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 [...]
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 (1200Â mLÂ 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 [...]
Progressive Dehydration during Cycling Increases Skeletal Muscle Glycogenolysis and Perceived Exertion in Hydrated Males.
This study investigated the effects of progressive mild dehydration during cycling on whole body substrate oxidation and skeletal muscle metabolism in recreationally active men. Subjects (n=9) cycled for 120 min at ~65% VO2peak (22.7°C, 32% RH) with water to replace sweat losses (HYD) or without fluid (DEH). Blood samples were taken at rest and every [...]
