Research On The Lifting Movement Technology Of The Three-person Gymnastics Project In The 2017-2020 International Competition Of Competitive Aerobics

The lifting action is a special part of the complete set of actions in the competitive aerobics collective events,which has an indispensable important position.The scoring rules of competitive aerobics are updated every four years,and each revision has a profound impact on the development of competitive aerobics.The latest version of the 2017-2020 cycle competitive aerobics scoring rules makes new requirements for the lifting action,and establishes a clear scoring standard.The unique and novel lifting action is the highlight of the whole set of actions in the collective project,which is an important way to show the art arrangement.The difficult,complex and smooth lifting action can give a strong visual impact.The variation and reorganization of the lifting time,lifting method,space utilization and other factors can improve the originality and appreciation of the lifting action,so as to improve the value of the whole set of art.This research adopts the methods of literature,video analysis,expert interview and comparative analysis,and takes the top six teams of Aerobics in 2017 World Games,2018 World Aerobics Championship and 2019 Suzuki World Cup as the research content,and makes a comparative analysis of the lifting actions of 18 teams and explores new rules The development trend of the technique in the cycle provides a theoretical basis for creating a more perfect lift.The results show that:1.The lifting time of the world's elite athletes ranges from 9 to 12 seconds,and the lifting time accounts for about 12% of the set time.The short duration of the lift is not conducive to the full display of the aesthetic feeling of the lift movement,the display of the complexity and novelty of the movement and the creation of unique creative thinking of the lift movement.When the holding time is relatively large,the utilization rate of space and time is reduced,and the coherence of the action is reduced.Meanwhile,it also has a negative impact on other actions,which reduces the display time of other actions and reduces their artistic value and ornamental value.The time of lifting is different,mainly concentrated in the display of the middle and front sections with abundant energy,which is conducive to the better display of complex and novel lifting movements,and can give the audience beautiful visual enjoyment at the best time.2.In the process of lifting(excluding upper and lower methods),top athletes are lifted 3-4 times,mainly in high space.In a higher space,the lifted athletes can better display their body posture,with good thrilling and exciting.However,in low space,the ornamental value and movement complexity of the athletes are not high,so people no longer tend to use low space;The number of shaft rotation in the lifting action is 4-6,and the movement around the vertical axis and the coronal axis is the main movement in which the top athletes can independently generate force.The addition of shoulder axis changes can make the lift action more complex and beautiful.The lift action adds the change of shaft rotation,which makes use of the rapid conversion of time and space to increase its thrilling and unique,reflects the innovation of the lift action,and at the same time can improve the artistic value of the whole set of movements.3.Methods more of the world's elite athletes to lift the base fixed action skills,complete the move to do with rotation can increase lifts the spectator and the complexity of the action,in competitive aerobics competition,innovative,unique set of movements can get higher grades,so should be conducted on lift action choreography of improve the ability of exercise,top athletes lift method;In the display phase of the lift movement,the shape changes for 2-4 times,mainly using the straight arm height of the flexibility,balance and swing 360°.The coherence and ornamental value of the lift are closely related to the height of the shoulder shaft,the shape change,the body ability,the speed and the rotation,the aerial rotation and the movement type.Side somersault and back somersault are common.Most of the lifting forms are the combination of one person supporting one person and two people supporting one person.The frequency of base transformation is 2-4 times.The change of base adds ornamental value and complexity to the lifting forms,and also reflects the tacit cooperation between athletes.
