REZA evidence rating A: High confidence
Methodology
Position stand
Population
Global population across the lifespan: children and adolescents (5-17 y), adults (18-64 y), older adults (≥65 y), plus pregnant/postpartum women and people living with chronic conditions or disability
Intervention
Aerobic physical activity (moderate and vigorous), muscle-strengthening activity, multicomponent (balance/strength) training, reduction of sedentary time
Findings
Adults should perform 150-300 min/week moderate-intensity or 75-150 min/week vigorous-intensity aerobic activity plus muscle-strengthening activities on ≥2 days/week. Older adults should add multicomponent activity emphasising functional balance and strength training on ≥3 days/week to enhance functional capacity and prevent falls. Globally, 27.5% of adults do not meet the recommendations.
Outcome measures
All-cause and cause-specific mortality, cardiometabolic health, cancer incidence, mental health, cognitive health, sleep, falls and fall-related injuries, physical function
Limitations
Guideline derived largely from observational evidence for many outcomes; most recommendations graded on low-to-moderate certainty evidence under GRADE; dose-response precision limited; no specific quantitative recommendations for sedentary time thresholds.
