Good health should be a goal of all children and adolescents, as well as the parents and guardians who care for them. Regular physical activity is part of achieving this goal. Sports can provide manifold benefits, including fitness, motor skill development, teamwork, and of course, fun. As with any pursuit that provides such benefits, however, there are risks involved, p- ticularly for growing athletes. Physicians and other health professionals caring for active children should be able to provide appropriate care and advice for sport and fitness related medical issues. This book is written as a practical guide for those of us who provide care for young athletes.
