Contrastive Research On Lifts Between Chinese And Foreign Elite Athletes In Aerobic Gymnastics Under The Edition Code Of Point

Lift is one of the most important contents of group project in aerobic gymnastics which is an important bridge to reflect the relationship between athletes.Lift plays a crucial part in aerobic gymnastics.The 2017 edition code of point first gave the lift score,and the highest score is 1 point,which means the lift is a bright spot in the new cycle rules.Through literature,expert interview,questionnaire,video analysis,comparative analysis and mathematical statistics,the study comparethe use of scoring points,the quality of the design and completion in the 2017 National Aerobics Championship adult athletes group and the World Aerobics games(a total of 36 sets),in order to summarizes the advantages and problems of the excellent athletes in our country and provide reference for Chinese coaches and athletes to create high scores of lifts.The conclusions are as follows:1.In entry and exit of ligt,there is no obvious difference between Chinese and foreign elite athletes.83% of the team in the entry didn't use acrobatic which shows the "fast" and "stable" characteristics,92% of the team use acrobatic in exit,walkover(back)is the main type,salto sideward in the next.2.In the stage of air display,the diversity of scores of mixed pair and group in the main stage of foreign elite athletes is superior to that of China,while trio are not quite different.The combination of scoring points in mixed pairis is straight arm height+ space change.The combination of scoring points in trio is straight arm height +airborne with 1/1 rotation.The scoring points in group are combined with space change+flexibity and propelling+airborne with 1/1 rotation.3.The use of the type of lift in China and foreign countries is the same.The mixed pair is using the type of turning,flipping and balancing,while trio is mostly using turning,balancing and flipping.Flipping and turning type lift is the main trend of Aerobics choreography.4.The time of lifts of elite athletes is consistent,approximately 7 to 10 s,but when the lift appears is not the same.Overall,the lifts of elite athletes in China appears later than foreign athletes.The number of base combination of trio in China is more than that in the foreign countries,and the group are the opposite.5.The mean value and the quality of the performance of lift in our country is lower than the foreign level.There are some minor errors such as the incorrect body shape and not fluent,physical ability of our athletes control needs to be improved.
