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 [...]
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 [...]

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 [...]
