The Kinematics Analysis Of Rotating Motion Of Viennese Waltz

This article analyzes the kinematics of the rotating movement of the Vienna Waltz dance.At the same time,it studies the characteristics of the rotational movement,the dynamic characteristics and the movement of the Vienna Waltz dance,and establishes the related sports biomechanical parameters of the rotating movement,revealing the dancers.The movement laws and related principles of the movements provide a theoretical basis and reference for the training and teaching of the rotating movement of the waltz in the future.Research methods:It mainly adopts literature materials,expert interviews,mathematical statistics,and experimental methods.The experimental methods mainly use high-speed photography and three-dimensional image analysis.Research result:1.The force of the athlete's rotation includes the athlete's own force and external force.2.From the analysis of the displacement of the body's center of gravity in a three-dimensional space,from the beginning to the end,the height of the body's center of gravity changes into three parts.The lowest point appears in the beginning of the rotation,tending to 0 meters,the highest point appears in the middle of the action and will be the end of the position,consistent with the law of the fluctuation of the rotation of the Vienna Waltz dance.3.In a complete rotation,the movement amplitudes of the athlete's ipsilateral upper limbs(shoulder and elbow)showed periodic changes.During the movement,three peaks appeared in the graph.4.The characteristics of changes in the velocity of the lower extremities(knee joints and ankle joints)in the same side are also the same.The fluctuation trends shown in the graphs are approximately the same,and the changes are also in the same direction.Conclusion:1.Through the comparison and analysis of the experiment of six people,accordin g to the principles and requirements of the biomechanics,a high level professional ath lete(number 1)is used as the standard to draw the conclusion.From the.beginning to the end,the height change of the body center of gravity is one of the.important.factorsof the waltz dance in Vienna.The correct rise and fall will directly affect the quality of the dance.2.The 3D map of the left shoulder of the upper limb is basically the same as the left shoulder angular velocity curve,and the wave peak appears at the beginning of th e movement.The high level professional athlete(No.1)is the standard to draw the co nclusion.When the dancers do the rotation,the shoulder and elbow joints of.the entire upper limb of the body must be coordinated so as to complete the high-quality upper frame and lower limb rotation.3.The angle of knee joint displacement can be divided into three main parts.The angle of the knee joint is more obvious in the starting part of the movement.At the sa me time,there are three more obvious descending parts.In this period,the.athletes do the choreography step,the knee joint thigh and the calf angle is smaller.During the mo vement of the ankle,the image of the 3D presented four maximum values,and a concl usion was drawn from the high level professional athlete(No.1).In the course of rota tion,there is a process of flexion and extension from the stride to the ankle.The chan ge of the center of gravity can also lead to a similar problem.The more undulating we ight of the center of gravity,the more and more the ups and downs of the ankle.
