Postural patterns of farmers in the Ryukyu Islands

Postural patterns in everyday life were observed in the Ryukyu Islands. Postures seem to have two dimensions. In one dimension, they consciously changed their posture in the same action according to situations. In the other dimension, they took a particular posture, e.g., sitting with one knee raised, in different actions. The former may be related to the communicative aspect of posture, while the latter to the technical aspect of posture. Further, some postures, e.g., standing while deeply bending forward, could be regarded as techniques peculiar to their culture. The relation between culture and biology is also discussed with respect to postural patterns which may be related to the traditional lifestyle in Okinawa.
