yea that's what they say, but really they just want it so Sally and Jane can win more medals till their knees are bust up, and that Zoe and Rebecca are poised to take their place with working knees
Oh, I'm certain of that, but that's one of the premises on which they get the funding, and that's key.
It is quite possible and plausible that if every single elite gymnast was given the opportunity to take part in an anonymous survey, they would all say that they have tried different styles and they find that, overall, their present cut is far more accommodating of movement, and the price of wedgies and bikini waxed is well worth it. If that's so, then we can get back to gasping in amazement at their feats.
It is also plausible that some of them would like to be wearing unitards, or a leotard with more fabric, but think that wanting to have a different style of costume from the rest of the squad wouldn't go down well, and have thus figured it's better to put on what they're given and have a crack at winning. Which is not an unreasonable decision. Chance at Olympic medal in outfit that requires waxing or just giving up? Hmm, even if you'd got that far and never been presented with the choice before, I can't imagine many young women spending many hours soul-searching over it!
The problem I have here is the knock-on impact. At lower levels, young competitors don't have such a powerful incentive to just accept costumes, and so may simply quit. Especially if any of the supposed grown adults involved say, "it's the kit. If you don't like it, don't do the sport".
I think that at the higher levels, organisations have a duty to make sure that if there is anyone who does want to pick a unitard or differently cut leotard, she can. Normalisation of gear that isn't so tightly-cut would affect attitudes at lower levels, like Bertrand's daughter's club.
Thus decreasing drop-out rates, yada yada, public health, yada yada.
