ObjectiveThe main aim of this research was to determine the relationships among executive function, fitness mobile applications (APPs), physical exercise activity and physical education consumption in community-dwelling older empty nesters. MethodsA cross-sectional design was applied to evaluate the relationships. A sample of 1104 community-dwelling older empty nesters completed the experiments. Physical education consumption scale, fitness APPs by smartphone application scale, physical exercise activity scale, and executive function scale were applied for the evaluation of the elderly alone in urban communities in southeast China. To explore mediating effects, structural equation modeling of AMOS 23.0, SPSS 25.0 and Process V3.5 software packages were applied for statistical processing. ResultPhysical education consumption positively predicted executive function. Meanwhile, it was also found that physical education consumption and executive function were continuously mediated by fitness APP application and physical exercise activity, with indirect effect value of 0.267, accounting for 76 %. ConclusionThis research revealed how physical education consumption affected executive function of older empty nesters. The obtained results had certain implications for older empty nesters to better balance their executive function and life quality. Community managers should provide older empty nesters with favorable physical education environments in terms of positive physical and psychological environments, to improve their use ratio of fitness APPs usage and physical exercise activity, ultimately enhancing their executive function and life satisfaction.
