Health and fitness are important issues for high school administrators, teachers, and students. Obesity is a growing concern for all ages, and it is particularly relevant for adolescents because they are at a stage in which they may be establishing habits that will last a lifetime. It is also a critical problem at this level because there is frequently limited time for physical education in the high schools. High school faculty can have an important impact by serving as role models for students, reinforcing good health habits, integrating movement into their courses, collaborating with parents and professionals, and sharing ideas about community resources and activities with their students.
