This paper deals with the force measurement by the system installing force sensors for clarifying the mechanism of Ollie motions, and the motion analysis was conducted by using the applied force indicating the advantage of Ollie motion in snowboarding. We used the measurement system for applied force（ 3-axis force and 3-axis moment）of snowboarder in the previous studies. The measurement system installs the four 3-axis compact force sensors on the sole of feet（ total 8 devices for both feet）. Furthermore, this system was improved as simply measurement system by using the compact data logger for the jump kicker experiment. We conducted the motion measurement of snowboarder on the gentle snow slope and the snowboard jump kicker using the measurement system, and we analyzed by focusing the force and moment of right and left feet and total force of moment. These analytical results indicated the difference of the Ollie motion conducted on the gentle snow slope and the snowboard jump kicker, and the importance of Ollie motion was represented. These results can be used for clarifying the mechanism of Ollie motion and the teaching of snowboard jump.
