目的 利用扎根理论研究方法对适老户外健身设施舒适度优化设计策略进行探究。方法 首先通过深度访谈与整理数据，运用Nvivo12软件进行质性研究分析，明确了适老户外健身设施舒适度影响因子;其次采用问卷调查的方式搜集数据，运用SPSS26软件对其进行信效度分析和因子分析，证明了适老户外健身设施舒适度影响因子理论模型的合理性;最后提出适老户外健身设施舒适度优化设计策略，并应用于适老户外健身设施的设计实践中。结果 行为舒适度、心理舒适度和知觉舒适度是适老户外健身设施舒适度影响因子理论模型的核心类属，根据核心类属提出适老户外健身设施的优化设计策略及方案。结论 研究结果表明，基于扎根理论的研究方法对提高适老户外健身设施的舒适度具有积极的实践价值。

The work aims to study the optimization design strategy for the comfort of the elderly-oriented outdoor fitness facilities with the grounded theory. Through in-depth interviews and data collation, Nvivo 12 software was used to carry out qualitative research and analysis to clarify the comfort influencing factors of elderly-oriented outdoor fitness facilities. Then, data were collected by questionnaire survey and SPSS 26 software was used to analyze the reliability and validity to prove the rationality of the theoretical model of comfort influencing factors of the elderly-oriented outdoor fitness facilities. Finally, the comfort optimization design strategy of the elderly-oriented outdoor fitness facilities was proposed and applied to the design practice of the elderly-oriented outdoor fitness facilities. Behavioral comfort, psychological comfort and perceived comfort were the core categories of the theoretical model of comfort influencing factors of the elderly-oriented outdoor fitness facilities. The research results show that the research method based on the grounded theory has positive practical value in improving the comfort of elderly-oriented outdoor fitness facilities.
