The independent roles of temperature and thermal perception in the control of human thermoregulatory behavior

摘要: The present study independently evaluated temperature and thermal perception as controllers of thermoregulatory behavior in humans. This was accomplished using a self-paced exercise heat stress model which twelve physically active male subjects exercised at constant subjective rating perceived exertion (16, ‘hard – very hard’) while their face thermally non-thermally cooled, heated, or left alone (control trial). Thermal cooling heating were achieved via forced convection, non-thermal the topical application menthol capsaicin solutions. Evidence for defined terms self-selected intensity, thus work output. results indicate that, absence changes temperature, warming elicited sensory discomfort sensations similar to those observed during warming. Furthermore, effort maintained throughout all trials, initial final intensities also similar. resulted highest output, lowest. Non-thermal control trials Heart rate, mean skin core (rectal) temperatures, whole body local (neck) sweat rates between trials. These data that are not requirement initiation Rather, sensation capable behavioral controllers.
