Biomechanical Analysis Of Chen Style Taijiquan Lanzhayi Stance

Wushu is an excellent traditional Chinese culture, is treasures of ethnic traditional sports, thousands of years of development so far, more and more loved by more people at home and abroad, but with the development of the times people made error awareness of Wushu boxing theory,boxing method and many other issue, making the process of development of Wushu in gymnastics tendency and dance orientation. For the purpose of better inheritance, development and communication of Wushu, QUALISYS-MCU500 Motion Capture System was used on this study to capture Lanzhayi movement of Chen Shi Taijiquan competition routine, select the five body joint angle, trunk angle, track the value of three-dimensional space during exercises; Huiyin hole in the X, Y, Z axis displacement; Huiyin hole trajectory in the XY, XZ plane projection, combined with boxing theory of different skill levels of these indicators to conduct a comprehensive comparative analysis. To be able to find key of Lanzhayi and rules of Chen Style Taijiquan movement, for authentication, for teaching, training and competition,provide data for reference and theoretical basis. Development reaserch ideas of scientific, standardized, standardization international for Wushu. The main conclusions are as follows:(1) joint angle-time curve can accurately reflect the visual quality of Taiji movements, observation and analysis is an effective indicator for the quality of tai chi movements. (2) Between professional group and non-professional group, the former group has the loose hip joints, flexibility, and strong leg supporting.(3) During Lanzhayi movement changes, the body tilt angle is relatively large, about 50°-90°range between the changes with the movement to make the appropriate changes.(4) Two trochanter midpoint can be used to define the coordinates of Huiyin point, it can be well reflected in the law of motion of Huiyin hole. (o)Huiyin hole, that is, movement called "Dang"is the key in evaluating the quality of Chen Shi Taijiquan. It proved movement rule during Chen Shi Tajiquan open step and the process of moving focus is that "Dang" to go "∽" way also under the arc and the unity of the "Dang" movement rule during Chen Shi Tajiquan open step and the process of moving focus is keeping with the requirements of boxing theory, medical knowledge, philosophical.
