World Health Organization 2020 guidelines on physical activity and sedentary behaviour
British Journal of Sports Medicine · 2020
WHO's 2020 update gives clinicians concrete activity dose targets for every population, including pregnancy and chronic disease, but still won't say how much sitting is too much.
Die Studie
WHO consensus guideline update, produced by an expert Guideline Development Group synthesising and updating systematic reviews across children, adolescents, adults, older adults, pregnant/postpartum women, and people with chronic conditions or disability.
Was sie fanden
Adults are recommended 150-300 min/week moderate-intensity or 75-150 min/week vigorous-intensity aerobic activity plus muscle-strengthening on ≥2 days; children/adolescents an average of 60 min/day moderate-to-vigorous activity; sedentary behaviour should be reduced across all groups, but no quantified time threshold is given because the evidence was judged insufficient to set one.
Die Bewertung
This is a guideline synthesis, not a primary study, so 'risk of bias' means evaluating the underlying systematic reviews and GDG process rather than a single trial's methods. The dose thresholds are broad ranges rather than precise prescriptions, reflecting genuine heterogeneity in the source literature, and the explicit refusal to quantify a sedentary-behaviour cutoff is an honest acknowledgement that the evidence doesn't support one — a strength, not a weakness, of the document.
Die Lücke
No dose-response threshold for sedentary behaviour was defined, and the aerobic activity ranges are population-wide averages that don't account for individual variation in baseline fitness, injury status, or chronic disease severity — clinicians still have to individualise.
Referenzstudie
This updates the WHO's 2010 physical activity guidelines and sits alongside contemporaneous national efforts (e.g. the US 2018 Physical Activity Guidelines Advisory Committee report) that underpin the broader 'exercise is medicine' evidence base; it does not contradict prior guidance, it extends it with new population-specific recommendations.
Was am Montag zu tun ist
Yes — clinicians can use these exact thresholds (150-300 min moderate or 75-150 min vigorous weekly, plus twice-weekly strengthening) as concrete, quotable targets when counselling patients, including previously under-addressed groups like pregnant/postpartum women and those with chronic conditions or disability.
