Clinical Trial Summary

This study aims at evaluating, in chronic kidney disease patients on dialysis, the effect of acute per- or pre-dialytic physical exercise on regional myocardial function and myocardial stunning, blood viscosity, arterial stiffness, variability of sinus rhythm, dialysis efficacy, inflammation, mineral and bone disorders, myokines and cardiac remodeling markers.

Intervention

Procedure:
• Dialysis without physical exercise
Hemodialysis control condition
• Dialysis with pre-dialytic physical exercise
Patients will pedal for 30 minutes using a ergometer directly attached to the dialysis bed. The exercise will be performed 60 minutes before connection to hemodialysis.
• Dialysis with per-dialytic physical exercise
Patients will pedal for 30 minutes using a ergometer directly attached to the dialysis bed. The exercise will start 30 minutes after the start of dialysis.
