Introduction: the role of exercise in the diagnosis and management of chronic disease in children and youth.

This symposium addresses the role of exercise testing and training in the diagnosis and/or management of chronic disease in children and youth. Four different diseases or disorders will be addressed including cardiovascular, pulmonary, neuromuscular disease, and obesity. The purpose of this symposium is to enable the exercise professional to recognize the importance of the use of exercise in the diagnosis and/or management of these chronic diseases. The papers give a brief description of the pathophysiology of the disease, and the resultant effects upon the child's response to acute exercise and to training. Each author has summarized as well as contributed original research specific to the understanding and improved care of children with these conditions. Also included are practical suggestions for the implementation of exercise testing and exercise training to enhance the care and well-being of these children. Where applicable, the authors have indicated research questions and similar recommendations for future research efforts. The purpose of this symposium, therefore, is to educate medical and exercise professionals concerning the importance of exercise testing and training in the overall care of children with chronic disease.
