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 [...]

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 [...]
