The Claim
In postmenopausal women, increasing resistance training volume from 3 to 6 sets per exercise over 12 weeks causes a 6.1% increase in leg lean mass, which is significantly greater than the 2.3% increase observed with 3 sets per exercise, demonstrating a dose-response relationship between training volume and muscle hypertrophy.
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.
For postmenopausal women, doing six sets of resistance exercises per movement instead of three sets over 12 weeks leads to a greater increase in leg muscle mass, with a 6.1% gain compared to 2.3%.
See the scientific wording
In postmenopausal women, increasing resistance training volume from 3 to 6 sets per exercise over 12 weeks results in a 6.1% increase in leg lean mass, which is significantly greater than the 2.3% increase observed with 3 sets per exercise, indicating a dose-response relationship between training volume and muscle hypertrophy in this population.
When muscles are worked harder and longer during strength training, the physical stress on the muscle fibers triggers internal signals that tell the cells to build more of the proteins that make muscles contract. Over time, this leads to more of these proteins being added to the muscle fibers, making them thicker and increasing the overall muscle mass in the legs.
What the research says
1 studyFor older women, doing six sets of leg exercises instead of three led to noticeably more muscle growth in the legs after 12 weeks, but didn’t make them stronger than doing three sets.
