Take-off skill is one of the most important part in half-pipe snowboarding which directly determined the flying height, flying time, even the quality of motion. Study on the kinematic parameters of take-off stage of some master-standard athletes for the purpose of researching on the factors influencing the take-off skill by means of literature review, biomechanics theory, the movement-image analysis, statistics, expert interviews as well as combining the characteristics of this event. The results shows that gravity velocity, joint angle, angle and speed between board and horizontal level will have some influence on take-off skill. Suggestions are made that body should be well positioned before take-off; the center of the gravity position should be well controlled; the effective take-off angle should be kept effectively.
