The single category of fitness facilities cannot meet the needs of the 60-74-year-olds, so the fuzzy cluster analysis method is used to construct the function set of fitness facilities which can be modularized and integrated. Through the needs research and weight calculation, 13 secondary functional modules are obtained, and the correlation matrix of each module is constructed from the perspectives of functional domain, structural domain, and user demand domain. The data derives the comprehensive incidence matrix Rc standard index, which is input into the Matlab software to generate a dynamic clustering tree. Four types of fitness facilities suitable for the elderly are obtained. The fitness facilities are analyzed from the structural point of view, and finally the best function set of fitness facilities suitable for the elderly is obtained. The functional set of fitness facilities for the elderly established by the fuzzy cluster analysis method can effectively solve the diversified needs of the elderly in the community for fitness facilities, and provide new ideas for the subsequent design of fitness facilities for the elderly.
