Sport specialization in young athletes.

Many young athletes are pursuing high-intensity training and choosing to specialize in a single sport before high school. However, a growing body of literature suggests that this approach places children and adolescents at increased risk for physical and mental harm, and does not confer the desired benefit in the development of sport-specific skills. This article reviews concerns associated with early sport specialization, outlines principles of developmentally appropriate physical activity and athletic development, and provides practical guidance and resources to assist clinicians in counseling young athletes and their families.
