Summary
This study investigates the immediate effects of physical exercise on attentional processes in adults diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). While prior research typically compared baseline performance to post-exercise performance, this pilot study examined attention while participants engaged in a continuous performance task simultaneously with physical activity. The research was motivated by theories suggesting that ADHD involves a hypoactive attentional system due to catecholaminergic deficits, which might be enhanced by the arousal induced by exercise. The study included 31 university students: 14 with a formal ADHD diagnosis and 17 healthy controls. Participants completed the Conners Continuous Auditory Test of Attention (CATA) twice: once while sitting at baseline and once while walking on a treadmill at 5 km/h. The CATA, an auditory continuous performance test, measured hit reaction time (HRT), omission errors (OMI), commission errors (COM), detectability (DPR), and response style. The order of administration was counterbalanced, and ADHD participants were instructed to refrain from medication on the day of the experiment. Data were analyzed using a 2 × 2 ANOVA with repeated measures to assess group (ADHD vs. control) and activity (sitting vs. walking) interactions. Results revealed significant group-by-activity interactions for reaction time and omission errors. Compared to baseline, the ADHD group demonstrated faster reaction times (25.4 ms faster) and fewer omission errors (1.46% decrease) during exercise. In contrast, the control group showed slower reaction times (15.9 ms slower) and increased omission errors (0.88% increase) during exercise. Consequently, the ADHD group’s performance, which was relatively poorer than controls at rest, improved to levels comparable to the control group during physical activity. Both groups showed increased commission errors and reduced detectability during exercise, indicating a general cost of dual-tasking, but only the ADHD group benefited in terms of speed and sustained attention accuracy. The findings suggest that physical exercise can acutely enhance attentional performance in individuals with ADHD, potentially by increasing arousal and engaging catecholaminergic systems similar to stimulant medications. The study implies that integrating physical activity, such as treadmill walking or stationary cycling, into educational or work environments could help mitigate core attentional deficits in adults with ADHD. However, the authors note limitations, including the small sample size and lack of control for physiological variables like heart rate and aerobic fitness, recommending replication in larger studies.
