Water intake and post-exercise cognitive performance: an observational study of long-distance walkers and runners.

PURPOSE: The impact of diet on endurance performance and cognitive function has been extensively researched in controlled settings, but there are limited observational data in field situations. This study examines relationships between nutrient intake and cognitive function following endurance exercise amongst a group of 33 recreational runners and walkers. METHODS: All participants (mean age of [...]

Dysphagia, nutrition, and hydration in ischemic stroke patients at admission and discharge from acute care.

Dysphagia may predispose stroke patients toward undernutrition and hydration. These comorbidities increase patient risks for reduced functional outcome and short-term mortality. Despite this impact, available information on relationships among dysphagia, nutrition, and hydration status in acute stroke is limited and conflicted. This study evaluated nutrition and hydration status in ischemic stroke patients with versus without [...]

Physiologic basis for understanding quantitative dehydration assessment.

Dehydration (body water deficit) is a physiologic state that can have profound implications for human health and performance. Unfortunately, dehydration can be difficult to assess, and there is no single, universal gold standard for decision making. In this article, we review the physiologic basis for understanding quantitative dehydration assessment. We highlight how phenomenologic interpretations of [...]

The child’s body without fluid: mother’s knowledge and practices about hydration and rehydration in Salvador, Bahia, Brazil.

BACKGROUND: The aim of this article was to anthropologically analyse knowledge and practices about hydration and rehydration in a specific ethnographic context, where diverse therapies are combined to treat and take care of child diarrhoea as part of a wider social process that circumscribes transactions between self-care and biomedicine. METHODS: Ethnographic data from a qualitative [...]

What Do Athletes Drink During Competitive Sporting Activities?

Although expert groups have developed guidelines for fluid intake during sports, there is debate about their real-world application. We reviewed the literature on self-selected hydration strategies during sporting competitions to determine what is apparently practical and valued by athletes. We found few studies of drinking practices involving elite or highly competitive athletes, even in popular [...]

The Effect of Ice Slushy Ingestion and Mouthwash on Thermoregulation and Endurance Performance in the Heat.

PURPOSE: To establish whether sensory factors associated with cold beverage ingestion exert an ergogenic effect on endurance performance independent of thermoregulatory and/or cardiovascular factors. METHODS: Ten males performed three trials involving 90min steady state cycling (SS) (62% VO2max) in the heat (32.1±0.9°C, 40±2.4% relative humidity) followed by a 4kJ/kg body mass time trial (TT). During [...]

The Effects of High Intensity Intermittent Exercise Compared to Continuous Exercise on Voluntary Water Ingestion.

Water intake occurs following a period of high intensity intermittent exercise (HIIE) due to sensations of thirst yet this does not always appear to be caused by body water losses. Thus, the aim was to assess voluntary water intake following HIIE. Ten healthy males (22±2y, 75.6±6.9kg, VO2peak 57.3±11.4ml.kg-1.min-1) (mean±SD) completed two trials (7-14d apart). Subjects [...]

Do Heat Events Pose a Greater Health Risk for Individuals with Type 2 Diabetes?

Abstract Chronic medical conditions such as type 2 diabetes may alter the body's normal response to heat. Evidence suggests that the local heat loss response of skin blood flow (SkBF) is affected by diabetes-related impairments in both endothelium-dependent and non-endothelium-dependent mechanisms, resulting in lower elevations in SkBF in response to a heat or pharmacological stimulus. [...]

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

PURPOSE: This work combines and reanalyzes 5 yr of exercise-associated hyponatremia (EAH) research at 161-km ultramarathons in northern California with primary purposes to define the relationship between postrace blood sodium concentration ([Na]) and change in body weight; to examine the interactions among EAH incidence, ambient temperature, and hydration state; and to explore the effect of [...]
