In recent years, the developmental conditions for our children and adolescents have deteriorated significantly, particularly in industrialized countries. Sensory experiences and perceptions are increasingly restricted, and movement and physical experiences are reduced to a minimum. These changes impact youth sports, but also the competitive sports of young athletes, where overload, performance drops and drop outs are common. This age group is also particularly vulnerable to the multiple stresses of training, competition, and instruction, which can lead to physical and psychological problems. Individual performance capacity and thus the ability to regenerate are often disregarded in load management.
