Interesting links between two areas of research At first glance, sport and sleep appear to be two topics that could hardly be more different: Physical and mental peak performance on the one hand - inactivity and unconsciousness on the other. This book is dedicated to this new issue and uses various examples from sports practice to show that there are numerous points of contact here. A theoretical section at the beginning introduces the basics of sports science and sleep research, while the much larger section is dedicated to its application in a sporting environment. Among other things, the sleep behaviour of athletes is presented, including how jet lag in sport and sleep deprivation can become noticeable before sporting performances and competitions. It also deals with the dream experience of motorised actions and training in lucid dreams. The book is aimed at those interested in sports science, sleep medicine, psychology and neurology, as well as trainers and sports enthusiasts who would like to read up on the subject in more detail. Contents: The basics of sleep and the circadian rhythm Sleep of athletes Sleep deprivation and athletic performance Dream research, dream experience of athletes, lucid dreams Author: Associate Prof. Dr Daniel Erlacher, sports scientist and psychologist at the University of Bern, habilitated on the subject of sport, sleep and dreams.
