The purpose of this research is to explore if the Feldenkrais Method(ATM), a leading approach of the somatics field, is positively applicable to Royal Court Martial Arts. Three research questions were prepared to achieve the purpose of this study. As a research method, experiential description based on phenomenology was employed. The researchers of this study applied the ATM to a practical field of Royal Court Martial Arts, Pyung Soo Beop in particular for 100 days. Making the training logs, the researcher described them in a lingually representative way. The result of analysis and interpretation of the somatic data were as follows. First, what appeared on Sensory Awareness Training during the process of learning the ATM of the Feldenkrais Method, were largely categorized into three features. (1) ‘intentional exploration’-the process of recognizing intention through movement, (2) ‘relaxation and communication’- the process of delivering the intention of the movement and (3) ‘integration and arrangement’- a status that looks for and recovers a definite intention of movement. Secondly, the answers of the second research questions, were characterized by the following five features: exploration, concentration, coordination, integration, and energy. (1) ‘exploration’ is the first step to discover an accurate intention at the starting point of a motion. (2) ‘concentration’ is the step to recognize and understand the definite intention of a motion. (3) coordination is the step to recognize given information through the process of concentration, and then, to continue to look for the most effective way through a ‘coordination’ of organic movements. (4) ‘integration’ is the step to relax, transit, be aligned, and be recovered through the most efficient movement. (5) ‘ki energy’ is the last one, which not sequential, overall, so it is distinguished form the order of the other steps. Thirdly, the findings to the third research questions were as followings. (1) breathing was improved and changed to be easy, comfortable, stable, and deep. (2) coordination and balance were harmoniously improved. (3) through organic harmony of movements, the body’s alignment changed into a balancing and stable state. In conclusion, this study showed that Royal Court Martial Arts applied by ATM could improve performer’s sensory awareness ability in general, integrating function and structure by intentional movement, through which training of the Martial Arts could be improve in quality.
