HYPERHYDRATION: THERMOREGULATORY EFFECTS DURING COMPENSABLE EXERCISE-HEAT STRESS
This study examined the effects of hyperhydration on thermoregulatory responses during compensable exercise-heat stress. The general approach was to determine whether 1-h preexercise hyperhydration [29. 1 ml/kg lean body mass; with or without glycerol (1.2 g/kg lean body mass)] would improve sweating responses and reduce core temperature during exercise. During these experiments, the evaporative heat [...]
EFFECTS OF DEHYDRATION ON GASTRIC EMPTYING AND GASTROINTESTINAL DISTRESS WHILE RUNNING
Gastrointestinal distress is commonly reported by athletes after ingestion of a beverage. We speculate that ingestion may be occurring after dehydration has taken place. The high prevalence of GI disorders in marathon runners who have lost greater than or equal to 4% body weight supports this theory. To test this theory, the effects of dehydration, [...]
PHYSIOLOGICAL CONSEQUENCES OF HYPOHYDRATION: EXERCISE PERFORMANCE AND THERMOREGULATION
During exercise in the heat, sweat output often exceeds water intake, which results in a body water deficit or hypohydration. This water deficit occurs from both the intracellular and extracellular fluid compartments, and causes a hypertonic-hypovolemia of the blood. Aerobic exercise tasks are likely to be adversely affected by hypohydration; and the warmer the environment [...]

ROLE OF TASTE PREFERENCE ON FLUID INTAKE DURING AND AFTER 90 MIN OF RUNNING AT 60% VO2MAX IN THE HEAT
PURPOSE: The purpose of this study was to determine the relationship between taste preference and total fluid intake during a 90-min run at 60% VO2max as well as during a 90-min period of seated recovery under hyperthermic conditions (30 degrees C, 50% RH), comparing the ad libitum intake of water and two carbohydrate-electrolyte drinks (one [...]
