The Claim
In 6-month-old male mice with constitutive myostatin inactivation, specific maximal power is reduced compared to wild-type mice, indicating that increased muscle mass does not translate to improved power output per unit of muscle tissue.
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.
Mice genetically engineered to have more muscle mass produce less power per gram of muscle compared to normal mice.
See the scientific wording
In 6-month-old male mice with constitutive myostatin inactivation, specific maximal power is reduced compared to wild-type mice, indicating that increased muscle mass does not translate to improved power output per unit of muscle tissue.
When the myostatin gene is turned off, muscles grow much larger because more muscle fibers form and get bigger. But the muscle doesn't add enough of the proteins that make it contract strongly, so each gram of muscle becomes weaker and less efficient at producing power. This means even though the muscle is bigger, it can't generate as much force or power for its size.
What the research says
1 studyIn mice that can't make myostatin, their muscles get bigger, but each gram of muscle doesn't work as well—so they're stronger overall, but not more powerful for their size.
