Methods for assessing the effects of dehydration on cognitive function.

Studying the effects of dehydration on cognitive function presents a variety of unique and difficult challenges to investigators. These challenges, which are addressed in this article, can be divided into three general categories: 1) choosing an appropriate method of generating a consistent level of dehydration; 2) determining and effectively employing appropriate and sensitive measures of [...]

Hydration for recreational sport and physical activity.

This review presents recommendations for fluid needs and hydration assessment for recreational activity. Fluid needs are based on sweat losses, dependent on intensity and duration of the activity, and will vary among individuals. Prolonged aerobic activity is adversely influenced by dehydration, and heat exposure will magnify this effect. Fluid needs predicted for running 5-42 km at [...]

Thirst and hydration status in everyday life.

Water is an essential nutrient for all persons; thus, maintaining a chronic state of optimal hydration is recognized to provide health benefits. Fluid balance is maintained via thirst, a feedback-controlled variable, regulated acutely by central and peripheral mechanisms. However, voluntary drinking is also a behavior influenced by numerous social and psychological cues. Therefore, whether "thirst-guided" [...]

Parenteral Hydration in Patients With Advanced Cancer: A Multicenter, Double-Blind, Placebo-Controlled Randomized Trial.

PURPOSE: The vast majority of patients with cancer at the end of life receive parenteral hydration in hospitals and no hydration in hospice, with limited evidence supporting either practice. In this randomized controlled trial, we determined the effect of hydration on symptoms associated with dehydration, quality of life, and survival in patients with advanced cancer. [...]

The effect of acute fluid consumption and hydration status on percent body fat and minimum wrestling weight.

ABSTRACT: The weight certification program for wrestling requires a urine specific gravity (Usg) < 1.020. However, the effect of acute rehydration on percent body fat (%BF) and minimum wrestling weight (MWW) is largely unknown. We examined the effect of acute fluid consumption on %BF and MWW. Twenty-five male subjects (18-22 y) were tested in a [...]

Ad Libitum Fluid Intake does not Prevent Dehydration in Sub-optimally Hydrated Young Soccer Players during a Training Session of a Summer Camp.

There is a lack of studies concerning hydration status of young athletes exercising in the heat. PURPOSE: To assess pre-exercise hydration status in young soccer players during a summer sports camp and to evaluate body water balance after soccer training sessions. METHODS: Initial hydration status was assessed in 107 young male soccer players (age: 11-16 [...]

Hydration, morbidity, and mortality in vulnerable populations.

Both acute and chronic fluid deficits have been shown to be associated with a number of adverse health outcomes. At the extreme, deprivation of water for more than a few days inevitably leads to death, but even modest fluid deficits may precipitate adverse events, especially in young children, in the frail elderly and in those [...]

Dehydration and endurance performance in competitive athletes.

The field of research examining the link between dehydration and endurance performance is at the dawn of a new era. This article reviews the latest findings describing the relationship between exercise-induced dehydration and endurance performance and provides the knowledge necessary for competitive, endurance-trained athletes to develop a winning hydration strategy. Acute, pre-exercise body weight loss [...]
