Physical activity for children

What the guideline actually says

The physical activity guidelines of the four UK Chief Medical Officers were first published on 7 September 2019 and republished on 10 July 2026. For children and young people aged 5 to 18 there are three parts:

• Moderate to vigorous activity for an average of at least 60 minutes a day across the week — activity that makes a child breathe faster and feel warmer.
• A variety of types and intensities of activity across the week, to develop movement skills, muscular fitness and bone strength.
• Minimise time spent being sedentary, and break up long periods of not moving with at least light activity. No numerical limit is set.

Two things about that are worth drawing out. The averaging is deliberate: a child who does very little on a wet Tuesday and a great deal on Saturday can meet the guideline, and the earlier formulation of sixty minutes every day was superseded. And the activities that count are broad — the official list opens with play, then walking and running, swimming, skating, cycling, active travel, sports, physical education, skipping, climbing, workouts and dancing. Active play is not a lesser substitute for sport; it is the first thing named.

The 2026 republication is worth putting in proportion. It revised the introduction, added a foreword and updated the supporting evidence for adults only; no systematic review was carried out, and the children's recommendation was not reassessed. A full review co-ordinated with the World Health Organization is expected around 2030. So the guidance for children has not been substantively revisited since 2019.

The number that was deleted

Almost every version of this guidance in circulation gives a number of days a week for strengthening activity. The current guidance gives none, and the reason is documented.

The official infographic, as published on 7 September 2019, told parents to "include muscle and bone strengthening activities 3 times per week". On 19 September 2019 that line was replaced with "activities to develop movement skills, and muscle and bone strength across the week", and the change was recorded as a correction. The evidence review behind the guidelines had found broad support for bone-strengthening activity in young people but no strong evidence for any particular number or duration.

The three-day figure nevertheless persists in several legitimate places: in the 2011 guidance these replaced, in the World Health Organization's recommendations for 5- to 17-year-olds, and — more awkwardly — in the UK's own 2022 guidance for disabled children and young people, which recommends strength and balance activities three times a week alongside a daily target of twenty minutes. Nothing published reconciles that with the general guidance for the same ages.

It also persists in degraded form. At least one UK public-sector education website still carries the pre-2019 wording, labelled as NHS material and undated, instructing that "on 3 days a week, these activities should involve exercises for strong muscles and bones". That is the likely ancestry of the "twice a week" versions that turn up in older parenting copy: the number has simply decayed in the copying. The current NHS page has it right.

One correction to the examples usually given. Bone strength comes from loading and impact — hopping, skipping, jumping, running, gymnastics, climbing. Tennis and dancing belong in that family. Walking does not: in the published typologies it appears as moderate aerobic activity and nowhere as a bone-strengthening one.

How many children meet it

Only England publishes an annual measure. Sport England's Active Lives survey of children and young people, for the academic year 2024-25 and published on 4 December 2025, covers school Years 1 to 11 in England and rests on about 130,000 self-reported responses about the previous week.

• 49.1 per cent active — meeting the average of 60 minutes a day.
• 22.5 per cent fairly active, at an average of 30 to 59 minutes.
• 28.4 per cent less active, at under an average of 30 minutes a day.

That is up 5.8 percentage points since 2017-18, the highest since the survey began, and the first increase since the pandemic. Underneath it:

• Boys 52 per cent, girls 46 per cent. The gap has narrowed from 7.1 points in 2017-18 to 5.9, and is widest in Years 9 to 11.
• By ethnic group: 53 per cent among White Other children, 52 Mixed, 51 White British, 43 Asian, 42 Other, 41 Black. Unlike the sex gap, this one has widened.
• By family affluence: 45 per cent of the least affluent children against 58 per cent of the most.
• Where two or more characteristics of inequality are present, 40 per cent, against 54 per cent where none is.
• Disability made no meaningful difference — 49 per cent of children with a disability or long-term condition against 50 per cent without. That figure covers children in mainstream education only, which probably explains why the Scottish data disagree.
• The lowest band of all is Years 3 and 4, at 42 per cent.

The survey also measures the one curriculum requirement with a number attached. About 61 per cent of children in Years 1 to 11 can swim 25 metres unaided, 3.5 points below 2017-18, and 73 per cent of Year 7 pupils meet that standard by the time they leave primary school. The youngest children have not recovered at all: Years 1 and 2 are 6.5 points down on 2017-18.

Among the activities themselves, active travel has risen sharply, from 47 to 61 per cent since 2017-18; gym and fitness activity has more than doubled, from 11 to 24 per cent; team sports are broadly flat; and swimming participation has fallen slightly.

Two gaps are worth naming. The survey measures neither strengthening activity nor sedentary time, so there is no British figure for how many children meet those parts of the guideline. And it is England only.

Of the other three nations, Scotland's health survey reports 68 per cent of 5- to 15-year-olds meeting the guidelines when school activity is counted, and 59 per cent when it is not. That is not comparable with England's figure — a household survey against a school-based pupil questionnaire, with different recall and different respondents — and setting the two side by side misleads. Scotland does publish breakdowns England does not: 61 per cent in the most deprived areas against 81 per cent in the least, and 61 per cent of disabled children against 69 per cent. Wales's school sport survey does not measure the 60-minute guideline at all; its 2022 edition reported on 2021-22, and a further round was surveyed in 2026. Northern Ireland's equivalent survey covers ages 11 to 16 only, so for primary-age children there is nothing.

Physical education, which differs in all four nations

England sets no statutory minimum amount of PE, at any key stage. The two-hour figure that circulates was a target under an earlier government, dropped in 2010; the education department described it in 2012 as "an unenforceable aspiration". It has not gone away: a charity's 2026 survey found 57 per cent of teachers reporting that their school delivers "the recommended minimum of two hours of PE each week", without naming anybody who recommends it.

What the national curriculum does require at primary level is content rather than time: at key stage 1, mastering basic movements, team games with simple tactics, and dances using simple movement patterns; at key stage 2, those movements in combination, competitive games, flexibility, strength, technique, control and balance through athletics and gymnastics, dance, outdoor and adventurous activity, and comparing performances to achieve a personal best. On swimming the duty is explicit and often misquoted: all schools must provide swimming instruction in either key stage 1 or key stage 2, and the standard is 25 metres, a range of strokes, and safe self-rescue.

The other nations are each different:

• Scotland has a government target of two hours a week in primary, and meets it — 99 per cent of primary schools comply, and 90 per cent of secondaries meet the equivalent two 50-minute periods.
• Northern Ireland makes PE compulsory from 4 to 16 and is the only nation to specify minimum content by stage — athletics, dance, games and gymnastics from the foundation stage, with swimming added at key stage 2. Its education department recommends at least two hours a week. So the same two-hour figure is live official recommendation there while being a dead aspiration in England.
• Wales does not treat PE as a standalone subject at all. It sits inside the health and well-being area of learning, and no minimum time is set.

In England the primary PE and sport premium, which funded this directly in schools, was announced in July 2026 as being phased out during 2026-27 and replaced by a partnerships network, with delivery support beginning in April 2027. No new requirement on PE time accompanied it.

The Daily Mile deserves a paragraph of its own, because it is widely adopted and the evidence is weaker than its reputation. It is about fifteen minutes of running or walking at a self-chosen pace, outdoors, on most days, during class time and in addition to PE. The figures usually quoted for it — more activity, less sitting, better fitness — come from a two-school pilot with unmatched follow-up periods, no monitoring of whether schools actually did it, and movement data from 118 children. The properly designed test, a trial across 40 schools and more than 2,000 children, found no significant effect on its primary outcome. No British evidence body has evaluated it. A document headed "published research" hosted on a Scottish government education domain turns out to be written by the programme's own foundation, undated and without caveats, and is the source of much of the surrounding copy.

What activity does, and what it does not

The official benefit list — confidence, social skills, co-ordination, concentration and learning, muscles and bones, health and fitness, healthy weight, sleep, feeling good — is published without a single citation. Tested one at a time, it holds up unevenly, and at this age in particular.

• Bones: the best supported claim. Two meta-analyses find small, statistically significant gains in bone mineral content and density from weight-bearing activity, strongest before puberty and specific to the sites being loaded. The effects are small, and the mechanism is impact, which is why the choice of activity matters more here than anywhere else.
• Attainment: weaker than presented. The Education Endowment Foundation rates physical activity at plus two months — its small band — with a mark deducted because many of the studies were not independently evaluated. A systematic review of 58 intervention studies, of which only 11 were rated high quality, called the evidence inconclusive overall, with reasonably consistent benefit only in mathematics.
• Mood: not demonstrated at this age. A 2023 meta-analysis of 21 studies found that activity reduced depressive symptoms overall — but split at thirteen, the effect among the under-13s was essentially zero and not statistically significant, while among older children it was clear. The literature is not unanimous, but on a page about primary-age children the honest statement is that this benefit has been shown for adolescents and not for younger children.
• Sleep: the official claim is contradicted. A meta-analysis of 47 studies in children aged exactly 3 to 13 found a correlation between activity and sleep of 0.02 — effectively nothing — with a weak signal for vigorous activity alone. The infographic's "improves sleep" carries no source.
• Habits that last: better supported than expected. A Finnish cohort of 3,596 children followed for 27 years found moderate to high tracking of activity from childhood into adulthood, stronger in boys, and a systematic review of sixteen such studies agreed. But tracking is an association: nothing establishes that intervening in childhood changes what an adult does.
• Team sport and social benefit: two-thirds right. A meta-analysis of sport-based programmes found small but real gains in confidence and self-esteem, and in competence including social competence — and no significant effect on connection to other people, or on character and social responsibility. So the self-esteem and social-skills half of the familiar claim survives; the teamwork half does not. The authors of the main review of this literature state plainly that causal conclusions drawn from it are conjectural, since almost none of it is randomised.

Screen time

No UK source sets a numerical screen-time limit for school-age children, and the reason is on the record rather than being an oversight. The Chief Medical Officers stated in February 2019 that the research was "insufficiently conclusive" to support guidelines on optimal amounts of screen use, and that it did not demonstrate a causal relationship with mental health problems. What they recommended instead was a precautionary approach with four specific habits: phones left outside the bedroom at bedtime, a break after a couple of hours of sitting with a screen, screen-free mealtimes, and care crossing roads.

That position has shifted for the youngest children only. In March 2026 the government issued its first national screen-time guidance for under-fives, telling parents to limit total screen time wherever possible. It does not address older siblings or screen use in schools.

The Royal College of Paediatrics and Child Health published a guide in 2019 which said plainly that no safe cut-off could be recommended, that the evidence for a threshold was weak, and that families should negotiate limits between themselves. That guide has since been archived, and the college now states that it does not formally endorse screen-time resources, pointing to material published elsewhere instead.

One assumption is worth retiring. Screens are routinely said to displace physical activity. A meta-analysis drawing on 163 papers and 254 samples of children and adolescents found the association between screen time and physical activity to be −0.08, and for video games specifically no association at all; its authors concluded that the findings gave little support to the displacement hypothesis. The two behaviours largely coexist. Reducing a child's screen time is defensible on other grounds, but it should not be expected to produce a matching increase in movement.

Safety as children begin doing things out of an adult's sight is gathered under health and safety. One common source of activity has a page of its own: trampoline safety.
