Study On The High Level Aerobics Athletes Scissor Jump Turned Swivel 180° Action

This paper uses three-dimensional measurement method,mathematical statistics,literature method,expert interview method and so on,to get our college An-ping and Lu Lu two Aerobics Team National master athletes' scissor turned jump swivel 180°action related parameter data,and by using the method of quantitative and qualitative analysis,and identify the action the advantages and disadvantages,and find problems where to find improvement movement better for the ways and methods of quality,also can make the training more standardized and scientific,to avoid the occurrence of sports injury,to provide a feasible theory basis to further promote the development of sports training and guidance of modern science practice training.The following conclusions are drawn from the analysis:First,scissors jump turned swivel 180° moves in time on the close contact of Competitive Aerobics athletes,stretch in the take-off buffer and pedal,and body posture will affect the quality of the air movement air effect,and will cause the influence on the stability of landing.Second,in the take-off stage,scissor jump turned swivel 180° action for athletes in the run-up to after the stretch,ankle,knee,hip angle should be appropriate,and in turn bending buffer.The maximum buffer moment,An-ping knee angle is 148.76 degrees,Lu Lu's knee angle is 133.58 degrees,two athletes knee angle greater than130 degrees,can let the pedal better.Third,the center of gravity of the highest moments in the empty stage,An-ping's trunk Angle up to 172 degrees,and Lu Lu's trunk Angle up to148 degrees,illustrates the man in the process of doing this action showed better stability.In the swivel 180° times,twisting hip actively,driven to rotate the trunk and lower extremities.Upper body athletes,lean forward,and try to straighten the knee straight and feet and contribute to the formation of beautiful air posture.Two athletes in the time,the maximum angle is vacated after the emergence of the highest point of the center of gravity of the body,the maximum angle is not vacated and athletes body weight height appeared at the same moment.Fourth,on the landing stage,in order to let the athletes landing more stability and security,to prevent the occurrence of sports injuries,basically are recommended to take from the ball of the foot gradually transition to the whole foot way.Fifth,in view of the result,An-ping and Lu Lu two athletes basically realized180 degree rotation,hip,knee and ankle joint angle control properly,meet the requirements of the difficulty movement of Competitive Aerobics Rules,and high quality standards to perfect the completion of action,showing a characteristic as high athletes have.
