Consumption of sodium bicarbonate (300 mg/kg 1-2 h before exercise) can temporarily increase blood bicarbonate concentrations, enhancing extracellular buffering of hydrogen ions which accumulate and efflux from the working muscle. Such 'bicarbonate loading' provides an ergogenic strategy for sporting events involving high rates of anaerobic glycolysis which are otherwise limited by the body's c...

BACKGROUND Volume supplementation by saline infusion combined with N-acetylcysteine (NAC) represents an effective strategy to prevent contrast agent-induced nephrotoxicity (CIN). Preliminary data support the concept that sodium bicarbonate and ascorbic acid also may be effective in preventing CIN. METHODS AND RESULTS Three hundred twenty-six consecutive patients with chronic kidney disease, r...

The effects of varying recovery modes and the influence of preexercise sodium bicarbonate and carbohydrate ingestion on repeated high intensity performance, acid-base response, and recovery were analyzed in 12 well-trained males. They completed three repeated high intensity running bouts to exhaustion with intervening recovery periods of 25 min under the following conditions: sodium bicarbonate...

BACKGROUND Contrast-induced acute kidney injury [contrast-induced nephropathy (CIN)] is one of the major causes of hospital-acquired acute renal failure. Volume supplementation is the most effective strategy to prevent acute renal failure caused by contrast; but the effects of sodium bicarbonate regimens are unknown in CIN prevention. The aim of this survey is to compare the efficacy of hydrati...

BACKGROUND There is increasing evidence of the benefit of regular physical exercise in a number of long-term conditions including chronic kidney disease (CKD). In CKD, this evidence has mostly come from studies in end stage patients receiving regular dialysis. There is little evidence in pre-dialysis patients with CKD Stages 4 and 5. METHODS A prospective study compared the benefits of 6 mont...

Biochemical control. Renal function is assessed from plasma creatinine and, ideally, a yearly isotopic measurement of glomerular filtration rate (GFR). Until the patient has stopped growing, GFR can be estimated using the Schwartz formula (height in cm x 40/creatinine mmol/l). GFR increases rapidly in the first two years of life to adult values, provided that it is adjusted for body surface are...
