A Review of Overtraining Syndrome (OTS)
In summary, overtraining syndrome is an entity that is not well understood and requires more research for a better understanding of its causation, pathophysiology, evaluation, and management. Recently studies have proposed using Fourier transform infrared spectroscopy as a possible way to predict changes in metabolism prior to development of symptoms; however, no clear data has been elucidated to date (Petbois et al). Other researchers such as Nederhof et al suggest psychomotor speed testing as a diagnostic test that could be utilized in the future, although, it too requires further evaluation as no clear utilization for this has been established (Nederhof et al). To date, history and ruling out other causes for symptoms remains the mainstay of diagnosis for overtraining syndrome and prevention or treatment with adequate rest post excessive exercise is the most useful management strategy to date (Meeusen et al).
