@Scienceofsport

Fifteen years in this debate (which IS
sometimes very ethically complex &
challenging, no doubt about that) has
me inclined to think a lot of people
don't care much for women's rights.
They have made their choices & then
'hide' behind pseudo-complexity to
avoid the principle.

So when you read pieces like it,some
legitimate points mixed with nonsense
straw men, you're seeing the outcome
of those choices & priorities. Who
matters? In principle, it's quite simple.
So if W's fair & safe sport matters,

This is such a myopic view of the issue.
I'm a trans woman who transitioned in the 00s. Haven't had a lick of testosterone in my body for two decades.
Throw me on a rugby field with a bunch of men and if they don't outright kill me, they will severely injure me.
I *cannot* compete with men.

Fact check:
Trans people aren’t banned from sport—no more than adults are banned from youth leagues or heavyweights from lightweight boxing. Sports rightly regulate categories for fairness & safety, and that means excluding males from women's sport.

Let’s talk ⛏ #Geoscience at the #FrenchOpen 🎾

That iconic “red clay” at #RolandGarros ?
👉 Not actually clay!

The red dust on top?
👉 Just a few millimeters!

🔎 It’s a precisely engineered 5-layer system 👇 (see image).

🧙‍♂️ The real magic is underneath! #Geology

#ScienceOfSport #Tennis

Infographic showing the five-layer structure of Roland-Garros “red clay” tennis courts.

1) The top layer is a very thin (1–2 mm) red crushed brick surface.

2) Beneath it is a 6–7 cm compacted limestone layer that forms the true playing surface.

3) Below that sits a 7–8 cm clinker layer for stability, followed by

(4) a gravel layer (>30 cm), and (5) a thick stone drainage base.

The total depth is about 70–80 cm. The diagram also notes that watering the court helps control bounce and slows play.

The multi layer system ensures a good water drainage.

There's no good evidence that you can 'smash & grab' altitude by arriving as late as possible. The effects are worst on day 1, and performance & physiology only improve thereafter. Should've been looking to as early as possible, and can thank FIFA for denying them day-of arrival

Runners on twitter; anyone know of a 'variability index' for running? I did a 55min run with strides, so pace was constantly fast/slow/fast/slow. This chart is the best I can find (using Stravistix plugin) @AppliedRunSci @Scienceofsport @marders @Letsgetrunning

This is absurd. Trans women who have ever experienced any onset of puberty are banned for life from women's rugby.
And trans men must perform a test to confirm they are man enough! https://twitter.com/Scienceofsport/status/1314596707041239044
