  • Someone sway my feelings… On one hand I’m happy about inclusion but on the other I’m worried non trans women aren’t getting a fair shake.

    Edit: or just down vote. I’m genuinely torn and hoping someone can provide some insight

    Edit 2: After some snarky comments I decided to go digging… here’s what I found initially. Feel free to post your own studies/links.

    *"For the first two years after starting hormones, the trans women in their review were able to do 10 percent more pushups and 6 percent more situps than their cisgender female counterparts. After two years, Roberts told NBC News, “they were fairly equivalent to the cisgender women.”

    Their running times declined as well, but two years on, trans women were still 12 percent faster on the 1.5 mile-run than their cisgender peers."*

    and…

    Testosterone drives anatomical and physiological sex differences in the human body (Figure 1). These sex differences can be architectural and therefore permanent, or can be influenced by adult-level, circulating testosterone concentrations, and therefore modifiable. Permanent sex differences that affect athletic performance involve the (i) brain, (ii) skeletal structure, and (iii) cardiorespiratory system. Modifiable sex differences include testosterone effects on (i) muscle mass and strength and (ii) aerobic capacity. 2022 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9331831/

    and…

    “Here, we report that current evidence shows the biological advantage, most notably in terms of muscle mass and strength, conferred by male puberty and thus enjoyed by most transgender women is only minimally reduced when testosterone is suppressed as per current sporting guidelines for transgender athletes.” 2022 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7846503/

    and…

    “A study of transgender women found their race times slowed after transitioning, but their age grades, which compare people to the best runners of the same sex and age, hardly changed, suggesting they have no advantage over non-transgender women.” 2018 https://www.science.org/content/article/scientist-racing-discover-how-gender-transitions-alter-athletic-performance-including
