项目摘要

We obtained the following findings in this research by the some creative techniques developed in the physio-anthropological field.1. Fatty subjects had smaller changes in skin temperature (TィイD2skィエD2) at the trunk and larger changes in peripheral TィイD2skィエD2 than lean subjects under both hot (37 ゜C) to cool (17 ゜C) and cool to hot conditions.2. TィイD2skィエD2 of subjects from the warm district (Kyushu) was higher than that from the cold district (Hokkaido and Tohoku) in a hot environment (40゜C). However, changes in TィイD2skィエD2 during the experiment showed higher value in the subjects from the cold district.3. There were significant correlations between increases in thermal sensation and in α2 band of electroencephalogram (EEG) during thermal stimuli applied to palm, and between increases in thermal comfort and in β1 band of EEG. Both increase in thermal sensation and decrease in thermal comfort showed significant correlations with increase in brain blood flow.4. Increase in rectal temperature of children were smaller than that of young adults during immersion of their legs in a hot water bath (42゜C) in a hot environment (30゜C). It was suggested that children regulate their body temperature mainly through a dry heat loss in a hot environment.5. Thermal responses to a hot (35゜C) and a cold (5゜C) environment were different between Japanese and Korean females wearing T-shirt and short pants, however, the way of responses to each thermal stress was affected by whether wearing Kimono or Hanbok in each Japanese and Korean.6. The ratio of body surface area to body weight was estimated from the physique or body type of several population groups, and the regression equation between the ratio and the mean air temperature of their resident places was calculated. Japanese males and females are found to be completely contained in this relation.

本研究运用生理人类学领域的一些创新技术，获得了以下发现。在热（37 ° C）到冷（17 ° C）和冷到热条件下，肥胖受试者躯干皮肤温度（T D2sk D2）的变化较小，外周T D2sk D2的变化较大。在炎热的环境（40 ℃）下，温暖地区（九州）的受试者的T_（max）D_2高于寒冷地区（北海道和东北）。然而，在实验过程中，来自寒冷地区的受试者的T_（10）D_（20）K_（20）D_（20）的变化值较高.手掌热刺激时，热感觉的增加与脑电图（EEG）α2频段的增加有显著的相关性，热舒适性的增加与EEG β1频段的增加有显著的相关性。热感觉的增加和热舒适的降低与脑血流量的增加有显著的相关性.在热环境（30 ℃）下将腿浸入热水浴（42 ℃）中时，儿童直肠温度的升高幅度小于年轻成人。提示儿童在高温环境下主要通过干热散失来调节体温.穿着T恤和短裤的日本和韩国女性对热（35 ℃）和冷（5 ℃）环境的热反应不同，但穿着和服或韩服的日本和韩国女性对每种热应激的反应方式都受到影响.从几个人群的体质或体型估计体表面积与体重的比值，并计算出该比值与其居住地平均气温的回归方程。日本男性和女性被发现完全包含在这种关系中。
