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 [...]

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 [...]

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 [...]

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. [...]

Cognitive performance and hydration

No matter how mild, dehydration is not a desirable condition because there is an imbalance in the homeostatic function of the internal environment. This can adversely affect cognitive performance, not only in groups more vulnerable to dehydration, such as children and the elderly, but also in young adults. However, few studies have examined the impact [...]

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 [...]

A subjective evaluation of a drinking system for saturation divers.

Studies have shown that divers may lose large volumes of body fluids in hot water suit (HWS) dives lasting for four hours or longer, and that this dehydration is mainly caused by sweating. Body fluid balance may be impaired and the diver's alertness and power of judgement could be influenced by such imbalance. The main [...]

Medical sports injuries in the youth athlete: emergency management.

As the number of youth sports participants continues to rise over the past decade, so too have sports related injuries and emergency department visits. With low levels of oversight and regulation observed in youth sports, the responsibility for safety education of coaches, parents, law makers, organizations and institutions falls largely on the sports medicine practitioner. [...]

Acute effect of oral water intake during exercise on post-exercise hypotension.

Background/objectives: Post-exercise hypotension (PEH) is a sustained reduction in mean arterial blood pressure (MAP) after prolonged exercise. As water drinking is known to elicit a large acute pressor response, we aimed to explore the effect of drinking water during exercise on PEH. Subjects/methods: Ten normotensive male volunteers performed the control protocol: 30 min supine rest, 60 min [...]
