The Claim
Transwomen under 30 years old who have undergone 12 months of feminizing hormone therapy retain a 9% faster mean run speed compared to cisgender women of the same age group, despite no longer showing performance advantages in push-up and sit-up tests, indicating that one year of testosterone suppression may not fully eliminate endurance-related performance differences.
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.
Trans women under 30 who've been on hormone therapy for a year are still 9% faster at running than cis women the same age, even though they've lost their edge in push-ups and sit-ups. This suggests that one year of hormone treatment might not completely level the playing field for endurance sports.
See the scientific wording
Transwomen who have undergone 12 months of feminizing hormone therapy retain a 9% faster mean run speed compared to cisgender women under 30 years old, despite losing their initial advantages in push-up and sit-up performance, suggesting that testosterone suppression for one year may not fully eliminate endurance-related performance differences.
What the research says
1 studyThe study shows that after one year of hormone therapy, transwomen are about as good as cisgender women at push-ups and sit-ups, but still slightly faster runners, which matches the claim.
