Physiological Changes During Five Days Of Heat Acclimation

Equine sweating responses to submaximal exercise during 21 days of heat acclimation.

This study examined sweating responses in six exercise-trained horses during 21 consecutive days (4 h/day) of exposure to, and daily exercise in, hot humid conditions (32-34 degrees C, 80-85% relative humidity). On days 0, 3, 7, 14, and 21, horses completed a standardized exercise test on a treadmill (6 degrees incline) at a speed eliciting 50% of maximal O(2) uptake until a pulmonary artery te...

The Impact of Hydration Status during Heat Acclimation on Physiological Strain and Exercise Performance

Acclimation Changes of Flavonoids in Needles of Conifers during Heat and Drought Stress 2015

The long-term harsh climate conditions in 2015 distorted already from June up to November in all study trees of Tsuga and Taxus the intracellular organization of the needles. Intimately involved in these repressive processes were the flavanols, a small subgroup of the flavonoids. They were not only deposited in vacuoles of conifer needles but also in the nuclei and chromosomes. Among the many f...

Effect of facial cooling during heat acclimation process on adaptive changes in sweating activity.

On assumptions that tympanic temperature (Tty) reflects brain temperature and that the latter can be lowered by cooling of the face, effect of facial cooling during acclimation process on adaptive changes in sweating activity was examined, in comparison with the results of our previous studies on heat acclimation with controlled hyperthermia. Face fanning, by which Tty was clamped at approximat...

The Effect of Ten Days of Heat Acclimation on Exercise Capacity during Acute Altitude Exposure (4350 m)

Acclimation to one environmental stressor may enhance adaptations to various other stressors in humans; this phenomenon has been described as cross-tolerance. Approaches to induce altitude acclimation in a relatively short time frame are needed, thus the purpose of our study was to examine the effect of heat acclimation on exercise capacity during acute altitude exposure (4350 m). Eight trained...
