Key Messages
- Adolescents and young adults, both male and female, benefit from
physical activity.
- Physical activity need not be strenuous to be beneficial.
- Moderate amounts of daily physical activity are recommended for people
of all ages. This amount can be obtained in longer sessions of moderately
intense activities, such as brisk walking for 30 minutes, or in shorter
sessions of more intense activities, such as jogging or playing
basketball for 15 - 20 minutes.
- Greater amounts of physical activity are even more beneficial, up to a
point. Excessive amounts of physical activity can lead to injuries,
menstrual abnormalities, and bone weakening.

to 25 percent among high school students between 1991 and 1995.

effective.
- Social support from family and friends has been consistently and
positively related to regular physical activity.

What Communities Can Do

hire physical education specialists to teach them.

promote adolescents and young adults confidence in their ability to be
physically active, and that involve friends, peers, and parents.
- Provide appropriate physically active role models for youths.
- Provide access to school buildings and community facilities that enable
safe participation in physical activity.
- Provide a range of extracurricular programs in schools and community
recreation centers to meet the needs and interests of specific adolescent
and young adult populations, such as racial and ethnic minority groups,
females, persons with disabilities, and low-income groups.
- Encourage health care providers to talk routinely to adolescents and
young adults about the importance of incorporating physical activity into
their lives.
