"The head, neck and upper body come out as the key features that are important for good dancing and that surprised us," said Neave, whose study is published in the journal Biology Letters. "When you see brilliant dancers, you'll see their bodies, heads and necks are all doing ever so slightly different things in time to the music."
Will Brown, a psychologist at the University of East London, said more work was needed to disentangle why dancing is attractive and its biological significance.
"When you have so much movement data from a relatively small sample of dancers, you might get chance associations between certain moves and dance attractiveness," he said.
