Comparative Study Of Competitive Martial Arts Routine With The Revolving Revolving Based On Three-dimensional Data

Martial arts as an experienced thousands of years of history of the Chinese nationtradition sports items, for thousands of years of history in order to adapt to the missionentrusted to it by the experience, a variety of baptism, and formed a distinctive differentschools of martial arts.From ancient times to the martial arts research mostly focuses onthe theoretical level, rarely conduct a detailed analysis of the use of modern technology.This paper studies the butterfly and the butterfly twist is a comparison of the two basicflight movements of Wushu, their biomechanics research can we better understandingbasic principles of Wushu soars the movement, but also a solid foundation for learningand practice more difficult than their flight movement. Only grasp the base crules, handyto application in practice. In addition to such research innovation on the martial arts hasa certain theoretical significance.Biomechanical analysis of butterfly and butterfly twist,the key data, see the pattern, can let the ordinary martial arts lovers or students moreeasily understand the action essentials, so as to learn the beautiful but difficultmovements, no longer let these actions has become a unique professional athlete’smovement, which has significance for the popularization of Wushu and communication.This article through the literature material method,3D motion analysis method,expert interview method, mathematical statistics method of Wushu in butterfly andbutterfly twist comparative analysis. Conclusion and suggestion:1. The height of the right leg swing and braking time, has a great influence on thevertical axis of rotation, in tion phase, right leg to the high place, and to finish spinor injump start braking, this will increase the longitudinal axis of rotation; After the empty rightleg swing speed to try to reduce, reduce the loss of momentum to increase the verticalaxis of rotation.2. After the attitude of the limbs and head of suspension movement influence thevertical axis of rotation, jump in the process of the air of complete spinor later, head toswing to the left, two legs straight and close together, the two folded arms in his chest, soby reducing the rotation radius and air kinetic energy loss to increase the vertical axis ofrotation.3. During tion higher center of gravity and the magnitude of the changes will alsoaffect the longitudinal axis of rotation, upon completion of spinor twist is that the size ofbody center of gravity change should not be too big, from step leapfrog to jump the amplitude of the instant center of gravity should change should be controlled in9.7%.4. The spinor and spinor swivel the differences on the completion time, differencelies mainly in the time when the stretching and air are different. Spinor best finish time at1.5+0.03s of spinor best finish time at1.4+0.10s.5. Both spinor and spinor swivel tion in the penultimate step will use the slide withfork step technique than better improve the quality of our action, the slide technologyeven spinor quality is not high, the completion of spinor also can have higher quality, butthe fork step technology is not.6. Spinor and the differences of spinor step by step jumping long, optimal steplength are0.38+0.01+0.04m and0.41m to complete the spinor swivel is a relativelylarge step leapfrog step length. A larger step, that may increase the vertical axis ofrotation7. Jump moments of spinor and spinor takeoff leg there are many differencesbetween the hip Angle, Angle of spinor than spinor rotation Angle is small, smaller left hipAngle is helpful to finish the horizontal axis of rotation, and relatively large left hip Angleis beneficial to complete the vertical axis of rotation. Swivel yes best Angle should bearound133degrees.8. Upon completion of spinor and spinor rotational movement, especially in theprocess of teachers’ teaching should pay attention to the points: First, when training tostrengthen the training of the waist abdominal muscle group of power, so aftercompleting of spinor and spinor can provide larger swivel rotational energy. Second, atthe completion of action is the main conscious control body posture, hold your head high,when you finish the spinor outreach as far as possible, two arms two legs are apart thehigh place, form the back arch action, this is advantageous to the horizontal axis ofrotation. Is complete the spinor swivel head to swing to the left, legs straight, as far aspossible and together, this body posture is to increase the vertical axis of rotation of thekey factors. Third,teachers in teaching should use spinor and comparison of variousstages of spinor for teaching, let the student know by comparing different, better able tofinish the two actions.
