Cultural Differences and Movement Physiology: Studies out there?

Rolf Movement studies ( as carried out by by Rolfers ranging from Mary Bond, Jane Harringtonand Hubert Godard to Monica Caspari) look at how our perceptual style affects relationship to gravity and to our environment. These in turn give insight into the implicit perceptual bias of a given culture, by looking analytically at their movement preferences, in dance, sport, society, etc..
Has anyone done scientific studies on the psychobiology and physiology of cultural patterns in posture and movement? I don’t mean an anecdotal report that, for example, Brazilians move differently than Americans. It would seem to be somehow linked with the Gamma system of innervation, which affects the quality of our motion by receiving signals from the mid-brain. Imagery and emotions affect our muscle tone via these conduits.
