Nan Quan Wushu Competition Difficulty Movement Tornado Foot Biomechanical Features 720 Degree Motion Analysis

With the rapid development of competitive martial arts, martial arts toward "high, difficult, beautiful, new, stable," the direction of development, especially the development of the implementation of the new rules make the game more difficult movements in martial arts is particularly important, and even has become the routine the core of the movement, but also a measure of the level of standard athletes. Nan Quan action appears to be simple, small and range of motion in the form of a single movement, but Nan Quan Quality and Performance difficulty completed action in the game is tied.720°spin kick is one of Nan Quan Wushu competition project difficulty level C action, the action component of a high technical difficulty, the more complicated aspects of the action. Read the research done by the previous action of Nan Quan found, basically confined to the qualitative analysis of martial arts techniques, but rarely in the regular summary of research. So the difficulty of movement exercises for athletes not only need to study the technical aspects of the operation, but also the need to conduct regular technical summary action to further enhance the scientific level of training, to improve the operation of Nan Quan difficulty whirlwind success rate of 720°foot also has practical significance.In this paper, the use of literature, three-dimensional kinematic analysis, observation, interviews, video analytic and mathematical statistics methods such as athlete’s foot cyclone Nan Quan outstanding 720°motion analysis. The entire action is divided into run-up, Jumping, vacated, landing four stages, after analyzing the following conclusions:1.Nanquan 720°spin kick action project run-up phase of the run-up generally use of Curving Approach; the last step length and speed of the take-off run-up an important impact.2. Nanquan project starts operation 720°spin kick stage gravity height of the subject’s body drop, jump height to have a good effect; changes in the angle of the hip and shoulder angle take-off, the athlete has a positive meaning to complete the action.3. Nanquan project stage cyclone feet vacated air smack timing 720°action should focus on the body’s vacated reach the highest point in time; athletes completed vacated where the legs smack action, shoulder angle changes to complete the air swivel action and an active role in the stability of the ground.4. Nanquan project operation 720°spin kick landing stage landing stage Athlete of each joint angle values are changed, to have an important role in the stability of the ground. Before landing time around, the focus on the vertical velocity change will have an impact on the stability of the ground.
