摘 要:为了研究中国南北方男性大学生在可接受冷环境区生理适应的自主性调节反应和主观感受的差异,选取南北方受试者各16名,遴选生理指标包括皮肤温度、心率(HR)、心率变异性(HRV)、呼吸率、血容量(BVP)、肌电(EMG),填写主观问卷。结果表明:南方受试者主观感受好于北方受试者;平均皮肤温度、EMG均值稍高于北方受试者;北方受试者心率值、LF/HF均值高于南方受试者;南北受试者从中性环境进入可接受冷环境区,南方受试者的主观感受指标差分均值和生理反应指标差分均值出现显著性差异的实验时间段明显少于或晚于北方受试者。结论:北方受试者对偏冷的环境更敏感,冷耐受力比南方受试者弱;冷习服弱,产生了较强的生理调节现象;南方受试者基础代谢和非战栗产热(代谢产热)稍高于北方受试者,产生较小的生理调节,有较好的冷环境忍耐力和较强的冷习服能力。

Abstract:This paper focuses on the physiological adaption and subjective sensation in cold acceptable environment zone between male college students of southern and northern of China. 16 subjects of southern China and 16 subjects of northern China were selected, to test their physiological parameters including skin temperature, heart rate (HR), heart rate variability (HRV), blood volume pulse (BVP) and electromyogram (EMG), and to ask the subjects to fill in questionnaires. The experimental results revealed that: In terms of all subjective questions, southern subjects give a better response than northern subjects ; and have a higher average skin termperature and EMG value and a lower HR、LF/HF values than northern subjects; From neutral environment to cold acceptable environment zone, the experimental period ...
