Sports performance has greatly improved in the last years. Levels of performance previously considered impossible are common today. Nowadays, the evolution of Sports Science allows for the application of high training overloads. Psychosocial agents, however, impose an extra load on the athlete. Often not taken into consideration by coaches, those events might lead athletes to states of excessive fatigue known as overreaching and overtraining, substantially impairing their performance.
Morgan et al. state that the overtraining syndrome is a multifactor phenomenon that entails intercommunication and affects the performance of the athletes (see the picture). Reference: F.Noce (2008).
