Construction and Practical Application of a “Publicity–Participation–Guarantee–Feedback” Closed-Loop Promotion Model for Mass Trampoline in Chinese Universities

Mass trampoline refers to low-impact, music-synchronized group rebounding performed on small-diameter fitness trampolines. Although physiologically accessible and affectively rewarding for young adults, it remains largely absent from Chinese university curricula and campus sport systems, where four mutually reinforcing barriers—risk misperception, limited institutional recognition, thin resource provision, and episodic, unevaluated programming—sustain a self-reinforcing equilibrium. Drawing on the theory of planned behavior, self-determination theory, physical literacy, and closed-loop management, this conceptual study develops an integrated promotion model in which publicity, participation, guarantee, and feedback function as four coupled modules rather than as sequential administrative steps. The model specifies the internal architecture of each module, the interfaces at which coordination typically fails, and the decision rules that sustain iterative correction. A sequential mediation pathway is proposed in which kinesthetic enjoyment, social connectedness, and self-efficacy transmit the effect of practice to physical literacy and sustained exercise behavior, with perceived safety modeled as a first-stage boundary condition rather than as a mediator. A three-tier goal structure, a four-layer content sequence, and a staged application roadmap with progression gates operationalize the model under heterogeneous resource conditions. The framework contributes a mechanism-based account of how an emerging sport may be institutionalized in higher education, and identifies the empirical propositions on which such institutionalization depends.
