The Claim

Low-load blood flow restriction training at 30% of one-repetition maximum produces moderate hypertrophy effects in type I (Cohen's d=0.59) and type II (Cohen's d=0.67) muscle fibers in untrained males but minimal effects in females (Cohen's d=0.29-0.34), indicating sex-specific responses to this training modality.

Challenge is ahead, but a single strong supporting study can change this.

In plain English

When men do light weightlifting with restricted blood flow, their muscles grow a decent amount, but women's muscles barely grow from the same workout, showing it works differently for each sex.

See the scientific wording

Low-load blood flow restriction training at 30% 1RM produces moderate hypertrophy effects in type I (d=0.59) and type II (d=0.67) fibers in untrained males but minimal effects in females (d=0.29-0.34), suggesting sex-specific responses to this training modality.

What the research says

1 study
  1. Study: Myofiber hypertrophy adaptations following 6-weeks of low load resistance training with blood flow restriction in untrained males and females.

    The study looked at the same type of training as the claim but found no real muscle growth in men or women, saying both responded similarly, which goes against the claim that men grew more.
