The relation between habitual physical activity, amygdala reactivity, and acute exercise-induced anxiolytic effect. (A) The exercise-induced amygdala reactivity to explicit fear was correlated with the IPAQ scores (r = −0.35, P = 0.029). (B) The exercise-induced amygdala reactivity to explicit fear was correlated with ΔSTAI-S (r = 0.36, P = 0.026). Individuals with more exercise-induced amygdala reactivity reported more anxiety relief.
