• Sommario/riassunto: Creatine and Creatine Phosphate: Scientific and Clinical Perspectives is an up-to-date summary of both the scientific and medical aspects of creatine and creatine phosphate metabolism and therapy.It covers in detail the basic biochemistry, bioenergetics and biophysics of these agents with particular emphasis on their role on the cardiovascular and muscle systems. Modern in vivo myocardial and skeletal muscle measurements are outlined, and the importance of the molecules in cardiovascular medicine, sport science and cardiac surgery are highlighted.This book is designed for
