Overtraining syndrome (OTS) is diagnosed retrospectively through the exclusion of organic diseases and other stressors, as no single diagnostic marker currently exists to definitively identify it.
If you are an athlete experiencing prolonged performance decline and fatigue, do not look for a single 'overtraining test.' Instead, work with medical professionals to rule out other causes like anemia, thyroid issues, or infections. Focus on identifying and managing non-training stressors (sleep, life stress) and ensuring adequate nutrition, as these are key contributors to the syndrome.
Therefore, if no explanation for the observed changes can be found, OTS is diagnosed. Early and unequivocal recognition of OTS is virtually impossible because the only certain sign is a decrease in performance during competition or training. The definitive diagnosis of OTS always requires the exclusion of an organic disease... Other major disorders or feeding behaviors such as anorexia nervosa and bulimia should also be excluded.

- Non-functional overreaching (NFOR) is a distinct stage from overtraining syndrome (OTS) characterized by a stagnation or decrease in performance that resolves with sufficient rest, whereas OTS involves prolonged maladaptation and may take months or years to recover.Good
- Basal (resting) hormone measurements, including cortisol and testosterone/cortisol ratios, are not useful for diagnosing overtraining syndrome or distinguishing between well-adapted and overtrained athletes.Good
