This study aimed to compare the physiologic effects of regular water consumption to those of electrolyte drink consumption in exercise capacity and recovery after exhaustive exercise. The participants were 10 healthy young men who exercised on a treadmill before and after receiving regular water and an electrolyte drink (3RINK) four weeks later. A 250-mL fluid volume was ingested 30 min before exercise and immediately after. Body composition, water metabolizing hormones, and body electrolytes were analyzed at rest (R), immediately after exercise (P0), and 1 h after exercise (P1). Moreover, serum lactic acid levels were measured to determine recovery. Total body water, intracellular, and extracellular water levels were higher after consuming 3RINK at P0 than at R. There was no interaction effect between the types of fluids and antidiuretic hormone, aldosterone, and renin levels. Hematocrit levels showed an interaction effect between the type of fluid and period. Sodium levels were significantly different between the different types of fluids at P0 and P1. Finally, an interaction effect was noted between each type of fluid and serum lactate levels. Thus, 3RINK intake before and after exhaustive exercise increased body capacity to retain water, improved exercise ability, and reduced exercise-related fatigue.

1. Total body water (TBW) estimated by tritium and extracellular water (ECW) estimated by sodium thiosulfate has been measured in 19 cases of kwashiorkor before and immediately after loss of edema. 2. The TBW as a percentage of body weight was increased but changed relatively little as edema was lost (70%-69%). 3. The ECW (thiosulfate space) showed a significant decrease with loss of edema (33%-26%). 4. The intracellular water (TBW-ECW) increased markedly (37%-43%). 5. These results suggest that the edema of kwashiorkor is a phenomenon of mal-distribution of the excess body water between the body compartments and not only an excess accumulation of body water per se.

Normal values for both total body water and extracellular water have been determined in 86 premature infants aged 1 to 90 days and weighing 940 to 2,435 gm, with use of the techniques of deuterium oxide and bromide dilution. Nine full-term infants aged 1 to 6 days and weighing 2,590 to 4,985 gm were similarly studied. Nine infants with the respiratory distress syndrome and eight infants of toxemic mothers studied in the first 24 hours of life showed no significant difference in their body water compartments in comparison to a control group of normal infants matched for age and weight. Seven infants of diabetic mothers studied in the first 24 hours of life showed a significant decrease in total body water, expressed as percentage of body weight, with a normal intracellular to extracellular water ratio. These data indirectly support other evidence that there is an increase in body fat in these infants at birth. See Table in the PDF file

Knowledge of patient fluid distribution would be useful clinically. Both single-frequency (SF) and impedance modeling approaches are proposed. The high intercorrelation between body water compartments makes determining the best approach difficult. This study was conducted to evaluate the merits of an SF approach. Mathematical simulation was performed to determine the effect of tissue change on resistance and reactance. Dilution results were reanalyzed, and resistance and parallel reactance were used to predict the intracellular water for two groups. Results indicated that the amount of intracellular and extracellular water conduction at any SF can vary with tissue change, and reactance at any SF is affected by all tissue parameters. Modeling provided a good prediction of dilution intracellular and extracellular water, but an SF method did not. Intracellular, extracellular, and total body water were equally predicted at all frequencies by SF resistance and parallel reactance. Extracellular and intracellular water are best measured through modeling, because only at the zero and infinite frequencies are the results sensitive only to extracellular and intracellular water. At all other frequencies there are other effects.

Context Dehydration is assumed to be a major adverse effect associated with rapid loss of body mass for competing in a lower weight class in combat sports. However, the effects of such weight cutting on body fluid balance in a real-life setting are unknown. Objective To examine the effects of 5% or greater loss of body mass within a few days before competition on body water, blood volume, and plasma volume in elite amateur boxers. Design Case-control study. Setting Sports medicine laboratory. Patients or Other Participants Seventeen male boxers (age = 19.2 ± 2.9 years, height = 175.1 ± 7.0 cm, mass = 65.6 ± 9.2 kg) were assigned to the weight-loss group (WLG; n = 10) or the control group (CON; n = 7). Intervention(s) The WLG reduced body mass by restricting fluid and food and inducing excessive sweat loss by adhering to individual methods. The CON participated in their usual precompetition training. Main Outcome Measure(s) During an ordinary training period (t-1), 2 days before competition (t-2), and 1 week after competition (t-3), we performed bioelectrical impedance measurements; calculated total body water, intracellular water, and extracellular water; and estimated total hemoglobin mass (tHbmass), blood volume, and plasma volume by the CO-rebreathing method. Results In the WLG, the loss of body mass (5.6% ± 1.7%) led to decreases in total body water (6.0% ± 0.9%), extracellular water (12.4% ± 7.6%), tHbmass (5.3% ± 3.8%), blood volume (7.6% ± 2.1%; P < .001), and plasma volume (8.6% ± 3.9%). The intracellular water did not change (P > .05). At t-3, total body water, extracellular water, and plasma volume had returned to near baseline values, but tHbmass and blood volume still were less than baseline values (P < .05). In CON, we found no changes (P > .05). Conclusions In a real-life setting, the loss of approximately 6% body mass within 5 days induced hypohydration, which became evident by the decreases in body water and plasma volume. The reduction in tHbmass was a surprising observation that needs further investigation.

First Year Of Life

During growth of infants and children, certain characteristic changes are found. A rapid decrease of the relative volumes of total body water and of extracellular water occurs during the first year of life, followed by a smaller decrease of volume of extracellular water later in childhood. At the same time an increased heterogeneity of the extracellular water takes place. On the other hand, the volume of intracellular water increases a little during the first months of life and remains more or less constant from then on. Formulas and nomograms from which these body water compartments can be predicted are presented. Finally, data on the corresponding changes in the total body water and in body specific gravity are discussed.

Volumes Of Distribution

The relationship between the volume of distribution, assessed according to the two-compartmental pharmacokinetic model, and extracellular water estimated by bioimpedance was studied in mechanically ventilated patients with sepsis and capillary leak. A prospective observational study was performed in a twenty-bed general intensive care unit in the university hospital. Patients received either vancomycin (n=16) or netilmicin (n=12) for more than 48 hours. Those with ascites, pleural effusion, on renal replacement therapy or with haemodynamic instability were excluded. Serum concentrations of drugs were taken for pharmacokinetic analysis before, 1 hour and 4 hours after the 30 minute infusion. Bioimpedance measurement was performed at the time of the third sampling. The protocol was repeated after 24 hours. Fluid balance during the 24 hour interval was recorded. Extracellular water was increased and represented 45.6 to 46.6% of total body water. Fluid balance correlated with the change of extracellular water (r=0.82, P<0.0001) and total body water (r=0.74, P<0.0001). Volumes of distribution of vancomycin (0.677±0.339 l/kg) and netilmicin (0.505±0.172 l/kg) were increased compared to normal values. A correlation was demonstrated between volume of distribution (Vdarea) of vancomycin and extra cellular water/total body ratio (r=0.70, P<0.0001). The central compartment distribution volume (V1) of netilmicin correlated with extracellular water/total body water ratio (r=0.60, P<0.003). Serum concentrations above the recommended therapeutic range were detected in 81.2% of patients on vancomycin and in 50% of patients on netilmicin. Increased volumes of distribution can be estimated by the bioimpedance measurements but are not associated with requirements for higher dosage of the glycopeptide or aminoglycoside antibiotics.
