Figure 2

The best-fitting probability of hypothetical models for the relationships and directionality among three variables of habitual physical activity IPAQ, acute exercise-induced anxiolytic effect ΔSTAI-S, and physical fitness VO2max). (A) The model b of IPAQ ↔ΔSTAI-S exhibited the highest model fitting probability (91%) among eight models (23) with three observed variables (IPAQ, ΔSTAI-S, VO2max) and eight optional neighboring paths (23). (B) The regression weight estimate is 2.518 standard errors below zero. The standardized path coefficients (SE) indicate that the IPAQ explains 14.67% of the variance in Δ STAI-S. Abbreviations: df, degree of freedom; B, estimated beta value; SE, standard error; CR, critical ratio obtained by dividing the covariance estimate by its standard error.
