The purpose of this study was to establish a test model of badminton specific power ability based on footwork. The model could be used as a tool for testing the badminton specific power of the national players, for selection of athletic representatives and for improvement of training. The subjects were 202 senior high school and university team players representing their school for attending the national high school and university competition or even the higher level. The three kinds of basic footwork (four-corner, left-right and forward-backward) were tested. A Confirmatory Factor Analysis (C. F. A.) was used to test a hypothetic Model of Badminton Specific Power Ability. The results showed excellence in both reliability and validity.
