The Analysis Of The Sports Biomechanics To The Spin Turn In Latin Of The Female Dancers

Research purposes:by analyzing of The Sports Biomechanics and researching the Spin turn in latin of the female dancers,i’ll establish related principles and thus provide certain theory basis.research methods:the method of the literature, theoretical analysis and experiment method, experimental method is used in high-speed photography and image analysis method.research results:1.The Spin turn force incluse the power of the player himself as well as the assistance of outer force2.The time players spent flattuening the first spin is1.120s on average,0.860s the second spin,1.160s the third spin and0.820the fourth.3.the max speed in X direction is1.340m/s,0.672m/s in the direction of Y,0.421m/s in Z, and1.425m/s in3D.4.the player’s Upper limbs moving range shows Cyclical change within4.240s. and peak of wave appear in the graph.5. The speed variation characteristics of knee and hip with side is roughly the same,and so is the trend and change characteristics.Conclusions:1.From the angle of The Sports Biomechanics, the female dancers must hold from begin to turn, turns continuously and stop turning--these three important links to finish the Latin dance in the plan turned movement and got very good effect, and the coordination of all parts of the body. In the context of the body coordinate force, the head of the body, with instant turn of the arm swing place, waist-hip crotch, and legs coordination with the power is very important, the right way is to meet the law of conservation of momentum.2.Change range of body gravity is especially important to the balanced dancing body, dancers should control in the whole body body change,which also is the focus of the deviation from range.3. In continuous athletes tours chaines action, whether it be the pendulum swing arm, or the rotation of the legs, the joint angle and the change of drying-rate of the joint present cyclical change rule, with side body angle and speed change rule similar. Athletes body parts must be coordinated in movement, to complete high stability, good quality flat spin action.
