The revised overall model of HFMS V1.0. Notes: The scale entries (HF1-HF36) were observed variables. P1, P2, P3, M1, M2, M3, S1, S2, PF, MF, SF were potential variables, where P1, P2, P3, M1, M2, M3, S1, S2 were endogenous variables and PF, MF, SF were exogenous variables. PF=Physical Fitness subscale, MF = Mental Fitness subscale, SF=Social Fitness subscale. P1 = Organ function, P2 = Motor function, P3 = Physical adaptive capacity, M1 = Psychological cognition, M2 = Resilience, M3 = Stress response, S1 = Role adaptation, S2 = Social resource and social support
