The Claim
In recreationally strength-trained adults, the change in urinary titin fragment (UTF) measured 48 hours after eccentric exercise is strongly positively correlated with changes in serum creatine kinase (rs = 0.73, p < 0.01), suggesting that UTF may reflect similar aspects of intramuscular disruption as the established biomarker creatine kinase.
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 fragment in your pee might show muscle damage just like a well-known blood test does — and they seem to go up together.
See the scientific wording
In recreationally strength-trained adults, the change in urinary titin fragment (UTF) 48 hours after eccentric exercise is strongly positively correlated with changes in serum creatine kinase (rs = 0.73, p < 0.01), indicating UTF may reflect similar aspects of intramuscular disruption as the traditional biomarker CK.
What the research says
1 studyThe study found that after tough muscle exercise, a protein fragment in urine (UTF) goes up at the same time as a known blood marker of muscle damage (CK), so it could be used instead of blood tests.
