Therapeutic benefits of exercise training for hemodialysis patients.

Abstract

Twenty-five hemodialysis patients were randomized into comparable exercising (E, N = 14) and sedentary control (N = 11) groups. After baseline testing, training was 3 to 5 times weekly for a mean of 12 +/- 4 (SD) months. Maximal aerobic capacity increased 21% (P less than 0.01), and the durations for the graded exercise stress test improved 19% (P less than 0.01) in E, but did not change in controls (8 +/- 4 months). Declining blood pressures in 8 hypertensive E led to reductions in antihypertensive medications; no changes occurred in 9 hypertensive controls. Exercise lowered plasma total triglyceride levels 33% (280 +/- 258 to 175 +/- 95 mg/dl; P less than 0.01), but no change occurred in total and low-density lipoprotein cholesterol concentrations. High-density lipoprotein cholesterol levels rose 16% in E (31 +/- 9 to 36 +/- 12 mg/dl; P less than 0.02), but did not change in controls. An increase in the affinity of insulin for receptors on mononuclear cells was associated with a 20% decrease in fasting plasma insulin levels (24 +/- 7 to 19 +/- 2 microU/ml, N = 8; P less than 0.05) and a 42% improvement in glucose disappearance rates (1.9 +/- 1.0 to 2.6 +/- 1.2% per min, N = 6) in E. There were no changes in the body weights or diets of the patients. A 27% increase in red blood cell mass (P less than 0.02) with no change in plasma volume resulted in a 27% increase in hematocrit (24 +/- 3% to 31 +/- 5%, P less than 0.01) and a 20% increase in hemoglobin (8 +/- 1 to 10 +/- 2 g/dl; P less than 0.01) in E.(ABSTRACT TRUNCATED AT 250 WORDS).
