Effects of hydration on cognitive function of pilots.

The objective of this study was to examine the effect of fluid intake and possible dehydration on cognitive flight performance of pilots. A repeated-measures, counterbalanced, mixed study design was used to examine differences in working memory, spatial orientation, and cognitive flight performance of 40 randomly selected healthy pilots after having high and low fluid intakes. [...]

Sports nutrition needs: before, during, and after exercise.

This article discusses how athletes should properly fuel their bodies before, during, and after exercise to maximize athletic performance. Emphasis is placed on hydration status and glycogen stores being maintained above deficits that negatively affect sport performance. Timing of nutrient intake is as important as composition. http://www.ncbi.nlm.nih.gov/pubmed/23668654

Total body water and its compartments are not affected by ingesting a moderate dose of caffeine in healthy young adult males.

Acute and chronic caffeine intakes have no impact on hydration status (R.J. Maughan and J. Griffin, J. Hum. Nutr. Diet. 16(6): 411-420, 2003), although no research has been conducted to analyze the effects using dilution techniques on total-body water (TBW) and its compartments. Therefore, the aim of this study was to investigate the effects of [...]

Case Study: Nutrition and Hydration Status During 4254km of Running Over 78 Consecutive Days

The aims of this study were to assess the dietary intake and monitor self-reported recovery quality and clinical symptomology of a male ultra-endurance runner who completed a multi-day ultra-endurance running challenge covering 4254km from North Scotland to the Moroccan Sahara desert over 78 consecutive days. Food and fluid intakes were recorded and analysed through dietary [...]

The Influence of Rehydration Mode Following Exercise Dehydration on Cardiovascular Function

Our purpose was to compare common modes of rehydration (REHY) on cardiovascular and fluid regulation recovery following exercise dehydration (EXDE). Twelve non-heat-acclimatized trained subjects (23±4y, 81.3±3.7kg, 180±6cm, 56.9±4.4mLminkg VO2max, 7.8±3.0 % body fat) completed 20-h fluid restriction and 2-h EXDE to -4% body mass, then were rehydrated to -2% body mass in a randomized, cross-over [...]

Thickening agents used for dysphagia management: effect on bioavailability of water, medication and feelings of satiety

Dysphagia is the medical term for difficulty swallowing. Thickened liquids are often used in the management of dysphagia to improve bolus control and to help prevent aspiration. A range of starches and gums has historically been used to thicken liquids. Although thickened liquids improve swallow safety, they appear to have a great potential for unintended [...]

Dehydration and acute weight gain in mixed martial arts fighters before competition

The purpose of this study was to characterize the magnitude of acute weight gain (AWG) and dehydration in mixed martial arts (MMA) fighters before competition. Urinary measures of hydration status and body mass were determined approximately 24 hours before and then again approximately 2 hours before competition in 40 MMA fighters (mean ± SE, age: [...]

Hydration biomarkers in free-living adults with different levels of habitual fluid consumption

Little is known about the impact of habitual fluid intake on physiology. Specifically, biomarkers of hydration status and body water regulation have not been adequately explored in adults who consume different fluid volumes in everyday conditions, without prolonged exercise or environmental exposure. The purpose of the present study was to compare adults with habitually different [...]

Thermal stress in north Western Australian iron ore mining staff.

INTRODUCTION: Demand for Australian mined iron ore has increased employment within this sector, thus exposing increased numbers of workers to the harsh Australian climate. This study examined the influence of hot (>30°C wet bulb globe temperature) environmental temperatures, consistent with working in North Western Australia, on iron ore mining staff. METHODS: Core temperature, hydration status, [...]

Hydration status of underground miners in a temperate Australian region

BACKGROUND: Dehydration is a health risk for miners in tropical regions of Australia. However, it is not known whether dehydration poses a health risk to miners working in temperate regions of Australia. METHODS: A cross-sectional study of 88 miners from two underground mines was undertaken in south-eastern New South Wales, Australia. Participants had their height, [...]
