Antecedent exercise as a treatment for disruptive behavior: Testing hypothesized mechanisms of action

This study evaluated the effects of antecedent physical exercise (AE) and a mastery task on behaviorally disturbed children's self‐concepts and rates of disruptive behaviors. In addition, we evaluated whether changes in self‐concept mediated any exercise induced changes in rates of disruptive behavior. Fifty‐eight children were randomly assigned to one of three conditions: (a) antecedent exercise (jog/walk), (b) “mastery” task (a successive improvement miniaturebasketball shooting task), and (c) no treatment control group. A week of baseline was followed by 4 weeks of treatment and, finally another week of return to baseline. Results indicated that: (a) AE produced significantly less disruptive behavior than no treatment, (b) the “Mastery” task did not produce significantly less disruptive behavior than no treatment, (c) neither treatment produced increases in self‐concept relative to no treatment, and (d) changes in self‐concept did not mediate AE induced reductions in disruptive behaviors.
