These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
20 children with ADHD in Study 1
Twenty children with ADHD and 20 matched controls performed the task switching paradigm, in which the behavioral indices and P3 component of event-related potentials elicited by task-switching were assessed simultaneously.
34 children with ADHD in Study 2
Thirty-four children with ADHD performed a task switching paradigm after 30 min of moderate-intensity aerobic exercise on a treadmill and after control sessions (watching videos while seated).
Key findings
Children with ADHD showed slower reaction times and lower accuracy than controls, with a higher global switch cost of 15.9% compared to 5.56 for controls. However, after the 30-minute exercise session, children with ADHD reduced their global task-switching reaction time cost from 373.09 milliseconds to 292.99 milliseconds. Exercise also boosted their P3 brain wave amplitude during complex trials, indicating improved attention allocation.
Methodology
In the first study, researchers compared 20 children with ADHD against 20 healthy control children on a task-switching test while recording brain activity. In the second study, 34 children with ADHD completed a similar task-switching test twice: once after running on a treadmill for 30 minutes and once after quietly watching a video for 30 minutes.
Limitations
This study did not evaluate the severity of ADHD symptoms among the participants, meaning the results might not apply to children with severe symptoms. It also does not establish long-term benefits, as the cognitive tests were conducted immediately after a single 30-minute exercise session. Finally, the researchers did not determine how different exercise types, intensities, or durations might affect cognitive flexibility differently.
