Exercise training ameliorates progressive renal disease in rats with subtotal nephrectomy

Kidney Int. 1987 Dec;32(6):815-20. doi: 10.1038/ki.1987.281.


To determine the effect of chronic exercise training on renal function in animals with moderate renal insufficiency, rats with 75% renal ablation were either exercise trained by swimming for two months or remained sedentary. Glomerular filtration rate was significantly higher in trained (1.89 +/- 0.07 ml/min) than in sedentary rats (1.52 +/- 0.11 ml/min). No change was observed in renal blood flow or the degree of hypertension. Proteinuria was reduced in trained (13.6 +/- 4.9 mg/24 hr) compared to sedentary animals (33.5 +/- 9.2 mg/24 hr). The degree of glomerulosclerosis was much less prominent in trained animals. Plasma, low-density lipoprotein cholesterol-levels and total triglycerides were reduced in trained compared to sedentary rats. This study suggests that chronic exercise training ameliorates the progression of renal disease and improves plasma lipids in rats with moderate renal insufficiency. The mechanism for this improvement in renal function appears to be independent of the influence of systemic blood pressure.
