The purpose of this study was to investigate the take-off phase of Men-strike in Kendo at two types of motion (motion 1: normal Men-strike from Chudan-no-Kamae, motion 2: Men-strike by taking a step from Chudan-no-Kamae). Take-off phase during Men-strike was analyzed by using high-speed video camera (250f.p.s) and two force platforms (250 Hz). 5 males (18-19 years of age, height 171.9±1.9cm, weight 62.4±3.4kg, 9.8±2.5 years of experience, degree 3 dan) participated in this study. Ground reaction forces (horizontal component: Fy, vertical component:Fz), the angle of the upper part of the body, the waist angle, the knee angle and the angle of the inclination of the body were measured. Fy and Fz at take-off phase were outputted by left lower limb. The waist angle at motion 2 showed high value compared with motion 1. The angle of the upper part of the body, the knee angle and the angleof the inclination of the body at motion 1 showed high value compared with motion 2. Men-strike time at motion 2 was shorter than motion 1
