During growth and development of children, body composition, predominantly fat and lean body mass, plays a central role. The body composition parameters are important determinants of child health, also in regard to obesity. This volume is a collection of articles presenting a broad scope of body composition experiments ranging from simple anthropometry to the technologically advanced technique of magnetic resistance imaging (MRI). It is an exceptional source of information on anthropometric measurements, bioelectrical impedance analysis (BIA) and other methods of body composition analysis in children. Beyond that the numerous considerations influencing the acceptability of the apparently simple BIA method in children are discussed in several contributions. Stimulating and up to date, this book is a distincitive reference for pediatricians, nutritionists, anthropologists, exercise and sport scientists as well as sport medicine specialists.
