Yi Jin The Competition Achievement Method 7 Diagnosis Technology For Action

In 2008, the state general administration of sports fitness qigong center to further promote health qigong, organization health experts across the country, creating a health qigong yi jin jing, health qigong wuqinxi, body-building qigong, six tactic,body-building qigong, eight period of jin and other four sets of fitness qigong competition achievement method, and in the fourth session of the sports meeting becomes sports competitions. In recent years, there are a lot of research on health qigong competition achievement method, to the competition achievement method of teaching, training and objective scientific evaluation, improve the level of training has played an important role. But the literature found that there is no about health qigong yi jin jing \ "nine ghost pull sabre potential\" sports biomechanics research. In order to make the athletes and qigong lovers can better grasp its essence, I on the basis of previous studies on the yi jin the competition pattern of \ "nine ghost pull sabre potential\" movement is analyzed, with its high quality to complete the type of key data and characteristics, in order to improve the teaching, training and evaluation and the service. This research adopts the Ariel three-dimensional image analytical system to yi jin jing competition routine first prize winner zhao agreed with learning and fitness qigong Tian Ding students elective class as test object, test their practice \ "yi jin jing competition achievement method nine ghost pull sabre potential\" action of kinematic data, test results found that:1, the entire action time should be controlled in 8 to 10 seconds. Knee lift a leg and vertical balance and the balance, the lateral balance time is the gradient of the floating,rendering from less to more to the law of the few to many. The action time of the main lift a leg in balance and on the side of the balance.2, lift a leg upright balance, zhao subscribe to learn the right leg displacement track is stable, but left leg displacement amplitude fluctuation is bigger and the body center of gravity down slightly, lift a leg that zhao agreed to learn when left knee bend.Tian Ding classmates right leg and left leg have a bending phenomenon. Support leg cannot bend in the rules of the contest, two knees, and hips should keep at 180 °. Sotraining to strengthen the thigh quadriceps and shares rectus and iliopsoas muscle static training, to strengthen the leg strength, improve the motion stability.3, knee balance, Zhao Zan and Tian Ding two human body center of gravity is slightly up from down to up, said his left leg in the process of action by the knee bend to unbend. Right knee and right ankle Angle can keep natural Angle.4, side a balance in the whole process of movements of sideways balance is an important part of the nine ghost pull sabre potential. Zhao Zan body center of gravity moves down too, but not show the frequency of the wave in the process of moving Zhao Zan on the whole the body's centre of gravity control ability is stronger. Tian Ding body center of gravity moves too fast down, control of the physical ability is poor. After Zhao Zan leg lifting a leg bend to greater than 60 degrees reached 74.7 degrees, lift a leg after Tian Ding leg flexion is 77 °. Although Zhao Zan lift a leg after Angle less than Tian Ding, but will subtract 0.1 points in the rules of the contest. So in the future teaching and training to lift a leg to the point of view to improve.decomposition, lets the student in each period of action of structure main point,combining with the meaning, characteristic, principle of theory of action, to help students do know the why, better reflects the characteristic achievement method in practice. In training, practice action itself at the same time to strengthen the quality of the special training. Evaluation process, can be penalised by quantitative motion specifications. Such as changes in joint Angle range, the range of the center of gravity moving, etc.
