Reflective markers were placed on their ankles, knees, hips, shoulders, elbows, wrists, in the middle of their forehead, on their clavicles and on their navel.The footage was then stripped of all features except the points of light and cut to 10-second clips which were graded by 14 women and 11 men from one (very unattractive) to seven (very attractive).A further 50 volunteers were asked to rate the same women in photographs or in film footage.The results of all three tests found that women with a body mass index of 19-23 were judged to be the most attractive, along with women with smaller waist to hip ratio, or an “hourglass shape”. When participants could not see the women but only the way their bodies moved, they tended to find the same women attractive. However, there was a strong correlation between attractiveness, and those whose walk had them taking small steps and wiggling their hips.Dr Morrison said: “The results suggested that movement is as important as static measurements in gauging attractiveness, which was surprising because everyday experience suggests you can see easily how attractive someone is from a photograph.”I’m not sure why a particular walking style is considered attractive but gait might be giving away important clues to a woman’s fitness and age – key components of reproductive health.” For the study, published in the journal Visual Cognition, 37 women with a range of body types, and all wearing leggings and t-shirts, were filmed walking on a treadmill at a steady pace.

Motion is also crucial in courtship behaviours like dancing.”Research shows that we are more likely to find a woman attractive if she wiggles her hips and takes small steps.”Because body shape preferences vary across cultures and through history, the study aimed to find out if you take away the face, what sort of clues would people use to gauge attractiveness.”Motion capture allows us to isolate movement from body shape and compare the relative importance of the two.” He added that further research was needed to find out whether the role of movement varied between cultures and whether attractiveness in motion could be faked.He said: “It would be interesting to test if people can actively change their movement to attract or deter mates.”Using such knowledge is similar in evolutionary psychology terms to a woman wearing red lipstick or eyeliner, both of which directly mimic signals of fertility, youth or health.” The attractive shape on the left, and the unattractive shape on the rightCredit:University of Portsmouth/Solent Want the best of The Telegraph direct to your email and WhatsApp?
