The Claim

In transgender women runners, changes in training volume are positively correlated with changes in age-graded performance scores (r = 0.719, p = 0.008), indicating that increases in training may reduce performance declines following gender-affirming hormone therapy.

For transgender women runners, boosting their training might help maintain their running performance after starting hormone therapy.

See the scientific wording

Changes in training volume are positively associated with changes in age-graded performance scores in transgender women runners (r = 0.719, p = 0.008), suggesting that increased training may mitigate performance losses following gender-affirming hormone therapy.

What the research says

1 study
  1. Study: Longitudinal Performance Changes in Transgender Women Athletes Pre and Post Gender Affirming Hormone Therapy

    The study found that transgender women runners who trained more after starting hormone therapy kept more of their performance ability, which supports the idea that training helps reduce performance loss.
