Abstract: 【Purpose/significance】The popularity of wearable devices makes the quantification and management of personal health re⁃ ceive more and more attention and attention. Existing studies have confirmed that the ＂sports leaderboard＂ in social apps promotes the improvement of users' exercise data, but to what extent the exercise behavior in the form of ranking competition can promote users' subjective well-being and whether there are other influence paths remain to be explored.【Method/process】Based on the intensive lon⁃ gitude exercise data of 157 Xiaomi Mi Band users for 105 days, and combined with personality traits, this study analyzes the impact of exercise behavior on subjective well-being from the two paths of self and others.【Result/conclusion】The results show that: (1) The in⁃ fluence of self-path and others' path coexist, but the influence of self-determination is higher. (2) The user's exercise behavior can im⁃ prove their subjective well-being. (3) Users with high scores of extraversion personality are more likely to be motivated by others, and thus obtain higher subjective well-being.【Innovation/limitation】This paper distinguishes the two influence paths of self and others on subjective well-being, analyzes the moderating effect of personality traits, and verifies the positive promotion effect of gamification ranking setting on exercise behavior. Interaction provides cross-hierarchy analysis tools.
