Three series of experimental tests were conducted on subjects under both elevated and depressed thermal conditions. Tripartite series consisted of whole-body immersion excepting the head, whole-body immersion excepting the head and response limb, and immersion of the discrete-response limb. Measures of physiological and behavioural responses were made at sequential .4 degrees C changes during whole-body immersions and approximately 5 degrees C changes of water temperature during the immersion of a limb only. Results suggested that velocity of nerve conduction decreased with thermal depression. Premotor, motor, simple, and choice reaction times varied differentially as a function of the hot and cold conditions. Implications of these differential effects on neuromuscular function are examined with respect to person-machine performance in artificially induced or naturally occurring extremes of ambient temperature.
在热环境升高和降低的条件下，对受试者进行了三组实验测试。三组实验分别包括除头部外的全身浸入、除头部和反应肢体外的全身浸入以及离散反应肢体的浸入。在全身浸入过程中，以连续0.4摄氏度的变化进行生理和行为反应测量；在仅肢体浸入过程中，水温变化约5摄氏度。结果表明，神经传导速度随热环境降低而下降。运动前、运动、简单和选择反应时间随热冷条件的变化而有所不同。针对在人为诱导或自然发生的极端环境温度下的人机性能，研究了这些不同影响对神经肌肉功能的意义。
