I foresee a future dissertation on the topic of women's arm wrestling. I mean if it's good enough for NPR to cover, some grad student should be snapping it up.
I have to admit, the topic seems a bit unusual. The story, which aired on All Things Considered, notes the similarity to roller derby and wrestling (the theatrical aspects of it). But, based on the story's main source, it seems to tip more towards that than athletics.
I suspect the same issues will arise regarding self-sexification as a seeming requirement for participation; the empowerment potential of the performance; subcultural aspects; and how the sport will be presented to the general public. Already participants are referred to, at least by NPR (tsk tsk), as "lady arm wrestlers."
