Heat stress: physiology of acclimation and adaptation

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...

Physiology, idiosyncrasy and heat stress limits.

Metabolic and hormonal acclimation to heat stress in domesticated ruminants.

Environmentally induced periods of heat stress decrease productivity with devastating economic consequences to global animal agriculture. Heat stress can be defined as a physiological condition when the core body temperature of a given species exceeds its range specified for normal activity, which results from a total heat load (internal production and environment) exceeding the capacity for he...

Psychological Adaptation To Heat Stress

By Ralph A. Vernacchia, Ph.D., and Sylvia Veit-Hartley, B.A. Center for Performance Enhancement, Western Washington University This excellent work by Vernacchia and Veit-Hartley was presented at the Coaching Education Level III in December, 1998. It not only shows the quality of the authors’ research and writing, but also the what one might fi nd at a Level III seminar. Both authors are to be c...

Adaptation and acclimation of aerobic exercise physiology in Lake Whitefish ecotypes (Coregonus clupeaformis).

The physiological mechanisms underlying local adaptation in natural populations of animals, and whether the same mechanisms contribute to adaptation and acclimation, are largely unknown. Therefore, we tested for evolutionary divergence in aerobic exercise physiology in laboratory bred, size-matched crosses of ancestral, benthic, normal Lake Whitefish (Coregonus clupeaformis) and derived, limnet...
