Schools are in a unique position to help students attain the nationally recommended ____ or more of moderate to vigorous physical activity daily.

Correct option is D

The correct answer is (d) 60 minutes
Explanation:
Global and national health guidelines (such as those from the WHO and CDC) recommend that children and adolescents engage in at least 60 minutes of moderate to vigorous physical activity every day. Schools are the primary environment where this goal can be achieved through P.E. and sports.
Information Booster:
● Health Standard: The 60-minute rule is considered the minimum necessary to maintain cardiovascular health and bone density in children.
● Vigorous Activity: This includes activities that significantly increase heart rate, like running, jumping, or fast-paced sports.
● Developmental Need: Growing children require consistent physical stimulation for the healthy maturation of their muscular and skeletal systems.
● Academic Link: Meeting the 60-minute goal is linked to improved concentration, memory, and better classroom behavior.
● School Role: By providing playgrounds and scheduled periods, schools ensure that even children from inactive homes get required exercise.
Additional Points:
● Option (a): Sub-optimal – 30 minutes is often recommended for adults, but children require a higher volume of daily activity.
● Option (b): Incomplete – 45 minutes is a common duration for a school period, but it does not meet the full daily health recommendation.
● Option (c): Insufficient – 15 minutes of activity is inadequate for the metabolic and physical development needs of a growing adolescent.

So the correct answer is (d)
