日常生活行動負荷に関する実験 --皮膚温のちがいによる冬期洗足時の生体反応--

Abstract

The purpose of this study is to investigate and measure the physiologic changes involved in receiving a hot foot bath in the supine position in winter. Eleven, twenty-one years old female subjects, who were completely passive during the foot bathing, involved in this study. Six members of the group with high skin temperature (group H) were matched with six from the low skin temperature group (group L). One person was matched twice. The main resulte are as follows: 1) The temperature difference, as a ratio between group H, and group L, was 1:2. 2) For group L, the maximum skin temperature reached after five minutes immersion was 35.1℃. But longer immersion would probably produce higher skin temperature. 3) After twenty-three minutes, the skin temperature of group H reached a point lower than their initial skin temperature. After twenty-three minutes, group L however, had a skin temperature eight degrees higher than initially. 4) Two minutes after the experiment began, at the time of immersion, the expiration volume of group L feel below that of group H, but this is not a significant phenomenon. 5) In order to maintain homeostasis, the metabolic rate increased for group H as soon as the feet were removed from the footbath. But, for group L. the metabolic rate remained low.
