摘要

轶事证据表明,一些英国军事潜水支援艇人员手脚冰冷,这可能会影响他们的表现,并与核心体温下降有关。本研究收集了参加寒冷天气训练的人员的热应激和认知表现的初步数据。在一系列气候条件下(气温+1.2°C至-10.5°C,风寒-4.5°C至19.3°C),对六名男子进行了四次船只过境监测。用无线电药丸和12个皮肤部位(ISO 9886加上手、手指、脚和脚趾)用iButton或热敏电阻测量核心体温。还记录了自我报告的热舒适性和热感觉。反应时间和选择性注意力在转运前后进行测量。记录参与者的身体特征和个人服装。没有参与者体温过低。大多数参与者的手、脚和手指温度降至15°C以下,这表明除了手套外,还有灵活性受损的风险。在试验过程中,手和手指的温度偶尔会降至10°C以下。收集到的有限数据表明,个人服装的选择可以为这些条件和温度提供足够的热保护,并强调了个体间的差异以及考虑日常环境条件显著变化的必要性。

A preliminary study of the thermal strain experienced by dive support boat personnel.

Anecdotal evidence indicated some British military dive support boat personnel suffer from uncomfortably cold hands and feet, which could impair their performance and be associated with reductions in core body temperature. This study collected preliminary data on thermal stress and cognitive performance of personnel taking part in a cold-weather training exercise. Six men were monitored during four boat transits in a range of climatic conditions (air temperature +1.2°C to -10.5°C, wind chill -4.5°C to 19.3°C). Core body temperature was measured with a radio pill and 12 skin sites (ISO 9886 plus hand, finger, foot and toe) with iButtons or thermistors. Self-reported thermal comfort and thermal sensation was also recorded. Reaction time and selective attention were measured pre- and post-transit. Participants' physical characteristics and personal clothing ensembles were recorded. No participant became hypothermic. Most participants' hand, foot and digit temperatures fell to below 15°C, indicating a risk of impaired dexterity, in addition to that arising from gloves. During the trial, hand and digit temperatures occasionally fell below 10°C. The limited data collected showed personal clothing choices could provide adequate thermal protection for these conditions and temperatures, and highlighted inter-individual variation and the need to allow for significant variation of day-to-day environmental conditions.

期刊介绍: The International Journal of Circumpolar Health is published by Taylor & Francis on behalf of the Circumpolar Health Research Network [CircHNet]. The journal follows the tradition initiated by its predecessor, Arctic Medical Research. The journal specializes in circumpolar health. It provides a forum for many disciplines, including the biomedical sciences, social sciences, and humanities as they relate to human health in high latitude environments. The journal has a particular interest in the health of indigenous peoples. It is a vehicle for dissemination and exchange of knowledge among researchers, policy makers, practitioners, and those they serve. International Journal of Circumpolar Health welcomes Original Research Articles, Review Articles, Short Communications, Book Reviews, Dissertation Summaries, History and Biography, Clinical Case Reports, Public Health Practice, Conference and Workshop Reports, and Letters to the Editor.
