Take-off stage refers to take-off and landing on the take-off point, swing leg kick off the ground began to swing legs through the support, cushioning, pedal stretch, pedal off from the ground, swing leg and arm to the highest position of this stage. In the athlete to complete the take-off process, the above actions are interconnected, mutual restraint. Through the technology camera and image analysis can be found in this process due to the leg jump ground leg stretch, swing leg swing and arm swing and the connection of the above action, the athlete will be obtained in the run-up horizontal speed gradually transformed into vertical speed During the take-off stage, the body is tilted inward
