Cardiorespiratory fitness: a comparison between children with renal transplantation and children with congenital solitary functioning kidney

Children with end-stage renal disease are known to have a cardiorespiratory fitness significantly reduced. This isconsidered to be an independent index predictive of mortality mainly due to cardiovascular accidents. The effectsof renal transplantation on cardiorespiratory fitness are incompletely known. We compared the maximal oxygenuptake (VO2 max) of children with a functioning renal transplant with that of children with congenital solitaryfunctioning kidney, taking into consideration also the amount of weekly sport activity
