WATER AND CARBOHYDRATE INGESTION DURING PROLONGED EXERCISE INCREASE MAXIMAL NEUROMUSCULAR POWER.
This study investigated the individual and combined effects of water and carbohydrate ingestion during prolonged cycling on maximal neuromuscular power (P(max)), thermoregulation, cardiovascular function, and metabolism. Eight endurance-trained cyclists exercised for 122 min at 62% maximal oxygen uptake in a 35 degrees C environment (50% relative humidity, 2 m/s fan speed). P(max) was measured in [...]
THERMOREGULATION IN HYPERHYDRATED MEN DURING PHYSICAL EXERCISE
The influence of hyperhydration on thermoregulatory function was tested in 8 male volunteers. The subjects performed cycle exercise in the upright position at 52% Vo2max for 45 min in a thermoneutral (Ta = 23 degrees C) environment. The day after the control exercise the subjects were hyperhydrated with tap water (35 ml X kg-1 of [...]

FLUID AND ELECTROLYTE BALANCE: EFFECTS ON THERMOREGULATION AND EXERCISE 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 [...]

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 [...]
