The purpose of the present study was to examine the influence of submaximal aerobic exercise duration on simple and complex cognitive performance. Eight well-trained male subjects agreed to participate in this study (trial group). A control group of eight regularly trained male subjects was included for comparative purposes. For the trial group, the experiment involved [...]
Disorders of sodium and water homeostasis are among the most commonly encountered disturbances in the critical care setting, because many disease states cause defects in the complex mechanisms that control the intake and output of water and solute. Because body water is the primary determinant of extracellular fluid osmolality, disorders of body water balance can [...]
To determine the effectiveness of 3 commonly used beverages in restoring fluid and electrolyte balance, 8 volunteers dehydrated by 1.94% +/- 0.17% of body mass by intermittent exercise in the heat, then ingested a carbohydrate-electrolyte solution (Gatorade), carbonated water/apple-juice mixture (Apfelschorle), and San Benedetto mineral water in a volume equal to 150% body-mass loss. These [...]
Water balance in the elderly is critical in preventing tissue dehydration. Negative water balance, occurring when more water is lost than is retained, results in a severe decrease in all secretions. This "drying out" of tissues and organs, including muscles and joints, may lead to premature aging. Xerostomia is a major cause of denture discomfort [...]

OBJECTIVE: To describe associations between hydration status and dietary behaviour in children, as current research indicates that hydration status is influenced by nutrition vice versa, hydration status may influence dietary behaviour. DESIGN: Cross-sectional analyses of data from the Dortmund Nutritional and Anthropometric Longitudinally Designed Study, (DONALD) using 24-h urine samples to determine the hydration status [...]

To evaluate the relative utility of clinical and laboratory parameters of dehydration in children for predicting the magnitude of percent less of body weight (PLBW), we studied 97 children who required intravenous fluids for acute dehydration. After a complete history and physical examination, the managing physician made a clinical estimation of dehydration for each child, [...]
