Research On Detetion Technology Of Some Elite Chinese Women Pole Vault Athletes Run-up And Take-off

Pole vault is a technology complex of track and field events, on the player’s speed, bouncing, the ability to quickly and efficiently controlling the body’s parts have very high demands. Speed is a key technology in pole vault technique, take off in order for the body to complete the take off and leave to get good body position, achieve better takeoff effect, full up, so as to smooth over the crossbar. Paper to brace Rod high jump run-up and jump process body attitude each indicators for Center, using image measurement method and data processing on China part excellent woman brace Rod high jump athletes of run-up and jump process for shooting, and will run-up and jump process of image data finishing for kinematics analysis, find technology gap and exists problem, to for improved China excellent woman brace Rod high jump athletes of technology provides has meaning of recommends, improve training level and targeted.Using literature data, test method, data processing method of China’s two best female pole vaulter in the run-up and start of process of kinematic analysis, we draw the following conclusions:1. the elite Chinese female pole vaulter in loss of horizontal velocity in the last two steps in the run-up is too large, influence the quality and effect of the false starts; 2. approach showed better speed up the rhythm, but in general the last two steps of approaching cohesion closely enough, can reflect the players drop rods, rod moves to speed on a scale; 3. off jumping angle is large, jump in the course of the technical aspects of kicking a certain influence; 4. the elite Chinese female pole vaulter in plant is accomplished using three-step jump to take off. But needs to be further improved drop Rod technology; 5. the elite Chinese female pole vaulter in pole-and-last-step of the two-step approach is reasonable, the last step is less than the penultimate step, conducive to the completion of the subsequent suspension and swing movement. But China’s female pole vaulter’s run up faster than the world’s top athletes. Strengthening China’s female pole vaulter speed quality training to further improve speed, grasp the rhythm, minimize the loss rate of approach speed; 6. elite Chinese female pole vaulter in the push-off leg touches the ground the moment body cm horizontal velocity is small, small angle of knee, hip, and take off for poor body posture control, resulting in jumping focus when I finish the vertical speed, affect the result of jumping, high jumping height cannot be achieved.
