户外体育活动可以促进公众健康,并且在不同的城市环境中受到建筑环境的影响。了解户外体育活动与建筑环境之间的联系对于促进高质量的生活很重要。现有的研究通常使用基于访谈的小样本集中在一种类型的户外活动上,并且通常缺乏对活动强度和频率的系统理解。在这项研究中,我们打算使用从个人可穿戴设备和其他开放数据源中提取的数据进行综合分析,更深入地了解建筑环境如何影响身体活动。利用长沙市的数据,采用对数变换的多元线性回归进行分析,中国。我们发现,长沙建筑环境对户外体育活动的影响并不总是与其他城市的类似研究结果一致。推广户外体育活动的最有效措施是提供良好的主干道和二级道路网,社区公园,其他人在长沙。结果从促进公共卫生的角度揭示了未来的城市规划实践。
Outdoor physical activities can promote public health and they are largely influenced by the built environment in different urban settings. Understanding the association between outdoor physical activities and the built environment is important for promoting a high quality of life. Existing studies typically focus on one type of outdoor activity using interview-based small samples and are often lack of systematic understanding of the activities\' intensity and frequency. In this study, we intend to gain deeper insight into how the built environment influences physical activities using the data extracted from individual\'s wearables and other open data sources for integrated analysis. Multi-linear regression with logarithm transformation is applied to perform the analysis using the data from Changsha, China. We found that built environment impacts on outdoor physical activities in Changsha are not always consistent with similar studies\' results in other cities. The most effective measures to promote outdoor physical activities are the provision of good arterial and secondary road networks, community parks, among others in Changsha. The results shed light on future urban planning practices in terms of promoting public health.
