Effects of Ramadan upon fluid and food intake, fatigue, and physical, mental, andsocial activities: a comparison between the UK and Libya.

Two studies were performed duringÂ Ramadan, one in theÂ UKÂ (N=31) and the other inÂ LibyaÂ (N=33). The aims were to assess some changes to lifestyle that are produced by fasting as well asÂ effectsÂ due to culture. Subjects were studied on eight separate occasions: four control days (two before and two afterÂ Ramadan) and four days during the four weeks ofÂ Ramadan itself. [...]

Effect of sodium in a rehydration beverage when consumed as a fluid or meal.

To investigate the impact of fluid composition on rehydration effectiveness, 30 subjects (15 men and 15 women) were studied during 2 h of rehydration after a 2.5% body weight loss. In a randomized crossover design, subjects rehydrated with water (H2O), chicken broth (CB: 109.5 mmol/l Na, 25.3 mmol/l K), a carbohydrate-electrolyte drink (CE: 16.0 mmol/l [...]

Metabolic and thermodynamic responses to dehydration-induced reductions in muscle blood flow in exercising humans

1. The present study examined whetherÂ reductionsÂ inÂ muscleÂ bloodÂ flowÂ with exercise-induced dehydration would reduce substrate delivery and metabolite and heat removal to and from active skeletal muscles during prolonged exercise in the heat. A second aim was to examine the effects of dehydration on fuel utilisation across theÂ exercisingÂ leg and identify factors related to fatigue. 2. Seven cyclists performed two [...]

EFFECT OF SALT AND WATER BALANCE ON RECOVERY OF GASTROINTESTINAL FUNCTION AFTER ELECTIVE COLONIC RESECTION: A RANDOMISED CONTROLLED TRIAL

BackgroundnnLow concentrations of albumin in serum and long gastric emptying times have been returned to normal in dogs by salt and water restriction, or a high protein intake. We aimed to determine the effect of salt and water balance on recovery of gastrointestinal function after elective colonic resection in human beings.nMethodsnnWe randomly allocated ten patients [...]

AMPK AGONISTS AMELIORATE SODIUM AND FLUID TRANSPORT AND INFLAMMATION IN CYSTIC FIBROSIS AIRWAY EPITHELIAL CELLS

The metabolic sensor AMP-activated kinase (AMPK) inhibits both the cystic fibrosis (CF) transmembrane conductance regulator (CFTR) Cl(-) channel and epithelial Na(+) channel (ENaC), and may inhibit secretion of proinflammatory cytokines in epithelia. Here we have tested in primary polarized CF and non-CF human bronchial epithelial (HBE) cells the effects of AMPK activators, metformin and 5-aminoimidazole-4-carboxamide-1-beta-D-riboside [...]

American College of Sports Medicine position stand. Exercise and fluidreplacement.

This Position Stand provides guidance on fluid replacement to sustain appropriate hydration of individuals performing physical activity. The goal of prehydrating is to start the activity euhydrated and with normal plasma electrolyte levels. Prehydrating with beverages, in addition to normal meals and fluid intake, should be initiated when needed at least several hours before the [...]

Dietary reference intakes for water, sodium, potassium, chloride and sulphate.

This report is one in a series that presents a comprehensive set of reference values for nutrient intakes for healthy U.S. and Canadian individuals and populations. It is a product of the Food and Nutrition Board (FNB) of the Institute of Medicine, working in cooperation with Canadian scientists. The report establishes a set of reference [...]

A META-ANALYSIS OF OUTCOMES OF HYDRATION INTERVENTION ON PHONATION THRESHOLD PRESSURE

OBJECTIVES: Vocal fold hydration is purported to promote optimal biomechanical characteristics of vocal fold mucosa, increase efficiency of vocal fold oscillation, and enhance voice quality. The purpose of this work was to determine the magnitude and consistency of the effect of vocal fold hydration on vocal fold function across published clinical studies. METHODS: We completed [...]

INHALED MANNITOL IMPROVES THE HYDRATION AND SURFACE PROPERTIES OF SPUTUM IN PATIENTS WITH CYSTIC FIBROSIS

The airway mucus in patients with cystic fibrosis (CF) is dehydrated and adhesive and accumulates in the airways, resulting in chronic inflammation, infection, and progressive loss of lung function. Inhaled mannitol improves mucus clearance and, when administered over 2 weeks, it improves lung function in CF (Jaques et al. Chest. 2008;133(6):1388-1396). The changes in the [...]

Effect of beverage osmolality on intestinal fluid absorption during exercise.

To determine how osmolality of an orally ingested fluid-replacement beverage would alter intestinal fluid absorption from the duodenum and/or jejunum during 85 min of cycle exercise (63.3 +/- 0.9% peak O2 uptake) in a cool environment (22 degreesC), seven subjects (5 men, 2 women, peak O2 uptake = 54.5 +/- 3.8 ml . kg-1 .
