Is there a scientific reason there are no 230 lb-380 lb female gymnast?

I could cite the low hanging fruit reason why, but I entertain there might be something less obvious as why one never sees anything but slender or petite gymnast other than the fact the ”heavy/big” females just don’t care to do the balance beam, vault, uneven parallel bars, etc. Other than not having the desire, should a larger female want to do gymnastics are there scientific reasons that would stop her, moreover, any scientific reasons that would preclude her from performing at a world-class level if she had top ranked coaches?
