Kinematics Analysis Of Artistic Movements In Artistic Gymnastics

With the continuous development of the project, the rules of the contest about artistic gymnastics which is a peculiar sport to women are constantly changing, too. In the latest rules of 2013, there will canceled the flexible/wave body difficulty motion, the flexible/wave action were incorporated into balance and twist action, so the body difficulty movement type consists of jumping, swivel, balance three kinds of movement in the rules of 2013.In the three core technologies, substantial jumps not only attract the audience’s attention but also determines the development trend of the body difficult. Therefore, this article will do a study in-depth from the perspective of biomechanics of Rhythmic Gymnastics Jumping Skill (for an example by skip) in order to meet the development trend of Artistic Gymnastics and better understanding the operation of jumping.Put the rhythmic gymnast in Shaan Xi province as experimental object in the study. From the view of kinematics——the motion characteristics of cross jump analysis technology. Use of the Qualisys infrared distance testing system with 6 cameras produced in Sweden the of the cross jump technique of motion of 5 senior athletes of rhythmic gymnastics for the high speed photography. To obtain the image data, using Qualisys Track and Manager Visual3D analysis software analysis of the data.The purpose of this study is to through the research of 5 excellent artistic gymnastics athletes cross jump and research the changes of kinematic indicators, analysis of the technical characteristics of each link, evaluation of sports techniques. In order to provide reference for athletes training. The results are as follows:(1) Take off stage, the level of loss is smaller, the horizontal velocity of the conversion rate, the size of the level conversion speed directly affects the leaps; The seed, the pedal Angle and push stude screws to large degree, the anchor starts to cause excessive body centre of gravity, the pedal Angle is too small will miss the optimal timing of stretching, push stude screws too small will make human body increases far degrees of suspension; Spread quickly in the Angle of each joint, swing leg will be enough positive; Only in this way can get enough support on the ground and fly high.(2) The empty stage, leaps Angle is larger, can increase the height of the suspension; Swinging leg swing faster, to quickly complete the air gesture, posture, hang time, and keep the air can be fully show the air attitude and good control; Center of gravity before the peak moment and knee, ankle joint should be at full stretch, increase the aesthetic feeling of air movement, and the leg control; Two legs of the opening of the biggest moment should be completed on or before gravity high, the swinging leg should actively bent falling stage, ready to be born; In order to show a correct and beautiful empty action.(3) Landing phase, hip bend should actively lead the body quickly toward the anchor, centre of gravity is highly positive, to quickly moved to within the effective bearing surface and increase stability Angle; Landing leg knee, ankle also do buckling, accordingly increase the buffer time; To complete the high stability, and the damage probability of small ground movements.
