PURPOSE:To check the relation between the position of a ball and the body in address by detecting the load center points of the right and left legs in address, and calculating and storing the relation between the position of the load center point of each leg and the position of the ball as address information, and displaying the address information. CONSTITUTION:While a testee makes a swing the shift of the weight of the testee is detected through the detection of the load center points of both the right and left legs by right and left floor reaction meters 1a, 1b and a CPU 3 takes data on the swing from the floor reaction meters 1a, 1b with the lapse of time, and calculates the load center points of the right and left legs, thereby analyzing the swing. The CPU 3 further calculates the relation between the position of each of the load center points of the right and left legs in address, the first stage of swinging motion, and the position of a set ball. The results of those calculations are either displayed in real time on a CRT screen or displayed as address information on a CRT 4 or a printer 5 and are recorded on storage means such as a magnetic disk.
