Heat stress and acclimation.
Heat stress reduces the capability for sustained exercise. On the other hand, with repeated exposures to hot environments, exhaustion is delayed. This paper examines the hypothesis that high core temperature might be the ultimate cause of the fatigue and inability to continue to exercise in hot dry environmental conditions. It is suggested that a high core temperature is the ultimate cause of f...
متن کاملExtracellular Fluid Volume Changes in Carcinus Maenas during Acclimation to Low and High Environmental Salinities
Changes in extracellular fluid (ECF) volume of Carcinus maenas (L.) were studied in vivo during acclimation to low and high environmental salinities. Initial investigations showed that there was a rapid equilibration into this compartment of the ECF markers used ([H]inulin and pKJjhydroxymethyl inulin). Earlier reports of a relatively slow marker distribution, indicated from clearance curves, c...
متن کاملHeat acclimation improves exercise performance.
This study examined the impact of heat acclimation on improving exercise performance in cool and hot environments. Twelve trained cyclists performed tests of maximal aerobic power (VO2max), time-trial performance, and lactate threshold, in both cool [13°C, 30% relative humidity (RH)] and hot (38°C, 30% RH) environments before and after a 10-day heat acclimation (∼50% VO2max in 40°C) program. Th...
متن کاملGenomics and proteomics of heat acclimation.
Plasticity of the thermoregulatory system is a key factor for the induction of heat acclimation. Temperature-adaptive shifts in gene expression play an essential role in the processes involved. This review attempts to bridge the gap between the classical physiological heat acclimation profile and the molecular/cellular mechanisms underlying the evolution of the acclimated phenotype. Essential a...
متن کاملHeat acclimation and thirst in rats
The effects of heat acclimation on water intake and urine output responses to thermal dehydration and other thirst stimuli were studied in male Sprague-Dawley rats. Rats were heat acclimated by continuous exposure to a 34°C environment for at least 6 weeks. Thermal dehydration-induced thirst was brought about by exposing the heat-acclimated rats and control rats housed at 24°C to a 37.5°C envir...
