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.

In plain English

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.

Why this might work

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.

  1. Study: Resistance Training Volume Enhances Muscle Hypertrophy, but Not Strength in Postmenopausal Women: A Randomized Controlled Trial

    For 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.
