The purpose of the study was to compare the difference of movement time of typical Tai Chi form -Brush Knee Twist Step in Tai Chi practitioners at different stages during their years of training. Fifteen subjects were recruited and assigned to three groups according to their years of Tai Chi training. The subjects' years of training in Groups 1,2, and 3 were 2.4 0.7, 5.4 0.6, and 18.2 9.7 years, respectively (N =5 in each group). Two Kistler force platform was employed to measure the instant of touch down and take off in the selected Tai Chi form.
