Males who suppress T and do no exercise lose about 5% mass/strength in the first couple of years.
Males who suppress T and exercise mitigate loss and often make significant gains in mass/strength.
Small males are stronger than far larger females.
@PeterTatchell Among elite rugby players at all postions, the slowest males are only a little slower than the fastest females. The weakest males are stronger than the strongest females.
@PeterTatchell If rugby is a game for players of all sizes, strengths and speeds, do you think that the mixed England lineup would contain about 50% females?
No you don’t.
Nobody does.
Because while rugby might accommodate different physicalities, it appears to be limited *within sex*.
All your tall women who can jump much higher than us shorties - see many of them playing for the Lakers?
Why not? There’s no barrier to them joining.
Except the fact that they have female bodies.
@PeterTatchell So, are you arguing for the abolition of sex-segregated sports, or are you able to understand what the evidence shows?
That females can’t compete with males. Simple fact of life.
So we got our own sports.
@PeterTatchell You think a petite transwoman who broadly fits ‘female performance levels’ should be included.
Why not any male with the same performance levels? Why not males with naturally low T?
@PeterTatchell See, you don’t actually want to remove sex segregation in sports, you want the female category to exist but to include not just females but also those with ‘female identity’.
The category was constructed around female bodies, not gender identities.
@PeterTatchell Do you have evidence that male-typical capacity, acquired at puberty, conferred for the most part by favourable skeletal structure/levers and muscle mass/strength that can, for example, create, though the shoulder, 2.4X more power than found in females, is lost in transwomen?
@PeterTatchell You don’t, because not only does that evidence not exist, the evidence that *does* exist - 11 longitudinal studies covering hundreds of transwomen - shows minimal loss of mass/strength, and nowhere near enough loss to close the cavernous gap to equivalently-fit females.
@PeterTatchell The idea that the one thing the female body *does* excel at - quicker recovery time - can thus provide females with an overall advantage in a sport like rugby is laughable.
Let’s say I am matched in an boxing competition with a male of the same height, strength and speed. Our ‘output’ is considered equivalent, and thus the competition is deemed fair.
It is not fair.
Male physical output is a composite of two factors - male puberty and natural talent. Female physical output lacks the contribution of male puberty.
That England Rugby @EnglandRugby have affirmed inclusion of transwomen in female contact rugby, despite the scientific analysis from their governing body @WorldRugby highlighting extreme safety risks, is disappointing but not surprising.
@GMB The World Rugby argument is really quite simple.
1. Forces generated in tackles by males on females present an unacceptably high risk of head injury for females.
Evidence: Extensive modelling of head/neck forces when two weights collide, basic physics.
@GMB 2. That risk is amplified when you factor in the premise that male weight is accompanied by superior strength and superior speed.
Evidence: again, basic physics.
@GMB 3. When they suppress testosterone in accordance with sports fed rules, transwomen lose only small amounts of strength, and there is no change to their bone structure.
Evidence: 11 published cohorts (800+ transwomen) tracked for muscle/strength changes over at least one year.
Wiik et al 2020 is one of 11 longitudinal studies of mass/strength in TW (some covering over 200 subjects), before and after intervention, all well within IOC limits.
@Lux48098905@JulietLine@ChardonnayM@CStaffordSmith In total, those 11 studies cover measurements of mass and/or strength in more than 800 TW, before and after 1-3 years of treatment, all well within IOC limits.
Please don’t tell me you’ve been fooled by the coincidence of 11 studies, one of which contains 11 participants. 😂
