Understanding the physical health benefits of exercise

Another great thing about exercise is that it can keep your body healthy. Kids who exercise often have a healthier body weight than kids who don’t exercise. Exercise makes your bones solid, improves your heart and lungs, and makes your muscles strong.

Exercise can also affect specific diseases that affect adolescents and teens. New research shows that teens who exercise regularly (about 60 minutes of brisk exercise each day) burn more calories and use blood sugar more efficiently than teens who don’t exercise. This could protect you from developing type 2 diabetes. Why should this concern you? Well, in recent years, a lot of health problems that doctors saw only in adults are now seen in young people. For example, 15 years ago type 2 diabetes was rare among adolescents, but now it accounts for almost 50 percent of new cases of diabetes in young people.

Here is something else to consider: children and adolescents who are overweight are more likely to become adults who are overweight. If you start good habits (like daily exercise) when you are young, you will be likely to continue them when you’re older.

New research shows that exercise during the teen years (beginning at age 12) can help protect girls from breast cancer when they are older. Also, regular physical activity can help prevent colon cancer later in your life.
