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.
