The Claim
A single session of eccentric knee-extension exercise transiently reduces maximal isometric and dynamic knee extension strength by approximately 10% and doubles serum creatine kinase levels in fit young males, indicating acute muscle damage, but these effects recover fully within 3 weeks of training.
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.
One session of eccentric knee-extension exercise temporarily reduces knee strength by about 10% and increases a blood marker of muscle damage by 100% in healthy young men, but these changes return to normal after three weeks of continued training.

What the research says
1 studyAfter one tough knee exercise, young men temporarily lost about 10% of their leg strength and had a spike in a muscle damage marker, but after three weeks of training, they got even stronger than before. The study confirms this pattern.
