Abstract

BACKGROUND: Physical exercise may be an adjunctive therapy for individuals with chronic kidney diseases (CKD) as this pathological condition has been associated with multiple comorbidities including hypertension and diabetes mellitus. However, little is known about the acute effects of exercise on renal function in patients with CKD at different stages. AIM To investigate the acute effects of aerobic exercise on renal function in patients at different stages of non-dialysis CKD. METHODS: Thirty-three subjects were divided into three groups as follows: i) patients in stages 1 and 2 (CKD1-2; n= 11); ii) stages 3 and 4 (CKD3-4; n= 11); iii) healthy individuals (CON; n= 11). Individuals performed 30 minutes of exercise on a treadmill in an intensity corresponding to the ventilatory anaerobic threshold (VAT) (%VO2peak= 60 ± 8). Blood samples were collected before, immediately after exercise, 30 and 60 minutes after exercise and urine samples were collected before, 30, 60 and 90 minutes after exercise for creatinine and albuminuria assessments. Glomerular Filtration Rate (GFR) was estimated using the creatinine clearance (GFRCr-Cl) and estimated using the CKD-EPI 2009 equation (eGFR). RESULTS: Immediately after exercise, GFRCr-Cl and eGFR did not change significantly in all groups (all p > 0.05). Although both groups of CKD patients have shown increased albuminuria immediately after exercise, differences were not significant (p > 0.05). No change in albuminuria was detected in the control group throughout the protocol (p > 0.05). CONCLUSION: The results suggest that a 30-min moderate intensity aerobic exercise bout does not impair renal function in patients with CKD. Thus, these data support the notion that exercise training can be a safe therapeutic tool in the management of CKD (AU)
