Overtraining results from an imbalance between training load-induced fatigue and organism's recovery abilities. Its etiology is complex and to date there is no useful clinical diagnostic tool. The purpose of this review is to discuss the blood chemistry parameters potentially useful for diagnosing overtraining in athletes. ⋯ Early diagnosis of overtraining diagnosis may be established only from a battery of analyses, which should include the whole of the potential parameters. These remain unpredictable and do not allow systematic determination of new cases. Only a longitudinal study of the physiological situation appears to allow the necessary conditions for detecting overtraining in the early stages of its process for each subject.
