HYPONATREMIA IN DISTANCE RUNNERS: FLUID AND SODIUM BALANCE DURING EXERCISE
Since its first description in 1985, two opposing theories have evolved to explain the etiology of symptomatic hyponatremia of exercise. The first holds that the condition occurs only in athletes who lose both water and [...]
EFFECTS OF ACUTE PLASMA VOLUME EXPANSION ON ALTERING EXERCISE-HEAT PERFORMANCE
To determine the effect an acute plasma volume expansion has on body temperature responses and exercise performance in the heat, seven unacclimatized male volunteers attempted to complete two 90-min walks (45% of VO2 max) in [...]
HYPOHYDRATION AND THERMOREGULATION IN COLD AIR
This study examined the effects of hypohydration on thermoregulation during cold exposure. In addition, the independent influences of hypohydration-associated hypertonicity and hypovolemia were investigated. Nine male volunteers were monitored for 30 min at 25 degrees [...]
REVIEW: EXERCISE, HEAT, HYDRATION AND THE BRAIN
The performance of both physical and mental tasks can be adversely affected by heat and by dehydration. There are well-recognized effects of heat and hydration status on the cardiovascular and thermoregulatory systems that can account [...]
