Article Synopsis
  • High-intensity exercise reduces renal blood flow (RBF) in both younger and older men, but the effects differ between the two age groups.
  • While younger individuals' RBF levels return to baseline 60 minutes post-exercise, older individuals show a significant decrease in RBF compared to their pre-exercise levels.
  • The study suggests that aging may negatively affect the kidneys' ability to recover from the hemodynamic stress of high-intensity exercise.

Liver fibrosis might be linked to the prevalence of chronic kidney disease (CKD). However, there is little information about the association between liver fibrosis and decreased kidney function in middle-aged and older subjects. We aimed to evaluate the influence of liver fibrosis on the incidence or prevalence of CKD stage 3-5 in a retrospective cross-sectional study (Study 1, = 806) and a 6-year longitudinal study (Study 2, = 380) of middle-aged and older subjects.

Background: Acute exercise reduces renal blood flow (RBF). However, the effect of exercise intensity on RBF in patients with chronic kidney disease (CKD) stage 2 is not known. We investigated the association between RBF and exercise intensity in patients with CKD stage 2 using pulsed Doppler ultrasonography.
