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.

In plain English

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.

  1. Study: Urinary N-terminal titin fragment concentration as a non-invasive biomarker of exercise-induced muscle damage in males and females

    The 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.
