Hydration status in college football players during consecutive days of twice-a-day preseason practices.
BACKGROUND: Football players lose 3.5 to 5 kg of body weight during preseason practices because of heavy sweating. This fluid may be difficult to replace when practices occur 2 times per day on consecutive days. HYPOTHESIS: Football players are hypohydrated during twice-a-day preseason training in a hot, humid environment. STUDY DESIGN: Descriptive laboratory study. METHODS: [...]
Aquaporin-related disorders of water homeostasis.
The discovery of four major water channels in the kidney, namely aquaporins (AQP) 1, 2, 3 and 4, has allowed a substantial increase in our understanding of renal water regulation in health and disease. This review discusses the renal aquaporin water channels in the urinary dilution and concentrating defects in cardiac failure, cirrhosis, syndrome of [...]

EFFECT OF MATERNAL HYDRATION ON OLIGOHYDRAMNIOS: A COMPARISON OF THREE VOLUME EXPANSION METHODS.
OBJECTIVE: To determine the effect of maternal hydration with intravenous (i.v.) isotonic fluid, i.v. hypotonic fluid, and oral water on amniotic fluid index (AFI) in women with oligohydramnios. METHODS: Patients with low AFI and gestational age over 35 weeks without maternal complications were randomized into four groups (2 L/2 h i.v. isotonic fluid, 2 L/2 [...]
Unifying hypothesis of sodium and water regulation in health and disease.
Sodium and water retention is characteristic of edematous disorders including cardiac failure, cirrhosis, nephrotic syndrome, and pregnancy. Nonosmotic vasopressin release has been implicated in the water retention of these edematous disorders. The nonosmotic release of vasopressin is consistently associated with activation of the sympathetic nervous and renin-angiotensin-aldosterone systems in both experimental animals and in edematous [...]
Hydration and vascular fluid shifts during exercise in the heat.
This study examined the effects of hypohydration on plasma volume and red cell volume during rest in a comfortable (20 degrees C, 40% relative humidity) and exercise in a hot-dry (49 degrees C, 20% relative humidity) environment. A group of six male and six female volunteers [matched for maximal O2 uptake (VO2 max)] completed two [...]
The effects of fluid restriction on hydration status and subjective feelings in man.
Hydration status and the effects of hypohydration have been the topic of much public and scientific debate in recent years. While many physiological responses to hypohydration have been studied extensively, the subjective responses to hypohydration have largely been ignored. The present investigation was designed to investigate the physiological responses and subjective feelings resulting from 13, [...]
