There is no clear diagnostic to identify Overtraining Syndrome, therefore Overtraining Syndrome can only be proven after all other possible explanations of the symptoms have been ruled out[1]. Early confirmation of Overtraining Syndrome is almost impossible because the only key symptom is underperformance, usually combined with Mood State changes[1]. It is important to understand that Overtraining Syndrome is not just a physiological problem, but includes aspects of psychology. An overtrained athlete is unlikely to have all of the symptoms, but they may have several. Over 90 symptoms of Overtraining Syndrome have been recorded[2].
