According to WHO physical activity guidelines for the prevention and control of non-communicable diseases, what is the minimum weekly aerobic activity recommended for adults aged 18 to 64 years?
- A At least 75 minutes of moderate-intensity activity
- B At least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity activity ✓
- C At least 300 minutes of vigorous-intensity activity on 5 days
- D At least 60 minutes of moderate-intensity activity daily
Correct answer: B. At least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity activity
Explanation
WHO recommends adults accumulate at least 150 to 300 minutes of moderate-intensity aerobic activity, or 75 to 150 minutes of vigorous-intensity activity, per week, plus muscle-strengthening activity on 2 or more days. Option A reverses the intensity-duration pairing: 75 minutes applies to vigorous, not moderate, activity. The 60-minute daily figure is the recommendation for children and adolescents, not adults.
