What is the normal amount or range for middle school students to exercise?

The recommended amount of daily physical activity for middle school students (ages 11-14) is at least 60 minutes of moderate-to-vigorous physical activity (MVPA). This doesn't mean they need to run a marathon every day. It can be accumulated throughout the day in various ways:

* Moderate-intensity activities: These activities increase heart rate and breathing. Examples include brisk walking, biking, swimming, skateboarding, dancing, and playing active games.

* Vigorous-intensity activities: These activities significantly increase heart rate and breathing. Examples include running, jumping rope, playing basketball or soccer, and hiking uphill.

It's important that this 60 minutes includes a variety of activities, including:

* Aerobic activities: Activities that improve cardiovascular fitness.

* Muscle-strengthening activities: Activities that build and maintain muscle mass and strength (e.g., push-ups, sit-ups, weight training).

* Bone-strengthening activities: Activities that build and maintain bone density (e.g., running, jumping, climbing).

There isn't a specific upper limit, but excessive exercise can lead to injury or burnout. A balance of physical activity, rest, and nutrition is crucial. It's also important to remember that individual needs and capabilities vary, so what's "normal" will differ from child to child. Parents and doctors should be consulted for specific recommendations.
