Fig. 1.
Schematic illustration of the bidirectional relationship between physical activity/chronic exercise and executive functions/effortful control. The right arrow illustrates the causal link between regular physical activity/chronic exercise and executive functions/effortful control; that is, regularly practicing exercise leads to an improvement of executive functions and effortful control. The left arrow illustrates the causal link between executive functions/effortful control and practicing regular physical activity/exercise; that is, a high efficiency in executive functions and effortful control leads to a better adherence to exercise.
