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 [...]

PSYCHOMOTOR DETERIORATION DURING EXPOSURE TO HEAT

The effect of different heat loads on vigilance and complex cognitive tasks involved in a mission of different intensities were examined. Nine healthy volunteers were randomly exposed for 2 h to three climatic conditions: comfort (21 degrees C ET), moderate heat load (30 degrees C ET) and severe heat load (35 degrees C ET). The [...]

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 [...]

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 [...]
