@jamestalarico @BethStelzer What on earth is this nonsense?
@jamestalarico might want to reconsider his sources, because attempting to legislate based on TikTok pseudoscience is making people look stupid.

@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”.

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.
Read on.
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

THREAD PART 1.
On Sunday 21st June, 14 year old Noah Donohoe left his home to meet his friends at Cave Hill Belfast to study for school. #RememberMyNoah💙
He was on his black Apollo mountain bike, fully dressed, wearing a helmet and carrying a backpack containing his laptop and 2 books with his name on them. He also had his mobile phone with him.
On the 27th of June. Noah's naked body was sadly discovered 950m inside a storm drain, between access points. This storm drain was accessible through an area completely unfamiliar to him, behind houses at Northwood Road. https://t.co/bpz3Rmc0wq
"Noah's body was found by specially trained police officers between two drain access points within a section of the tunnel running under the Translink access road," said Mr McCrisken."
Noah's bike was also found near a house, behind a car, in the same area. It had been there for more than 24 hours before a member of public who lived in the street said she read reports of a missing child and checked the bike and phoned the police.
