Arms of the Study
Arm 1
Arm 2
Experimental
Active Comparator
Exercise group
Control group
Patients will remain in supine position for 5 minutes to measure their vascular caliber of the AVF by echography. After, will be instructed to perform 30 minutes on stationary bicycle (Model Monark). The AVF vascular caliber will be measured during aerobic exercise. Because it is a cross-over trial, participants will perform the other arm after 7 days.
The patients will perform 30 minutes of rest in a chair and the measurements will be performed in the same moments established by the exercise group. Because it is a cross-over trial, participants will perform the other arm after 7 days.
