The Claim
In recreationally strength-trained adults, the change in urinary titin fragment (UTF) measured 48 hours after eccentric exercise is strongly negatively correlated with changes in potentiated twitch force (rs = -0.77, p < 0.01) and evoked maximal rate of force development (rs = -0.62, p < 0.01), indicating that UTF may serve as a biomarker reflecting peripheral neuromuscular dysfunction following exercise-induced muscle damage.
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.
After a tough workout, a protein found in your pee might show how much your muscles are struggling to recover — the more of it there is, the more your muscle power seems to drop.

What the research says
1 studyThe study found that higher levels of a muscle protein in urine after tough exercise were linked to weaker muscles and slower strength response, which supports the idea that this protein can show muscle damage.
