The Claim
In postmenopausal women, increasing the volume of resistance training leads to greater muscle hypertrophy without a corresponding increase in muscle strength, indicating that these two adaptations are regulated by distinct physiological mechanisms.
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 postmenopausal women, doing more resistance training sessions or sets builds more muscle size but does not improve strength, suggesting that muscle growth and strength gains follow different biological pathways.
See the scientific wording
In postmenopausal women, resistance training volume has a dissociated effect on muscle hypertrophy and strength, where higher volume increases muscle mass but not strength, suggesting that these adaptations are regulated by different physiological mechanisms.
Doing more sets of strength exercises makes muscle fibers grow larger by keeping them under tension longer, which tells the muscle to build more contractile proteins. But this doesn't make the nervous system send stronger signals to the muscles, so strength doesn't increase beyond a certain point.
What the research says
1 studyIn older women, doing more sets of leg exercises made their muscles bigger, but didn’t make them stronger than doing fewer sets—so muscle growth and strength gains don’t always go hand in hand.
