Imagining fair sport that doesn’t harm people

The thinking in 2003 & 2015 was that if you lower an athlete's T levels (of someone)who was XY chromosome that somehow that is going to match somebody who is XX.No, you're making that XY person unwell.

IMPORTANT: Reference slide from Kristen Worleys speakers presentation.

'THE WPATH STANDARDS OF CARE (SOC) WAS NEVER DESIGNED FOR APPLICATION IN SPORT'

Kristen was the 1st trans woman athlete sex verified under the IOC 2003 Stockholm Guidelines.

Similarly, Alvarez et al. found no difference in the relative cardiopulmonary capacity and mean strength of transgender and cisgender women

While longitudinal transitioning studies of transgender athletes are urgently needed, these results should caution against precautionary bans and sport eligibility exclusions that are not based on sport-specific (or sport-relevant) research.

Hamilton et al. found that, once adjusted for muscle mass, there is no statistically significant difference in the handgrip strength & lower body power of trans & cis women athletes

These data undermine the argument that trans women should be considered equivalent to c1s men, even before hormone suppression. This nuance is critical for accurate interpretation.

Similarly, Chiccarelli et al. reported that pre- GAHT trans women in the US Air Force (49.9 ± 10 push-ups) performed below cis males (54 ± 9).

For example Van Caenegem et al.found TW before starting GAHT had lower areal &volumetric bone mineral density; forearm & calf muscle cross-sectional area;lean body mass & grip strength; greater fat mass, calf & forearm fat cross-sectional area compared with cis men

Preservation of volumetric bone density and geometry in trans women during cross-sex hormonal therapy: a prospective observational study - PubMed
Although trans women, before CSH, have a lower aBMD and cortical bone size compared with control men, their skeletal status is well preserved during CSH treatment, despite of substantial muscle loss.
