I'd put money on them all being the sort of women who don't play sport or if they do, play a niche sport where either physicality doesn't matter so much, or where the sport has so much engrained sexism that "cultural factors putting women off" is almost a plausible explanation.
I used to play women's football. There undoubtedly are huge cultural factors at work. For example, as the mother of a DS my experience is that approximately 50% of boys play football obsessively from when they can walk until the age it dawns on them they'll never play in the Premiership, whereas with girls it's closer to 1%. This means women's football has a much smaller pool of talent to choose from. It also explains the spectacular improvement in women's football over the last 25 years. It's gone from being a game where you could play at the top levels even if you weren't a natural athlete (the old cliché of men's pub football, the fat bloke with good ball skills - my ex's description of himself), to being a game where you have to have both at the top levels (compare the current women's world cup with the first women's FA cup to be televised). And remember the base line women's football is clawing its way back from is a 60 year ban (imposed by men in suits) on playing on FA pitches.
So I can see why some women construct this "we can catch up if we try hard enough" fairy tale. But if you look at a sport where the women's pro game has been there for 50 years, tennis, you quickly realize that there are physical discrepancies which no amount of hard work and talent remove.
And it's not just elite levels where this matters. Put a single male forward on a rugby pitch even at amateur level and the women will be coming off the pitch on stretchers.
It always strikes me as a curious contradiction that these women seem to want to say "if we admit to differences in strength and speed between men and women the whole edifice of feminism will come tumbling down" but at the same time are so ready to embrace the concept of "lady brains".
