Kinematics Analysis Of The Flair To Wenson Difficulty Movement Of Aerobics Gymnastics

Complete set movement of competitive aerobics in difficulty movement is an important symbol of measuring athletes technical level,is also the referee to rate one of the important factors,at the same time the difficulty action is the core of the project of competitive aerobics competition factors,difficulty level directly affect the performance of the athletes.By watching video found competitive aerobics game at home and abroad,male athletes often choose Thomas written class difficulty movement,even outstanding female athletes in the complete set of movements do the difficulty movement to enhance the competitiveness.The difficulty can not only show the athletes' physical quality,and can improve the artistic expression,because it is to promote the sports action sports biomechanics technology a key subject for the development of strong,kinematics analysis was carried out on the sports action can meet the research needs,so the paper select Thomas written difficulty movement kinematics analysis.This study using the literature material method,interview method,observation method and experimental method,analyze the athlete to complete a written Thomas' s difficulty,obtain complete action time characteristics,the center of gravity in the process of kinematics parameters,such as height,speed to the difficulty of the training and the difficulty to provide the reference and provide a theoretical basis for the project of competitive aerobics.Research conclusions:1.When it comes to the difficulty of Thomas,the single-handed support time is longer than the two hands.2.Center of gravity height in the late hands front support phase rise,and use both hands in hands supporting the stage after the floor to show up and pretty hip to reach the highest gravity center,in the subsequent phase height decreased,at the end of the Vincent phase center of gravity to a minimum.3.Cent leg Angle in the process of complete written Thomas' s difficulty in three relatively large,front support phase,after the support phase and Vince support phase.Front support phase,athletes swing leg leg Angle in the best range of 100 °to 110 °;After support phase leg Angle is the best in the range of 120 °to 140 °;Vincent support phase divide the best range of the leg Angle is 140 °to 160 °.4.Right hand support phase of the left hand and right shoulder shoulder Angle support phase of the left shoulder shoulder Angle has a certain gap,right shoulder Angle is smaller than left shoulder Angle 5 °.Right shoulder Angle is the best range of 55 °to 60 °,left shoulder is 60 °to 65 °Angle optimal range.5.The common mistake of making the difficult action of Thomas Jefferson: the feet touch the ground(the low center of gravity,the Angle of the support shoulder open,the whole rotation rate is slow);Small amount of movement(leg Angle and side stretch and lateral swing of the legs).
