>When prolonged, excessive training stresses are applied concurrent with inadequate recovery, performance decrements and chronic maladaptations occur. Known as the overtraining syndrome (OTS), this complex condition afflicts a large percentage of athletes at least once during their careers. __There is no objective biomarker for OTS and the underlying mechanism is unknown.__"\\ \\ Source : [[http://link.springer.com/article/10.2165/00007256-200232030-00003|The Unknown Mechanism of the Overtraining Syndrome]] in: //Sports Medicine//, March 2002, Volume 32, Issue 3, pp 185–209
