Abstract
[Purpose] In the present study, we related verbalization of physical skills to the characteristics of skilled and unskilled subjects performing a waving movement with the upper extremities in a dance performance and investigated factors constituting physical skills. [Subjects] The skilled group consisted of five subjects, while the unskilled group comprised of nine subjects who had no experience of performing waving movements. [Methods] Each waving movement performed in this study was analyzed with a motion capture system and surface electromyograms to calculate %up-and-down movement, propagation velocities, %angular variation and %MVC. Further, the skilled subjects were interviewed to verbalize the skill of the waving movement. [Results] As compared with the unskilled group, the skilled group showed at least four types of movement characteristics and two types of these characteristics were verbalized in explanations. [Conclusion] Two types of movement characteristics, substantiated by verbalization, were found to be the probable factors constituting physical skills.
