The Claim
In young adult men, a single bout of intense eccentric biceps exercise leads to an increase in the volume of the exercised elbow flexor muscle compartment by over 40% within two days, followed by a decline below baseline by 10%, with the reduced volume persisting for at least 8 weeks.
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 bicep workout, guys' arm muscles swell up a lot in just two days, then shrink below normal size and stay that way for over two months.
See the scientific wording
After a single bout of intense eccentric biceps exercise, the volume of the exercised elbow flexor muscle compartment increases by over 40% within two days, then declines below baseline by 10% and remains reduced for at least 8 weeks in young adult men.
What the research says
1 studyStudy: MR measurements of muscle damage and adaptation after eccentric exercise
The study found that arm muscles swelled a lot after tough exercise, then shrank below normal and stayed that way for weeks, just like the claim says.
