title: The relation of aerobic fitness to stroop task performance in preadolescent children.
abstract: OBJECTIVE
  We investigated the relation between aerobic fitness and interference control--one component of executive control--in 74 children between 7 and 12 yr of age.
  
  
  METHODS
  Participants completed a paper-and-pencil version of the Stroop color-word task and the FITNESSGRAM, a valid and reliable test measuring different components of physical fitness (i.e., aerobic, muscle, and body composition). During each condition of the Stroop task (word, color, color-word), participants were instructed to read aloud as many items as possible in 45 s. Data were also collected on IQ and personal and health demographics to account for other factors influencing the relationship between fitness and executive function.
  
  
  RESULTS
  Older children and those with higher IQ responded to more items correctly during each of the three conditions. Greater aerobic fitness was also associated with better performance on each of the three Stroop conditions independently of the other variables.
  
  
  CONCLUSIONS
  These findings suggest that increased levels of fitness may be beneficial to cognition during preadolescent development.
