This study evaluated the effects of ingesting sodium bicarbonate (NaHCO3) or caffeine individually or in combination on high-intensity cycling capacity. In a counterbalanced, crossover design, 13 healthy, noncycling trained males (age: 21 ± 3 years, height: 178 ± 6 cm, body mass: 76 ± 12 kg, peak power output (Wpeak): 230 ± 34 W, peak oxygen uptake: 46 ± 8 mL·kg(-1)·min(-1)) performed a graded ...

The potential ergogenic effect of nutritional supplements depends on their dosage and the type exercise executed. Aiming at reviewing research literature regarding sport utilized in judo order to improve performance, a search was performed following databases: Dialnet, PubMed, Scielo, Scopus SportDiscus. A total 11 articles met inclusion criteria were selected. Evidence revised indicates that s...

Sodium-bicarbonate cotransporters are homologous membrane proteins mediating the electrogenic or electroneutral transport of sodium and bicarbonate. Of the functionally characterized sodium-bicarbonate cotransporters (NBC), NBC1 proteins are known to be electrogenic. Here we report the cloning and functional characterization of NBC4c, a new splice variant of the NBC4 gene. At the amino acid lev...

Sodium fluxes across the isolated rabbit corneal endothelium were measured as a function of ambient pH and bicarbonate concentrations. At pH 7, the net sodium flux (J endo str net) was effectively obliterated at all bicarbonate concentrations, relative to controls at pH 7.5. At pH 8, the net sodium flux was obliterated at 5 mM bicarbonate, was unchanged at 25 mM bicarbonate, and was enhanced at...

PURPOSE This in vitro experiment studied the effects of sodium bicarbonate and hydrogen peroxide on the cariogenic bacteria Streptococcus mutans through analysis with a spectrophotometer. METHODS The growth of S. mutans was analyzed using seven different environments. Twelve wells in each of the seven rows of a multi-well plate were used to incubate the test materials. In combinations of 10 m...

abstract background: sodium bicarbonate serum therapy is used for compensation bicarbonate lost and increasing blood ph in metabolic acidosis caused by severe anemia in patient with glucose-6-phosphate dehydrogenase (g6pd) deficiency. the aim of present study was comparison the effect of serum therapy using two different serums (serum with bicarbonate and without bicarbonate) on some renal and ...

This study documents the development of alkalosis in patients returning to caloric intake after a period of starvation and investigates the mechanisms responsible for this metabolic alteration. We studied the acid-base status, bicarbonate reabsorption, acid excretion, and sodium metabolism during fasting and glucose refeeding in 19 patients receiving sodium supplements. Metabolic alkalosis deve...

Major uses Sodium bicarbonate is a main constituent of baking soda/powder. Baking powder is composed of 30% of sodium bicarbonate, with cornstarch, sodium aluminium sulfate, calcium acid phosphate, and calcium sulfate [1]. Sodium bicarbonate may be an ingredient of folk remedies containing turpentine, castor oil, lemon and sugar. It is also added to mouthwashes and dentifrices to prevent dental...

Bicarbonate reabsorption in the thick ascending limb of Henle's loop was examined by studies of free-water clearance (CH2O) and free-water reabsorption (TcH2O). During maximal water diuresis in the dog, CH2O/GFR was taken as an indes of sodium reabsorption in, and urine flow (V/GFR) as an index of delivery of filtrate to, this scarbonate, infusion of a nonreabsorbable solute (hypotonic mannitol...
