Make room to move.

The activity warning asks what makes a healthier day possible for young people.

THE STORY IN FOCUS

1 in 4

reported no day reaching 60

minutes of moderate-to-vigorous

activity in the previous week. [4]

A global warning with a precise meaning

WHO reported on 4 November that roughly one in four

adolescents had no day in the preceding week with at

least 60 minutes of moderate-to-vigorous physical

activity. The estimate concerns a threshold. It does not

mean that these young people did no movement at all.

Keeping that distinction visible makes the finding clearer

and avoids turning a population measure into an unfair

description of individuals. [4]

What the new analysis captures

The research drew on 389 population surveys involving

more than 3.2 million adolescents across 140 countries

and territories. WHO describes little global progress

over 15 years. Girls reported no qualifying active days

more often than boys: 28% versus 22%. Only 14%

reported meeting the threshold on all seven days. The

findings rely on reported behaviour, with the limitations

that entails. [4]

Activity is broader than organised sport

WHO defines physical activity as bodily movement

produced by skeletal muscles that requires energy. It

includes movement during leisure, transport, work and

domestic life. The wider health picture therefore

includes walking or cycling as well as play, exercise and

sport. Treating an expensive club membership as the

only route would miss much of that picture. [15]

For children and adolescents, WHO describes benefits

for fitness, bone health, cognition and mental health. Its

guidance for ages 5-17 recommends an average of at

least 60 minutes a day of moderate-to-vigorous activity

across the week, mainly aerobic, with vigorous and

muscle- and bone-strengthening activities on at least

three days. The weekly-average recommendation and

this study's count of qualifying days are related but

different measures. [15]

What an ordinary day can contain

CDC guidance for ages 6-17 describes aerobic

movement, muscle strengthening and bone

strengthening. Examples include walking and running,

climbing or push-ups, and jumping. Activities should be

enjoyable and appropriate to age and ability. The mix

matters because movement supports several aspects of

development, not merely a single fitness score. [16]
