Reconceptualizing the Kinetic Lineage of Traditional Korean Subak: "Ttang-balbgi" (Ground-Stepping) as a Manifestation of Northern Eurasian Body Culture

This paper reexamines the foundational stepping mechanics, known as "Ttang-balbgi" (Ground-Stepping), preserved in the traditional Korean martial art Subak. Rather than confining this practice to a isolated domestic combat technique or a specific geopolitical origin, this study adopts an anthropological and biomechanical framework to position it within the macro-concept of Northern Eurasian Body Culture. By investigating trans-regional parallels—such as the "Degig" ritual in Mongolian Bökh, the rhythmic stepping in the Bukcheong Lion Mask Dance, the "Shiko" mechanics of Japanese Sumo linked to the migratory Haji/Tosa clan, and ancient earthen engineering practices—this paper demonstrates a shared regional methodology of utilizing ground reaction force. This approach provides an academically secure and globally scalable framework for archiving Subak as an Intangible Cultural Heritage (ICH).
