A perfect example of the muddled thinking regarding testosterone, advantage and sports categorisation.
‘T means better performance. It’s debatable whether that’s a sports advantage.’
🤪
‘No trans Olympians’ is not simply a function of physical capacity but also participation.
My husband has never won an Olympic medal. He should be allowed to compete with females?
We recognise doping as unfair because it confers advantage over and above ones innate capacity, and this contravenes the general principles of sport. We fight over SuperShoes for the same reason.
We recognise they have physical advantage (unavailable to the field) that makes them a better athlete *in reference to their innate capacity*.
First principles - what we know about T and the male body - tell us there is advantage, even if there is no *ability*.
‘A peak age female should be allowed to compete against 70 year old females in their age class if the skill level of the peak age female is ‘compatible’ (that is, if they finish a race at about the same time).’
@runthinkwrite may wish to extend here.
Thanks Emma. I agree with you and wanted to add another slightly different take on the Karkarzis quote. I think Karkazis is using \u2018value\u2019 and \u2018normative\u2019 in rather odd ways. Here we go: (thread) 1/ https://t.co/PEBJ3X1m6j

With Cathy's permission, I have converted the stats from this paper into graphic form.
Read on.
First, Cathy reported the numbers and % split of UK males and females playing selected sports. Male participation is higher than female participation.
Then, Cathy used population estimates to predict the numbers of male and female athletes who would be eligible, under a selfID model, for the opposite sex category. Cathy calculated these trans athletes as % of opposite sex category.
I have calculated the trans athletes as a frequency in the opposite sex category.
Here is the data for transwomen in female sports.
Here is the data for transmen in male sports.

Delighted my research article Female Sports Participation, Gender Identity and the British 2010 Equality Act is now published in Sport Ethics and Philosophy. 1/https://t.co/wNPz2sd2WD

@Hogshead3Au @BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 OK.
Fitness data from over 85k AUS children aged 9–17 yrs showed that, compared with 9 yr females, 9 yr males were 9.8% faster in sprints, 16.6% faster over 1 mile, could jump 9.5% further, could complete 33% more push-ups in 30 s and had 13.8% stronger grip.
@BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 Here is my full description of that data.
Example:
1.6km timed run (CV endurance)
The *best* 17 yr old girls are matched by *average* 17 yr old boys, and beaten, by some measure, by the best 9 yr old
@BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 Male advantage of a similar magnitude was detected in a study of Greek children, where, compared with 6-year-old females, 6-year-old males completed 16.6% more shuttle runs in a given time and could jump 9.7% further from a standing
@BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 In terms of aerobic capacity, 6- to 7-year-old males have been shown to have a higher absolute and relative (to body mass) VO2max than 6- to 7-year-old
@BARBARABULL11 @boysvswomen @cbrennansports @Martina @devarona64 Pre-puberty performance differences are not negligible, and could be mediated, to some extent, by genetic factors and/or activation of the hypothalamic–pituitary–gonadal axis during the neonatal period, sometimes referred to as “minipuberty”.
