Few studies have evaluated the physiological burden of crawling, especially for children. The method of using wearable sensors to collect data (e.g., electrodermal activity, EDA; skin temperature, SKT) was used to evaluate the effects of different locomotive postures on children\u2019s velocity and physiological demands. Twenty-eight (28) children (13 boys and 15 girls), aged 4 to 6 years old, traveled up to 22.0 m in different postures: Upright walking (UW), stoop walking (SW), knee and hand crawling (KHC). The results showed that: (1) Gender and age had significant impacts on children\u2019s velocity (p &lt; 0.05): Boys were always faster than girls in any of the three postures and the older the child, the faster the velocity for KHC. (2) Physiological results demonstrated that KHC was more physically demanding than bipedal walking, represented by higher scores of the EDA and SKT indicators, similar to the findings of adults. (3) Gender and age had significant impacts on children\u2019s physiological demands (p &lt; 0.05). The physiological demands were greater for boys than girls. In addition, the higher the age, the less physiological demands he\/she needs. Overall, the findings suggest that children are unnecessarily required to choose crawling precisely as adults as the best posture to respond to emergency scenarios. In a severe fire, stoop walking is suggested, as there is more respired air and children could move quickly and avoid overworking physiological burdens. The results of this study are expected to be considered in the evaluation of current evacuation recommendations and for the safety guide of preparedness to improve the effectiveness of risk reduction for children.<\/jats:p>","DOI":"10.3390\/s22218094","type":"journal-article","created":{"date-parts":[[2022,10,24]],"date-time":"2022-10-24T10:09:23Z","timestamp":1666606163000},"page":"8094","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Associations between Evacuation Movements and Children\u2019s Physiological Demands Analyzed via Wearable-Based Sensors"],"prefix":"10.3390","volume":"22","author":[{"given":"Bo","family":"Zhang","sequence":"first","affiliation":[{"name":"Architecture College, Inner Mongolia University of Technology (IMUT), Hohhot 010051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyu","family":"Gao","sequence":"additional","affiliation":[{"name":"Architecture College, Inner Mongolia University of Technology (IMUT), Hohhot 010051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7720-0700","authenticated-orcid":false,"given":"Jiaxu","family":"Zhou","sequence":"additional","affiliation":[{"name":"UCL Institute for Environmental Design and Engineering, The Bartlett, University College London (UCL), London WC1H 0NN, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohu","family":"Jia","sequence":"additional","affiliation":[{"name":"Architecture College, Inner Mongolia University of Technology (IMUT), Hohhot 010051, China"},{"name":"Inner Mongolia Key Laboratory of Green Building, Architecture College, Inner Mongolia University of Technology (IMUT), Hohhot 010051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"163","DOI":"10.1007\/BF02601782","article-title":"Smoke movement in buildings","volume":"3","author":"Mcguire","year":"1967","journal-title":"Fire Technol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1125","DOI":"10.1016\/j.ssci.2007.06.011","article-title":"Decision analysis on fire safety design based on evaluating building fire risk to life","volume":"46","author":"Chu","year":"2008","journal-title":"Saf.
