One in four adolescents worldwide reported that, during the previous week, there had not been a single day on which they accumulated at least 60 minutes of moderate-to-vigorous physical activity.
Only 14% reported reaching that level on all seven days.
Those are among the findings of A Generation Missing Out: Global Trends in Adolescent Physical Activity, 2010–2025, a new World Health Organization report published on 4 November 2026. Based on 389 population surveys covering more than 3.2 million adolescents aged 11 to 17 across 140 countries and territories, it provides the most comprehensive update on global adolescent activity levels in years.
Perhaps the most concerning finding is not that activity suddenly collapsed. It is that very little has changed.
Global adolescent physical activity levels have barely improved since 2010, and according to the WHO, no country is currently on track to achieve the global target of reducing insufficient physical activity among adolescents by 15% by 2030.
So why are so many teenagers moving so little? And if sport is part of the solution, how do we make sure young people actually want to keep playing?
Adolescence changes the way movement fits into everyday life
Young children rarely need to be told that running around counts as exercise. Movement can simply be part of play.
As they grow older, that relationship changes.
School days become more demanding. Homework and exams compete for time. Independent play becomes less common, organised activities require schedules and transport, and leisure increasingly includes digital entertainment that can be enjoyed without leaving a chair.
Research suggests that the decline in physical activity actually begins before adolescence. A recent systematic review found decreases starting during childhood, with motivation, self-confidence, screen time and academic demands among the factors associated with declining activity.
That does not mean smartphones or gaming alone explain the problem.
A major review published in The Lancet describes adolescent physical inactivity as a complex issue influenced by the interaction between schools, social environments, transport, urban design, digital behaviours and opportunities for recreation. The authors argue that meaningful change requires more than telling young people to exercise: the environments in which they live need to make movement realistic and appealing.
A teenager who has a safe route to walk or cycle to school, access to sports facilities, supportive friends and an activity they enjoy is starting from a very different position from one who has none of those things.
Sixty minutes does not have to mean sixty minutes of training
The WHO recommends that children and adolescents aged 5 to 17 accumulate an average of at least 60 minutes of moderate-to-vigorous physical activity per day across the week, mostly aerobic, while also including activities that strengthen muscles and bones at least three times a week.
But physical activity is broader than organised sport.
Walking or cycling somewhere, dancing, playing outside, swimming, running, physical education at school and informal games with friends can all contribute.
That distinction is important because the answer to low activity levels cannot simply be “every teenager needs to join a sports club”.
Not everyone enjoys organised competition. Cost, transport, availability, confidence, disability, culture and where someone lives can all affect access. A global systematic review published in 2025 found substantial variation in the barriers adolescents report when trying to be physically active, reinforcing the idea that inactivity is rarely the result of one individual choice.
Sport is therefore one part of a much bigger picture.
But it can be a particularly valuable one.
What young people gain from sport goes beyond fitness
The most immediate argument for being active is physical health.
Regular activity during childhood and adolescence supports cardiovascular fitness, muscle and bone health and physical functioning, while helping to establish behaviours that can continue into adulthood. The WHO also associates physical activity in young people with benefits for cognitive function and mental health.
Organised sport can add another layer because it combines movement with goals, relationships and a sense of belonging.
A 2026 systematic review examining 189 studies on sport participation among children and adolescents found consistent associations with higher self-esteem and life satisfaction, lower symptoms of anxiety and depression, improved interpersonal skills, prosocial behaviour and a stronger sense of belonging. Team sports showed particularly consistent psychological and social benefits.
This does not mean joining a football, rugby or basketball team is a treatment for mental health problems, nor that every young athlete will have the same experience.
It means sport has characteristics that ordinary exercise does not always provide.
There are teammates waiting at training. A coach notices improvement. There is a role within a group. Progress can be measured. A young person learns how to win, lose, make mistakes, try again and work towards something with other people.
For teenagers, those social reasons for turning up can sometimes become just as important as the physical ones.
The real challenge may not be getting teenagers into sport, but keeping them there
Signing a child up for sport is relatively easy compared with ensuring they still enjoy it several years later.
Adolescence is also a period when many young people stop participating.
A systematic review of sport dropout found that enjoyment, satisfaction, perceived competence, motivation and commitment were among the factors associated with young people remaining involved. The social environment mattered too.
That should influence how we think about youth sport.
If every session becomes an evaluation, if playing time belongs only to the strongest athletes, or if improvement is recognised only through winning, sport can gradually lose precisely the qualities that made young people enjoy it in the first place.
Competition is not the problem. For many young athletes, competition is one of sport's greatest attractions.
The question is whether competition exists alongside development, friendship, enjoyment and a realistic sense of progression.
A 13-year-old does not need to believe they are going to become a professional athlete to feel that training matters. Improving a skill, being selected for a team, travelling to a tournament, competing against unfamiliar opponents or simply feeling more confident than they did six months earlier can all provide reasons to continue.
The longer those reasons remain meaningful, the greater the chance that physical activity remains part of life rather than something left behind with childhood.
Girls are still being left behind
One of the clearest findings in the new WHO report is that girls remain consistently less active than boys.
That gap appears across regions and cannot be explained simply by different levels of interest in exercise.
Opportunities matter.
Safety matters. Access to facilities and equipment matters. The sports available at school or locally matter. So do coaching environments, representation and whether girls feel that a sporting space was designed with them in mind.
The international sporting goods industry, responding to the new WHO figures, highlighted that 28% of girls reported no day with at least 60 minutes of activity during the previous week, compared with 22% of boys. Its response specifically identified access to equipment, safe spaces, coaching and school programmes as areas requiring greater attention.
Closing the gender gap therefore requires more than encouraging girls to “be more active”.
It requires asking why opportunities are being lost in the first place and whether the sporting environments available to teenagers are genuinely welcoming enough to keep them there.
Schools have something no sports club can replicate: access to almost everyone
Sports clubs play an important role, but schools occupy a unique position because they can reach young people who might never voluntarily enter a club.
Physical education is part of that opportunity, but it does not need to be the only one.
Active breaks, extracurricular sport, safe cycling and walking routes, access to facilities outside lesson times and a broader choice of activities can all create additional opportunities for movement.
Evidence suggests that school interventions can make a difference, although there is no single solution.
A 2025 systematic review examined 34 studies designed to address barriers to adolescent physical activity. Twenty-seven, or 79.4%, reported positive effects on participation, particularly when interventions addressed psychological, behavioural and social barriers rather than focusing solely on giving young people information about exercise.
This is an important distinction.
Teenagers generally do not need a lecture explaining that exercise is good for them.
They need opportunities that fit into their lives.
Families influence activity even as teenagers become more independent
Adolescence is also the period when parental influence becomes less visible, but it does not disappear.
A meta-analysis of 112 studies found a positive association between parental support and physical activity among children and adolescents. Support can take practical forms, such as transport to training or paying fees, but encouragement and creating a positive attitude towards movement also matter.
Peers become increasingly influential too.
An international study involving more than 250,000 adolescents across 74 countries found that both parental and peer support were associated with a greater likelihood of achieving sufficient levels of physical activity.
That helps explain why the social element of sport is so relevant.
A teenager may begin playing because their parents enrolled them, but continue because their friends are there.
Sport has to compete for teenagers' time. It should not feel like another obligation
Much of modern adolescence is scheduled.
School. Homework. Exams. Travel. Social commitments. Screens. Family responsibilities. In some cases, part-time work.
Sport is competing for space within that reality.
It is therefore worth asking whether simply demanding more participation is the best approach.
If physical activity is presented only in terms of future disease prevention, the argument may feel distant to a 15-year-old. The immediate reasons can be more persuasive: enjoying time with friends, learning something new, feeling stronger, getting away from a screen, travelling with a team, playing a match or experiencing the satisfaction of improving.
The WHO's new report uses four words that are particularly relevant: opportunities to be active should be safe, accessible, affordable and enjoyable.
Enjoyable should not be treated as the least serious item on that list.
It may be one of the most important.
Because an activity can offer enormous health benefits, but those benefits depend on someone wanting to return.
Getting a generation moving will require more than sport
There is no tournament, school programme or sports club capable of solving adolescent inactivity alone.
The scale of the latest WHO findings makes that clear.
Cities need places where young people can move safely. Schools need to protect opportunities for physical activity rather than allowing them to disappear as academic pressure increases. Families need affordable options. Clubs need coaches and environments that encourage young people to stay involved, including those who are never going to become elite athletes.
And sport itself needs to remain something young people can enjoy.
That might mean competition. It might mean learning to work within a team, making friends from another club or country, discovering a new sport, or simply recognising that something difficult a few months ago now feels easier.
At youth tournaments, the score is visible. The less measurable outcomes often happen around it: independence, friendships, confidence, shared experiences and the motivation to return to training afterwards.
Those things matter because the challenge identified by the WHO is not simply getting teenagers to move for 60 minutes tomorrow.
It is creating a relationship with physical activity that has enough value to survive adolescence and continue into adult life.
If only 14% of adolescents are currently reaching 60 minutes of moderate-to-vigorous activity on all seven days of the week, there is a long way to go.
Making movement easier to access is part of the answer.
Giving young people reasons to actually want it in their lives may be just as important.
