In individuals with chronic kidney disease, walking does not appear to increase any burden on the kidney, but can improve the nutritional and clinical parameters of the individuals, and reduce inflammation.

In March 2019 researchers from China published the results of their study to assess the effect of the daily walking number on clinical, inflammatory and nutritional profiles for individuals, with chronic kidney disease. A total of 90 individuals, not undergoing dialysis, were involved in the study. The individuals were divided into three equal groups, to undertake a daily walk which consisted of (1) less than 5,000 steps, (2) between 5,000 and 9,999 steps; and (3) over 10,000 steps. The individuals continued to receive basic treatment, with blood tests being undertaken and nutritional information collected. A total of 87 individuals with chronic kidney disease completed the study, with group (2) losing one individual and group (3) losing two individuals during the three months of the study. Results showed that there were no significant changes on blood lipids, uric acid and parathyroid hormone in any of the three groups. However, in group (3) haemoglobin and ferritin levels and transferrin saturation were found to be significantly increased whilst C-reactive protein and interleukin-6 (inflammatory markers) were seen to be significantly decreased. For the nutritional parameters, there were increasing levels of albumin and pre-albumin in all three groups, with the increases being in line with the number of steps walked. There were no significant changes on body mass index and upper arm skinfold thickness.
