A study looked at whether how much adults exercise is linked to their ADHD symptoms. Researchers surveyed 268 adults in the UK who signed up online. Most were women (200, or 74.63%), and the group leaned young and towards students. About four in ten (104) screened positive for possible ADHD on a short self-report tool, which is a screen and not a clinical diagnosis.
Overall, how active a person was showed no clear link to their total ADHD symptoms once age and other conditions were taken into account. But more activity was tied to slightly fewer inattention symptoms, and this link was small (correlation -.14). Exercise done in leisure time was also tied to slightly lower total ADHD symptoms, again a small link (correlation -.13). The strength of these links did not differ between people who screened positive for ADHD and those who did not. A person's main reason for exercising was not tied to how active they were, and the number of different types of exercise a person did was not linked to total symptoms.
The design cannot show cause or direction. The authors suggest that bringing exercise into adult ADHD care might focus on people with mainly inattentive symptoms, though they note the reverse could also be true.
