Schematic representation of mediation results. The a-path is significant for both CRF and MVPA, and the b-paths are significant for SDRT and CVRT. Note that c and c’ are not significant (except for CRF and SDRT). Indirect mediation was significant for both predictive variables (i.e., CRF and MVPA). Data in parentheses are 95% bias corrected lower-level confidence interval and upper-level confidence interval, respectively (5000 bootstrap samples). * p ≤ 0.05, ** p ≤ 0.01. CRF = cardiorespiratory fitness; CVRT = coefficient of variation of reaction time; MVPA = moderate-to-vigorous intensity physical activity; SDRT = standard deviation of reaction time.
