Exercise and ADHD: what the new review found

On 27th October 2026 researchers at Shenyang Sport University published a review in Frontiers in Psychology that pulled together 25 randomised controlled trials of exercise for children and young people with ADHD, involving 1,116 participants. The main finding is modest. Regular exercise was linked to better inhibitory control, the ability to stop and think before acting, which is one of the things ADHD makes hardest (Shi et al., 2026). Earlier this year a much larger umbrella review in Psychiatry Research, which brought together 45 previous meta-analyses, reached a similar conclusion (Zhu et al., 2026). Both describe exercise as a useful addition to ADHD care rather than a replacement for it, and both rate the evidence behind it as low certainty.

What the review looked at

Every trial in the review compared an exercise programme with a group that did not exercise: children carrying on with their usual activities, sitting, or watching a video. The children were aged 6 to 15 and most were boys. The exercise ranged from aerobic activity to sessions that combined movement with thinking tasks, and to mixed training. Single sessions lasted anywhere from 15 to 120 minutes, and the most common programme was three sessions a week for 12 weeks (Shi et al., 2026). The researchers looked at three parts of executive function, the mental skills that let us plan and control what we do: inhibitory control, working memory and cognitive flexibility. They also looked at internalising symptoms, meaning anxiety and low mood, and externalising symptoms, the restless or disruptive behaviour that tends to get noticed first at school.

What it found

Exercise improved inhibitory control by a small to moderate amount, and the researchers rated the certainty of that evidence as low. Internalising symptoms improved by a larger amount, but the certainty there was very low, so the result could easily change as more trials are done. Working memory, cognitive flexibility and externalising symptoms did not improve by a statistically reliable amount (Shi et al., 2026). Inhibitory control in these trials was measured with cognitive tasks, so a better score does not automatically mean calmer mornings or fewer detentions. It does suggest that the skill underneath those things can shift. The umbrella review, which works at a level above single reviews, found benefits for core ADHD symptoms and for executive function, and also for mental health, motor skills and social problems. It found no clear effect on sleep quality, body mass index or school attainment. Exercise that also made children think, and programmes run at least three times a week, produced larger effects on executive function. The certainty of evidence was low or very low throughout (Zhu et al., 2026).

Why the evidence is still weak

Of the 25 trials, the reviewers judged only one to be at low risk of bias. Eighteen raised some concerns and six were at high risk, often because they did not describe how children were allocated to groups. Most trials were small, and they identified ADHD in different ways, some by clinical diagnosis and some by screening. Because almost all participants were boys, the authors say the findings apply mainly to boys, which matters because ADHD in girls is already easy to miss. The review also excluded children who had anxiety, depression or autism alongside ADHD, and those are among the children clinicians see most often. One exploratory finding was that trials whose participants had a higher average body mass index tended to show smaller effects on inhibitory control, though the authors warn against reading much into it (Shi et al., 2026).

Where exercise fits with treatment

The researchers are clear that exercise is not a treatment for ADHD on its own. They describe medication as the first-line treatment and write that relying solely on exercise "is far from sufficient", recommending it alongside behavioural support, family guidance and psychological help (Shi et al., 2026). The umbrella review says the same: a useful addition within a wider plan, not a substitute for established treatment (Zhu et al., 2026). That matches NICE guidance. Before any ADHD treatment starts, NICE says clinicians should talk with the family about the benefits of a healthy lifestyle, including exercise, and it asks them to stress the value of a balanced diet, good nutrition and regular exercise. For children aged 5 and over, NICE recommends ADHD-focused information and support for parents first. Medication is offered when symptoms are still causing significant problems in at least one part of a child's life after changes to their environment have been made and reviewed, and methylphenidate is the first medicine offered (National Institute for Health and Care Excellence [NICE], 2018). NICE clinical guidelines are available for use in Wales but are not mandatory there, so local practice may differ.

What you can do at home

The UK Chief Medical Officers recommend that children and young people aged 5 to 18 do moderate to vigorous physical activity for an average of at least 60 minutes a day across the week, with a variety of activities, and break up long periods of sitting (UK Chief Medical Officers, 2019). That applies across the UK and is a sensible target for a child with ADHD too. Regularity seems to matter more than intensity on a single day, so three sessions a week your child will actually keep up beats an ambitious plan that lasts a fortnight. Activities that make them think as well as move, such as team sports, martial arts, dance or climbing, may help executive function more than repetitive exercise, though the evidence comparing types is still thin. Pick something your child enjoys, because a programme only helps while they keep doing it. If your child is regularly kept in at break or lunchtime as a sanction, raise it with the school's SENCO, since time spent moving may be part of what helps a child with ADHD get through the afternoon.

When to get help

Exercise is worth doing whatever the cause of a child's restlessness or distractibility, but it is not a way to find out whether they have ADHD. If attention, impulsivity or hyperactivity have been causing problems at home and at school for months rather than weeks, and they are affecting friendships, learning or family life, speak to your GP practice or your child's school about an assessment. Our guide to what happens in a private ADHD assessment explains the process step by step. If your child already has a diagnosis, talk to their clinician about adding regular exercise to the plan rather than swapping anything out.

Blip is a specialist mental health service for children and young people aged 7 to 25. If you think your child may have ADHD, or they have a diagnosis and the current plan is not working, get in touch. One of our clinicians will talk it through with you and, if it would help, arrange an assessment with a named clinician. We offer ADHD assessment and support, and you do not need a referral.
