The Claim
Overtraining syndrome lacks definitive biochemical markers for diagnosis, and current diagnostic approaches depend on a combination of subjective assessments (such as questionnaires and mood state evaluations) and objective biomarkers (including hormone levels and inflammatory markers), all of which exhibit limited sensitivity and specificity.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
There's no single blood test or clear sign that doctors can use to diagnose overtraining. Instead, they rely on a mix of how you feel (like mood and fatigue) and lab tests (like hormones and inflammation), but none of these are very accurate on their own.
See the scientific wording
There are no definitive biochemical markers for diagnosing overtraining syndrome; diagnosis relies on a combination of subjective measures (e.g., questionnaires, mood state assessments) and objective biomarkers (e.g., hormone levels, inflammatory markers), all of which have limited sensitivity and specificity.

1 studyStudy: Overtraining Syndrome as a Risk Factor for Bone Stress Injuries among Paralympic Athletes
The study says doctors can’t rely on a single blood test to diagnose overtraining and must use questionnaires and other tests that aren’t perfect—just like the claim says.
