The Claim
Central nervous system mechanisms, such as altered neurotransmitter activity and blunted hypothalamic-pituitary responses, in conjunction with peripheral factors including muscle endocrine dysfunction, glycogen depletion, and mitochondrial impairment, contribute to the pathophysiology of overtraining syndrome in endurance and strength-trained athletes.
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.
When athletes train too much without enough recovery, their brain and body systems—like brain chemicals, hormone responses, and muscle energy production—can go out of balance, leading to overtraining syndrome.
See the scientific wording
Central nervous system mechanisms, including altered neurotransmitter activity and blunted hypothalamic-pituitary responses, along with peripheral factors such as muscle endocrine dysfunction, glycogen depletion, and mitochondrial impairment, are involved in the pathophysiology of overtraining syndrome in endurance and strength-trained athletes.

1 studyStudy: From Fatigue to Overtraining: Beyond the Dichotomy of Structure and Function
The study explains that overtraining affects both the brain and body in ways that match the claim, like changes in brain chemicals and tired muscles.
