Final answer:
The statement "Health experts recommend that adults engage in at least 60 minutes of moderate physical activity on most, or preferably all, days of the week and that children exercise for 90 minutes" is false. Adults should aim for 150 to 300 minutes of moderate-intensity or 75 to 150 minutes of vigorous-intensity aerobic activities per week, while children should get at least 60 minutes of moderate to vigorous activity daily (Option B).
Step-by-step explanation:
The health experts' recommendation that adults should engage in at least 60 minutes of moderate physical activity daily is false. According to the 2018 Physical Activity Guidelines for Americans issued by the Department of Health and Human Services (HHS), the correct guideline is that adults should aim for at least 150 minutes (2 hours and 30 minutes) to 300 minutes (5 hours) per week of moderate-intensity aerobic activity or 75 minutes (1 hour and 15 minutes) to 150 minutes (2 hours and 30 minutes) per week of vigorous-intensity aerobic activity.
More specifically, moderate physical activities are those that allow a person to talk but not sing during the activity, and vigorous activities are those during which a person can say only a few words without stopping to breathe. For children, it is not recommended that they need 90 minutes daily. The recommendations for children ages 6 to 17 are at least 60 minutes of moderate to vigorous physical activity per day.
Thus, the correct option is B.
