Effect of Preexercise Soup Ingestion on Water Intake and Fluid Balance During Exercise in the Heat.

PURPOSE: To determine whether chicken noodle soup before exercise increases ad libitum water intake, fluid balance, and physical and cognitive performance compared with water. METHODS: Nine trained men (age: 25±3y; VO2peak: 54.2±5.1ml·kg-1·min-1; mean±SD) performed cycle exercise in the heat (Wet Bulb Globe Temperature=25.9±0.4ºC) for 90min at 50% VO2peak, 45min after ingesting 355ml of either commercially-available [...]

Hydration status and fluid and sodium balance in elite Canadian junior women’s soccer players in a cool environment.

Dehydration can impair mental and on-field performance in soccer athletes; however, there is little data available from the female adolescent player. There is a lack of research investigating fluid and electrolyte losses in cool temperatures. Therefore, the purpose of this study was to investigate the pretraining hydration status, fluid balance, and sweat sodium loss in [...]

Relationship between thirst perception and plasma arginine vasopressin concentration in man.

We examined the possibility that measurements of thirst perception in man using the visual Analogue Scale (VAS) can be used to estimate plasma arginine vasopressin concentration in man. In thirty normal subjects (male=15 and female=15), thirst perception (TP, cm) was rated and 5.0ml blood samples were collected for the measurement of plasma arginine vasopressin (PAVP) [...]

Water-deficit equation: systematic analysis and improvement.

BACKGROUND: The water-deficit equation {WD(1) = 0.6 — B(m) — [1 - (140 · Na(+))]; B(m) denotes body mass} is used in medicine and nutrition to estimate the volume (L) of water required to correct dehydration during the initial stages of fluid-replacement therapy. Several equation assumptions may limit its accuracy, but none have been systematically [...]

The effects of Ramadan intermittent fasting on athletic performance: Recommendations for the maintenance of physical fitness.

Abstract. The behavioural modifications that accompany Ramadan intermittent fasting (RIF) are usually associated with some alterations in the metabolic, physiological, and psychological responses of athletes that may affect sport performance. Muslim athletes who are required to train and/or compete during the month-long, diurnal fast must adopt coping strategies that allow them to maintain physical fitness [...]

Significant and serious dehydration does not affect skeletal muscle cramp threshold frequency.

OBJECTIVE: Many clinicians believe that exercise-associated muscle cramps (EAMC) occur because of dehydration. Experimental research supporting this theory is lacking. Mild hypohydration (3% body mass loss) does not alter threshold frequency (TF), a measure of cramp susceptibility, when fatigue and exercise intensity are controlled. No experimental research has examined TF following significant (3-5% body mass [...]

Drinking water is associated with weight loss in overweight dieting women independent of diet and activity.

BACKGROUND: Data from short-term experiments suggest that drinking water may promote weight loss by lowering total energy intake and/or altering metabolism. The long-term effects of drinking water on change in body weight and composition are unknown, however. OBJECTIVE: This study tested for associations between absolute and relative increases in drinking water and weight loss over 12 months. METHODS AND PROCEDURES: Secondary analyses were conducted on data from the Stanford A TO Z weight loss intervention [...]

Replacing sweetened caloric beverages with drinking water is associated with lowerenergy intake.

OBJECTIVE: Reduced intake of sweetened caloric beverages (SCBs) is recommended to lower total energy intake. ReplacingSCBs with non-caloric diet beverages does not automatically lower energy intake, however. Compensatory increases in other food or beverages reportedly negate benefits of diet beverages. The purpose of this study was to evaluate drinking water as an alternative to SCBs. RESEARCH METHODS AND PROCEDURES: Secondary analysis of data from the Stanford A TO Z intervention evaluated change in beverage pattern [...]
