags of different weights. Sandbag weights are placed on the distal third of the tibia for LL exercises.~Intensity: On the Borg's Scale of Perceived Exertion, which will be measured every 5 minutes during exercise."

"Patients with chronic kidney disease will receive an intradialytic aerobic exercise for 12 weeks (3 sessions/ week).~Duration: 30 minutes during the first 2 hours of each dialysis session using a stationary bicycle ergometer in a supine position or seated position.~Time of session: The warming up and the cooling down phase consists of 5:10 minutes of slow Pedaling. the main exercise phase consisted of 20 minutes of cycling.~Intensity: The use of the Borg's Scale of Perceived Exertion (RPE) scale enables the intensity of the exercise to be adapted According to the tolerance of each patient.~The use of the RPE scale enables the intensity of the exercise to be adapted According to the tolerance of each patient, the aim was to obtain between 11 light And 14 somewhat hard."
