Eight nude resting men were exposed to consecutive heating-cooling cycles of air and wall temperatures varying from 28 to 45 degrees C in a sawtooth pattern using one of the following slopes: +/- 3.40, +/- 2.27, +/- 1.70, +/- 1.42, or +/- 1.13 degrees C . min-1. Ambient vapor pressure and air velocity were kept constant at 20.0 mbar and 0.9 m . s-1, respectively. Continuous measurements were made of rectal, esophageal, and mean skin temperatures. Local upper limb sweating response was measured from an arm chamber under a local thermal clamp. The results point out the insufficiency of an explantation based on a simple additive function of core and skin temperatures for describing the sweating regulation. During transient thermal loads, a multiplicative interaction of mean skin and core temperatures must also be taken into account for describing the central drive for local sweating response. The interindividual differences observed in the sweating regulation mechanism seem to be linked to a nonlinearity in the response of the thermoregulatory system.
八名裸体静息男性暴露于空气和壁温以锯齿模式在28至45摄氏度之间连续进行加热-冷却循环的环境中,加热-冷却循环采用以下斜率之一:±3.40、±2.27、±1.70、±1.42或±1.13摄氏度·分钟⁻¹。环境蒸汽压和空气流速分别保持在20.0毫巴和0.9米·秒⁻¹恒定。连续测量直肠、食管和平均皮肤温度。通过局部热钳从手臂腔室测量局部上肢出汗反应。结果指出,基于核心温度和皮肤温度的简单相加函数来描述出汗调节的外植体方法是不够的。在瞬态热负荷期间,为了描述局部出汗反应的中枢驱动,还必须考虑平均皮肤温度和核心温度的乘法相互作用。在出汗调节机制中观察到的个体差异似乎与体温调节系统反应的非线性有关。
