The Claim
Athletes with overtraining syndrome exhibit blunted hormonal responses to insulin tolerance testing, including reduced ACTH, cortisol, growth hormone, and prolactin release, compared to healthy athletes, suggesting possible hypothalamic-pituitary axis dysfunction.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Athletes who are overtrained might have a less responsive stress and hormone system, which shows up as weaker hormone reactions during a special medical test.
See the scientific wording
Blunted hormonal responses to insulin tolerance testing (ITT), including reduced ACTH, cortisol, growth hormone, and prolactin release, have been reported in athletes with overtraining syndrome compared to healthy athletes, indicating possible hypothalamic-pituitary axis dysfunction.
What the research says
1 studyStudy: Diagnosing Overtraining Syndrome: A Scoping Review
The study reviews other research and confirms that some tests show weaker hormone responses in overtrained athletes, which matches the claim.
