Investigating the associations between hydration and exercise performance: methodology and limitations.

Loss of body water, if sufficiently severe, impairs most physiological functions, but the body water content fluctuates over the course of a normal day with no implications for physical or mental performance. The point at which an effect of dehydration becomes apparent has been the subject of much debate, in part, at least, because of [...]

A randomised controlled trial to investigate the effects of dehydration on tooth colour.

OBJECTIVES: To assess effects of dehydration on tooth colour. To investigate any change in tooth colour resulting from dehydration and the time required for any change to return to baseline. METHODS: 20 subjects with intact maxillary central incisors were recruited. In each case one incisor was randomly assigned as test tooth with the other acting [...]

The effect of prescribed fluid consumption on physiology and work behavior of wildfire fighters.

The purpose of this study was to examine 1) wildfire fighters' ability to consume the prescribed fluid volume (1200 mL h(-1)), 2) the effect of fluid intake on plasma sodium and hydration, and 3) the effect of fluid intake on firefighters' heart rate, core temperature and activity during emergency suppression shifts. METHODS: Thirty-four firefighters were divided into [...]

Hydration-dehydration, heat, humidity, and “cool, clear, water”.

Personal recollections of dehydration meltdowns during the Kona Ironman Triathlon, reflections on their cause, and the author's experiential recommendations regarding hydration, prevention of dehydration, and "beat the heat and humidity" measures. http://www.ncbi.nlm.nih.gov/pubmed/23147099n

Exercise-Associated Hyponatremia and Hydration Status in 161-km Ultramarathoners.

PURPOSE: This work combines and reanalyzes five years of exercise-associated hyponatremia (EAH) research at 161-km ultramarathons in northern California with primary purposes to define the relationship between post-race blood sodium concentration ([Na]) and change in body weight, examine the interactions among EAH incidence, ambient temperature and hydration state, and explore the effect of hydration status [...]

Controlling the hydration of the skin though the application of occluding barrier creams.

The skin is a barrier membrane that separates environments with profoundly different water contents. The barrier properties are assured by the outer layer of the skin, the stratum corneum (SC), which controls the transepidermal water loss. The SC acts as a responding membrane, since its hydration and permeability vary with the boundary condition, which is [...]

A rapid beverage intake questionnaire can detect changes in beverage intake.

Attention on beverage intake, specifically sugar-sweetened beverages (SSB), has increased in recent years. A brief valid, reliable and sensitive assessment tool for quantifying beverage consumption and determining its influence on weight status could help to advance research on this topic. The valid and reliable 15-item beverage questionnaire (BEVQ-15) estimates mean daily intake of water, SSB [...]

Nutrition and Fluid Optimization for Patients With Short Bowel Syndrome.

  Short bowel syndrome (SBS) is characterized by nutrient malabsorption and occurs following surgical resection, congenital defect, or disease of the bowel. The severity of SBS depends on the length and anatomy of the bowel resected and the health of the remaining tissue. During the 2 years following resection, the remnant bowel undergoes an adaptation [...]

Water consumption, not expectancies about water consumption, affects cognitive performance in adults.

Research has shown that water supplementation positively affects cognitive performance in children and adults. The present study considered whether this could be a result of expectancies that individuals have about the effects of water on cognition. Forty seven participants were recruited and told the study was examining the effects of repeated testing on cognitive performance. [...]

Food consumption and cardiovascular risk factors in European children: the IDEFICS study.

What is already known about this subject: Few studies addressing the relationship between food consumption and cardiovascular disease or metabolic risk have been conducted in children. Previous findings have indicated greater metabolic risk in children with high intakes of solid hydrogenated fat and white bread, and low consumption of fruits, vegetables and dairy products. What [...]
