BLOOD VOLUME: ITS ADAPTATION TO ENDURANCE TRAINING.
Expansion of blood volume (hypervolemia) has been well documented in both cross-sectional and longitudinal studies as a consequence of endurance exercise training. Plasma volume expansion can account for nearly all of the exercise-induced hypervolemia up to 2-4 wk; after this time expansion may be distributed equally between plasma and red cell volumes. The exercise stimulus [...]
ALTITUDE ACCLIMATIZATION AND BLOOD VOLUME: EFFECTS OF EXOGENOUS ERYTHROCYTE VOLUME EXPANSION.
We studied sea-level residents during 13 days of altitude acclimatization to determine 1) altitude acclimatization effects on erythrocyte volume and plasma volume, 2) if exogenous erythrocyte volume expansion alters subsequent erythrocyte volume and plasma volume adaptations, 3) if an increased blood oxygen content alters erythropoietin responses during altitude acclimatization, and 4) mechanisms responsible for plasma [...]

BLOOD VOLUME: IMPORTANCE AND ADAPTATIONS TO EXERCISE TRAINING, ENVIRONMENTAL STRESSES, AND TRAUMA/SICKNESS.
This paper reviews the influence of several perturbations (physical exercise, heat stress, terrestrial altitude, microgravity, and trauma/sickness) on adaptations of blood volume (BV), erythrocyte volume (EV), and plasma volume (PV). Exercise training can induce BV expansion: PV expansion usually occurs immediately, but EV expansion takes weeks. EV and PV expansion contribute to aerobic power improvements [...]
EFFECTS OF HYDRATION ON FEBRILE TEMPERATURE PATTERNS IN RABBITS
Patients with fever have a predisposition to experience dehydration, which may alter their thermoregulatory responses to elevated body temperature. In view of the recent discovery of the antipyretic activity of arginine vasopressin (AVP), it is possible that dehydration has a beneficial role during fever. Dehydration may enhance endogenous antipyresis by stimulating AVP release, making aggressive [...]
HYPONATREMIA AND RHABDOMYOLYSIS: A POSSIBLE RELATIONSHIP
A 40-year-old schizophrenic presenting with an acute toxic psychosis was found to be severely hyponatremic with a serum osmolality of 217 mOsm/kg. The patient was combative and required physical restraints. Shortly after admission the patient's serum transaminase level was elevated, and the next day the CPK value was 175,000 IU. In addition, his serum and [...]

THE IMPORTANCE OF GOOD HYDRATION FOR DAY-TO-DAY HEALTH.
The role of hydration in the maintenance of health is increasingly recognized. Studies in healthy adults show that even mild dehydration impairs a number of important aspects of cognitive function such as concentration, alertness, and short-term memory. However, due to the lack of suitable tools for assessment of hydration status, the effects of hydration on [...]
