Quote from: MaryT on February 09, 2025, 01:49:28 AMIt is a very thorny subject. I think that transgender athletes have as much right as anyone else to express themselves through their physical abilities. However, it is difficult to PROVE that being AMAB does not confer any advantages in most sports.
...
Difficult but not impossible. A good sport to start with would be boxing, with which the anti-trans-in-sports brigade seem to have a particular problem. For example, on the website
We Need to Refer to Male Athletes as MaleMartina Navratilova presents her arguments, some of which, from the title onwards, readers may find distressing. One of her relevant "scientific" arguments against transgender women competing in boxing is
" A man's punch is 162 percent stronger than a woman's."
That may well be true. One reason is that the average man is significantly larger and heavier than the average woman. However, boxers are usually matched against opponents of similar weights, so that advantage would be significantly reduced even if a cisgender man fought a cisgender woman. (An exception might be in the heaviest category if their is no upper limit to the weight but that problem can exist even when superheavyweight male boxers fight each other.)
Another reason is that men tend to be more muscular than women. However, transgender women have hormone balances similar to those of cisgender women and typically lose much of their muscularity and strength, particularly in the upper body. Besides, Martina herself proved that women can develop physiques so muscular that many cisgender male athletes must envy them.
I am sure that those reasons are enough make Martina's statement about punching power irrelevant. However, it is one of the alleged advantages that could be scientifically tested.
As for her arguments about chromosomes, they are relevant only to those who want them to be. Definitions of men and women existed before chromosomes were discovered and chromosomes do not have to define male and female. Besides, the reason that cisgender men do not compete against cisgender women is because cisgender men sometimes have a physical advantage,
not because their chromosomes are different. In sports where transgender women do not have a physical advantage, there is no good reason why they should not compete against cisgender women.
