The Claim
In healthy active older adults, 12 weeks of progressive resistance training increases maximal strength by 35–36% across major lifts, regardless of baseline protein intake.
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.
In healthy, active older adults, 12 weeks of progressive resistance training increases maximal strength by 35–36% on major lifts, even when protein intake is already high.
See the scientific wording
In healthy active older adults, resistance training alone for 12 weeks significantly increases maximal strength by 35–36% across major lifts, confirming that progressive resistance training remains a potent intervention for improving muscle strength even in individuals with high baseline protein intake.
Lifting heavy weights repeatedly signals the nervous system to recruit more muscle fibers during contractions, while also triggering muscle cells to build more contractile proteins, making the muscles stronger and able to produce more force.
What the research says
1 studyOlder adults who did strength training three times a week for 12 weeks got 35–36% stronger, even if they were already eating plenty of protein. The study proves lifting weights alone works wonders for building strength.
