BODY FLUID BALANCE IN DEHYDRATED HEALTHY OLDER MEN: THIRST AND RENAL OSMOREGULATION
We examined osmotic control of thirst and free water clearance in healthy older (65+, n = 10) and younger (Y, n = 6) subjects during a 3-h rehydration period after an approximately 2.4% decrease in body weight. Plasma volume (PV), plasma osmolality (Posm), renal function, and thirst were measured before and after dehydration and during [...]
HYPERHYDRATION: THERMOREGULATORY EFFECTS DURING COMPENSABLE EXERCISE-HEAT STRESS
This study examined the effects of hyperhydration on thermoregulatory responses during compensable exercise-heat stress. The general approach was to determine whether 1-h preexercise hyperhydration [29. 1 ml/kg lean body mass; with or without glycerol (1.2 g/kg lean body mass)] would improve sweating responses and reduce core temperature during exercise. During these experiments, the evaporative heat [...]
INGESTION OF COLD FLUIDS: RELATED TO ONSET OF ARRHYTHMIAS?
Although the results of this study provide too limited a database for establishing definitive guidelines for practice, they underscore the need for critical care nurses to focus observations on patients' responses to iced fluid restriction. It is important to determine whether and to what extent limiting ingestion of iced fluids induces patient stress, a factor [...]
EFFECT OF SALT INTAKE ON RENAL EXCRETION OF WATER IN HUMANS
Two studies were performed to determine the quantitative relationship between salt intake and urinary volume (U(v)) in humans. In study 1, 104 untreated hypertensives were studied on the fifth day of a high- and a low-salt diet. The 24-hour U(v) was 2.2 L (urinary sodium [U(Na)] 277 mmol) on the high-salt diet and decreased to [...]

EFFECTS OF FLUID, ELECTROLYTE AND SUBSTRATE INGESTION ON ENDURANCE CAPACITY
The availability of carbohydrate (CHO) as a substrate for the exercising muscles is known to be a limiting factor in the performance of prolonged cycle exercise, and provision of exogenous CHO in the form of glucose can increase endurance capacity. The present study examined the effects of ingestion of fluids and of CHO in different [...]
