Children and Exercise XXVII
The Proceedings of the XXVIIth International Symposium of the European Group of Pediatric Work Physiology, September, 2011

Children and Exercise XXVII presents the latest scientific research into paediatric sport and exercise science and medicine, including contributions from a wide range of leading international experts and early career researchers. The book begins with chapters devoted to the five invited keynote lectures, followed by forty-two of the peer-reviewed presentations which are arranged into five thematic sections addressing:

• exercise physiology
• physical activity and health
• exercise and medicine
• testing and performance
• young athlete and sports participation.

The forty-seven chapters offer a review of current topics and ongoing research in paediatric sport and exercise science and medicine. The book is therefore a key text for all researchers, lecturers, paediatricians, health professionals and students with an interest in the exercising child in health and disease.
