**8. Early detection of overtraining**

Some patients may perform the prescribed exercise program too hard leading to overtraining [43, 44]. Such overload can result in fatigue and acute decreases in performance either directly after a single intense training session, or following the training. However, in the normal course of training and recovery, this overload then leads to a positive response, adaptation, and consequent improvement in performance. If the balance between overload and recovery is not managed properly, a positive training response does not occur and performance is not enhanced. To reach a true diagnosis of overtraining syndrome, it is necessary to exclude the presence of non‐communicable diseases (e.g., disorders involving the thyroid or adrenal gland, anemia, diabetes, and iron deficiency), infectious diseases (e.g., hepatitis, myocarditis and glandular fever), and other major disorders or feeding behaviors (e.g., bulimia and anorexia nervosa). In addition, Psychomotor speed: possibly a new marker for overtraining syndrome.
