The Study
Beyond physical exhaustion: Understanding overtraining syndrome through the lens of molecular mechanisms and clinical manifestation
We couldn't fully understand what type of study this is, so we're being extra careful about what conclusions to draw from it.
Analysis score
Maximum 5 for a narrative review.
Where the score came from
When athletes train too hard without rest, their body gets sick and stops working right.

When athletes push too hard, their performance might dip at first — but if it's 'functional' overreaching, they bounce back stronger. If it's 'non-functional,' they stay weak even after resting.
When athletes or soldiers train too much, their bodies can go into overtraining mode, which causes hidden inflammation that weakens the immune system, makes muscles shrink, messes with blood sugar, and makes them more likely to get sick.
