Hydration, sweat and thermoregulatory responses to professional football training in the heat.

This study examined the relationship between intensity of training and changes in hydration status, core temperature, sweat rate and composition and fluid balance in professional football players training in the heat. Thirteen professional football players completed three training sessions; "higher-intensity" (140 min; HI(140)), "lower-intensity" (120 min; LI(120)) and "game-simulation" (100 min; GS(100)). Movement demands were [...]

Body Mass Change and Ultraendurance Performance: A Decrease in Body Mass Is Associated With an Increased Running Speed in Male 100-km Ultramarathoners.

Body mass change and ultraendurance performance: a decrease in body mass is associated with an increased running speed in male 100-km ultramarathoners. J Strength Cond Res 26(6): 1505-1516, 2012-We investigated, in 50 recreational male ultrarunners, the changes in body mass, selected hematological and urine parameters, and fluid intake during a 100-km ultramarathon. The athletes lost [...]

The effect of a meal and water loading on heart rate variability in children with functional dyspepsia

BACKGROUND: Alteration in autonomic function has been implicated as a possible pathophysiologic mechanism in functional dyspepsia (FD) in adults.nnMETHODS: This was a two-part study. For the first part of the study, nine children with FD and 28 controls underwent heart rate variability (HRV) analysis for 30 min baseline and for 60 min following a test [...]

Symptoms of heat illness in surface mine workers.

OBJECTIVE: To assess the symptoms of heat illness experienced by surface mine workers. METHODS: Ninety-one surface mine workers across three mine sites in northern Australia completed a heat stress questionnaire evaluating their symptoms for heat illness. A cohort of 56 underground mine workers also participated for comparative purposes. Participants were allocated into asymptomatic, minor or [...]

Hydration effects on thermoregulation and performance in the heat.

During exercise, sweat output often exceeds water intake, producing a water deficit or hypohydration. The water deficit lowers both intracellular and extracellular fluid volumes, and causes a hypotonic-hypovolemia of the blood. Aerobic exercise tasks are likely to be adversely effected by hypohydration (even in the absence of heat strain), with the potential affect being greater [...]

Nurse-physician communication concerning artificial nutrition or hydration (ANH) in patients with dementia: a qualitative study.

Aims and objectives. To explore nurses' experiences with nurse-physician communication during artificial nutrition or hydration (ANH) decision-making in hospitalised patients with dementia. Background.â€‚ Artificial nutrition or hydration decision-making often occurs in patients with dementia. Effective communication between professionals is extremely challenging in this population, because these patients are unable to communicate their treatment wishes. Design.â€‚ [...]

Urine specific gravity in exercisers prior to physical training.

UrineÂ specificÂ gravityÂ (USG) is used as an index of hydration status. Many studies have used USG to estimate pre-exercise hydration in athletes. However, very little is known about the pre-exercise hydration status of recreationalÂ exercisers. The purpose of the present study was to measure the pre-exercise USG in a large sample of recreationalÂ exercisersÂ who attended 2 different fitness centers [...]

Promoting and maintaining healthy hydration in patients.

Fluid is essential for life and health. Nurses have an important role in helping patients maintain optimal levels of hydration, particularly in hospital or residential settings where access to fluid is less likely to be under the patient's control. This article describes the benefits of healthy hydration, outlines guidelines on fluid requirements for different patient [...]

Effect of glycerol-induced hyperhydration on thermoregulation and metabolismduring exercise in heat.

This study examined theÂ effectÂ of glycerol ingestion on fluid homeostasis,Â thermoregulation, andÂ metabolismÂ during rest and exercise. Six endurance-trained men ingested either 1 g glycerol in 20 ml H2O x kg(-1) body weight (bw) (GLY) or 20 ml H2O x kg(-1) bw (CON) in a randomized double-blind fashion, 120 min prior to undertaking 90 min of steady state cycleÂ exercise(SS) [...]

Effects of rehydration fluid temperature and composition on body weight retention upon voluntary drinking following exercise-induced dehydration.

The purpose of this study was to determine the effects of beverage temperature and composition on weight retention and fluid balance upon voluntary drinking following exercise induced-dehydration. Eight men who were not acclimated to heat participated in four randomly ordered testing sessions. In each session, the subjects ran on a treadmill in a chamber maintained [...]
