Influence of Beverage Temperature on Palatability and Fluid Ingestion During Endurance Exercise: a systematic review.

BACKGROUND. Beverage palatability is known to influence fluid consumption during exercise and may positively influence hydration status and help to prevent fatigue, heat illness and decreased performance. PURPOSE: The aims of this review were to evaluate the effect of beverage temperature on fluid intake during exercise and investigate the influence of beverage temperature on palatability. [...]

Saliva indices track hypohydration during 48h of fluid restriction or combined fluid andenergy restriction.

OBJECTIVE: To investigate whether unstimulated whole saliva flow rate (UFR) and osmolality (Sosm) track changes in hydration status during 48h of restricted fluid intake (RF) or combined fluid and energy restriction (RF+RE). Following the 48h periods, UFR and Sosm were assessed after acute exercise dehydration and rehydration. DESIGN: Thirteen healthy males completed three trials in a randomised order: control (CON) where participants received their estimated energy (12,154+/-230kJ/d: mean+/-S.E.M) and fluid (3912+/-140ml/d) [...]

Physical signs of dehydration in the elderly.

Objective Dehydration is a common condition and frequent cause of hospitalization in older people, despite the caregiver's high attention in attempt to avoid its occurrence. In this study, various physical signs were examined as clinical signs of dehydration in elderly. Methods A prospective observational study was conducted in an acute care teaching hospital. Consecutive elderly [...]

Saliva parameters as potential indices of hydratio status during acute dehydration.

PURPOSE: Firstly, to identify whether saliva flow rate, osmolality, and total protein are potential markers of hydration, we compared changes in these parameters with changes in plasma osmolality during progressive dehydration. Secondly, we compared the sensitivity of saliva parameters to track hydration changes with the sensitivity of urine osmolality. Thirdly, to test the hypothesis thatdehydration, rather than neuroendocrine regulation, is responsible for the decrease in saliva flow rate during prolonged [...]

Effects of hydration and water deprivation on blood viscosity during a soccer game in sickle cell trait carriers.

The present study compared the changes in blood viscosity, hydration status, body temperature and heart rate between a group of sickle cell trait (SCT) carriers and a control (Cont) group before and after a soccer game performed in two conditions: one with water offered ad libitum (hydration condition; Hyd) and the other one without water [...]

Hydration and independence in activities of daily living in people with multiple sclerosis: a pilot investigation.

We investigated whether an athlete's self-chosen nutrition strategy (A), compared with a scientifically determined one (S), led to an improved endurance performance in a laboratory time trial after an endurance exercise. S consisted of about 1000 mL·h(-1) fluid, in portions of 250 mL every 15 min, 0.5 g sodium·L(-1), 60 g glucose·h(-1), 30 g fructose·h(-1), and 5 mg caffeine·kg body mass(-1). Eighteen [...]

Bioelectrical impedance analysis in the assessment of hydration status in peritoneal dialysis patients.

Objective: Assessment of fluid status in chronic peritoneal dialysis (PD) patients is complex. Clinical evaluation based solely on body weight, blood pressure, volume of ultrafiltration (UF) and peripheral edema is insufficient. A non-invasive test, bioelectrical impedance analysis (BIA) might be of potential benefit. Aim: To test whether BIA correlates with other ancillary markers of extracellular [...]

Problem: thirst, drinking behavior, and involuntary dehydration.

The phenomenon of involuntary dehydration, the delay in full restoration of a body water deficit by drinking, has been described extensively but relatively little is known about its physiological mechanism. It occurs primarily in humans when they are exposed to various stresses including exercise, environmental heat and cold, altitude, water immersion, dehydration, and perhaps microgravity, singly and in various [...]

Assessment of fluid status in peritoneal dialysis.

Fluid management is recognized as a basic component of management of patients on dialysis. Fluid overload is an important adverse factor in patient outcomes, and the negative effects of fluid depletion, including on residual renal function, are aIso increasingly being recognized. The complexities of fluid distribution in renal failure need to be understood to inform [...]

Application of multifrequency bioelectrical impedance analysis method for the detection of dehydration status in professional divers.

BACKGROUND AND OBJECTIVE. The level of dehydration has been known to be a predisposing factor for the development of decompression sickness in divers. The aim of this study was to determine the level of dehydration in divers who dove with heliox and to determine whether the source of this dehydration was intracellular and/or extracellular by [...]
