The Claim

Transwomen, prior to initiating hormone therapy, demonstrate 31% greater push-up performance and 21% faster 1.5-mile run times compared to cisgender women under 30 years of age, suggesting a baseline athletic advantage in strength and endurance likely attributable to prior testosterone exposure during puberty.

In plain English

Before starting hormone therapy, trans women can do 31% more push-ups and run 1.5 miles 21% faster than cis women under 30 — probably because of the effects of testosterone during puberty.

See the scientific wording

Prior to hormone therapy, transwomen perform 31% more push-ups and run 1.5 miles 21% faster than cisgender women under 30, indicating a substantial baseline athletic advantage in both strength and endurance likely due to prior testosterone exposure during puberty.
