The Study On The Anti-bow Technique Kinematics Of The Part Of Elite Women Javelin Player In China

Javelin throw is a technical sport complex field events, it is to force as the basis, the core rate, speed and strength combined with a sport more closely. Javelin can be divided into four parts: the gun and the gun grip, approach, and finally forced, after the javelin out to maintain body balance. Javelin throw in the "anti-Arch" technology main task is to make the body to form a good athlete beyond the instrument's movements to form the best hair force posture, force of the whip for the final action to create conditions, so the process for athletes in the javelin throw in the body as "anti-bow" in various stages of technology kinematic analysis, kinematic evaluation with relevant sports technology, to identify athletes at this stage the technical reason for the existence, improve and correct the player technology, which is vital important, is the purpose of this study.Based on the player the Elite Women Javelin "anti-bow" Research shows that eight Chinese women after the javelin thrower's torso angle is relatively small, indicating athlete's body in the cross-step phase and final phase of force did not fully active back extension , of this can be an indirect response to the athlete's "anti-bow" action do not be too full, so do not move beyond the sound equipment, in the cross-step phase, the athletes lost body center of gravity of the horizontal velocity relatively large step in the cross end of the right foot forward in an instant, individual athletes right shoulder to the ground, a larger vertical distance, so that players throw the body forward and the hard side prematurely, resulting in "anti-Arch" technical irregularities, but also affect the "full bow" Movements of formation.Force in the final stage, the athletes left the ground, while the formation of double support, the athletes formed a "full bow" action is not very good, mainly because some athletes over the right leg bent backward trunk athletes is relatively small, the hip is not better Beyond the shoulder, the left is not very good braking effect. Most players left the ground hard in the last moment to slip his right foot dragging moment, the left shoulder of the braking action is not very reasonable, left hip and left knee is less the speed of change, the indirect effects of a bad brake description, not a short time to the left within the brake. Impact "full bow" formation and play technology. Thus affecting the "whipping" of the technical action. Recommendation: athletes in the cross-step left foot start to the final stage of a hard time, should be appropriately increased body tilted backward to increase the athlete's body after the dip, thus increasing the athlete as "anti-bow" shape of the magnitude of increase in acting from the . Force left the ground in the final moment, the left should be fixed in time to avoid excessive forward, hip axis remain beyond the shoulder axis, left the ground is the ground should be a reasonable angle. As the left side of the support and braking, to form a left foot athlete's body, his right foot and throwing the three power points for the completion of reasonable "full bow" to create favorable conditions for the position.
