The Claim

In untrained individuals, females accumulate greater total resistance exercise volume than males during 8 weeks of isotonic and eccentric quasi-isometric training of the elbow flexors, but this does not result in significantly greater improvements in muscle thickness or strength.

Description
1 study reviewed
In plain English

Over an 8-week training program targeting the elbow flexors, untrained females performed more total resistance exercise volume than untrained males, but both groups showed similar increases in muscle thickness and strength.

See the scientific wording

In untrained individuals, females accumulate greater total resistance exercise volume than males during 8 weeks of isotonic and eccentric quasi-isometric training of the elbow flexors, but this does not result in significantly greater improvements in muscle thickness or strength.

Why this might work

Even though women do more total work during training, their muscles grow and get stronger at the same rate as men because both sexes reach a similar biological limit for how much muscle can adapt in a short time, regardless of how much extra effort is put in.

  1. Study: Isotonic Resistance Exercise Outperforms Eccentric Quasi-Isometric Resistance Exercise for Increasing Elbow Flexor Muscle Thickness and Estimated One-Repetition Maximum in Untrained Individuals: Exploring the Influence of Sex and Volume.

    In this study, women did more total lifting than men over 8 weeks, but both men and women ended up with similar muscle growth and strength gains — so doing more work didn’t give women an extra advantage.
