Children and Exercise XXV presents the latest research in the field of paediatric exercise sciences, focusing on the interaction between physical activity, exercise or sport on the one hand, and nutrition, metabolism regulation, cardio-respiratory function or muscle function on the other. Including contributions from leading international experts, the book is arranged into six thematic sections addressing: * metabolic syndrome and nutrition * hormonal and inflammatory regulations * cardio-respiratory function * children's performance * fitness assessment * physical activity. Offering a critical review of current topics and reports of contemporary research, this is a key text for all researchers, teachers, health professionals and students with an interest in paediatric sport and exercise science, sports medicine and physical education. The papers contained within this volume were first presented at the twenty-fifth Paediatric Work Physiology meeting, held in Le Touquet, France, in September 2009.
