The Claim
Athletes with overtraining syndrome exhibit altered heart rate variability patterns, specifically elevated high-frequency power and reduced low-frequency power, compared to healthy athletes, indicating parasympathetic dominance and autonomic nervous system imbalance.
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 an imbalance in their nervous system, with their body being in 'rest mode' too much and not balancing properly with 'active mode'.
See the scientific wording
Altered heart rate variability (HRV) patterns, including elevated high-frequency power and reduced low-frequency power, have been reported in athletes with overtraining syndrome compared to healthy athletes, suggesting parasympathetic dominance and autonomic nervous system imbalance.
What the research says
1 studyStudy: Diagnosing Overtraining Syndrome: A Scoping Review
The study says that changes in heart rate patterns, like those mentioned in the claim, have been linked to overtraining in athletes, which supports the idea.
