Intensity-Dependent Effects of Acute Exercise on Executive Function

Figure 4

Correlations between cardiorespiratory fitness (VO_2peak % ranking values) and changes in BOLD responses between the two conditions. (a) Flanker task: in the moderate-intensity group, fitness correlated positively with differential BOLD response () for the contrast in one cluster with peak activation in the right insula (INS). (b) Go/No-go task: in the high-intensity group, higher fitness was associated with stronger exercise-related decreases in BOLD response () for the contrast hits in one cluster with peak activation in the right postcentral gyrus (PoCG). (c) Go/No-go task: in the moderate-intensity group, fitness correlated positively with differential BOLD response () for the contrast in one cluster with peak activation in the left rolandic operculum (ROL). (FWE-corrected on cluster level, initial voxel threshold 0.001 uncorrected).
