Attention Improves During Physical Exercise in Individuals With ADHD.

Area of Science:

• Neuroscience
• Psychology
• Human Movement Science

Background:

• Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by inattentiveness and/or hyperactivity-impulsivity.
• Previous research on physical exercise and ADHD has primarily focused on pre- vs. post-exercise performance differences.
• The impact of concurrent physical activity on attentional processes in ADHD remains less understood.

Purpose of the Study:

• To investigate the real-time effects of physical exercise on attentional performance in adults with ADHD compared to healthy controls.
• To determine if physical activity can modulate attentional deficits during a continuous performance task.

Main Methods:

• A within-subjects design comparing performance during rest and moderate-intensity physical exercise (treadmill walking at 5 km/h).
• Participants included 14 adults with ADHD and 17 healthy controls.
• The Conners Continuous Auditory Test of Attention (CATA) was administered under both conditions, with counterbalanced order.

Main Results:

• A significant group by activity interaction was observed on CATA measures.
• The ADHD group exhibited faster reaction times and reduced omission errors during exercise compared to rest.
• Controls showed a trend towards slower reaction times and increased omission errors during exercise.
• Exercise appeared to normalize attentional performance in the ADHD group, bringing them to control levels.

Conclusions:

• Physical exercise may enhance attentional function in individuals with ADHD, potentially by increasing arousal.
• Findings suggest a hypoactive attentional system in ADHD that can be modulated by physical activity.
• Engaging in exercise could be a viable strategy to improve attention in ADHD populations.
