If this become accepted fact then I think it has very sinister and dangerous implications particularly in light of the recent cases where "consensual rough sex" has been used as a defence against charges of rape and murder. How could rough sex which results in death or serious injury not be consensual if the male accused of the crime did not have a physical advantage over the victim? She could have used her equal strength to stop what he was doing at anytime.
I talked about this in a thread a while ago, I think there is a real issue around how women are portrayed in film, tv and fiction.
We used to have 20th century portrayals where women were endless victims, crying and fainting, waiting for a hero to swoop in - which is an stereotypical and unhelpful narrative.
Now the pendulum has swung too far the other way and watching many shows (I previously cited The 100 as an example) you could be forgiven for thinking it's perfectly reasonable that a tiny 5ft2, skinny teen girl can take on a Dwayne Johnson lookalike in hand to hand combat and win.
I honestly think this is where some of the narrative about women training harder and overcoming weakness comes from. They see it all over media and fandoms and somehow internalise it as a truth.
It's a narrative I've noticed increasingly pushed outside of sci-fi (where a female character can be explained by mutant or super powers) and a lot of it is in the young adult genre that feature young teens/women who are not supernatural in any way but magically possess ridiculous strength and fighting ability.
