A Comparative Study On The Time And Space Distribution Of The Complete Set Of Movements Of The Chinese And Foreign Elite Athletes In The Single Event Of Competitive Aerobics

In recent years,China’s competitive aerobics has developed rapidly,and the individual events such as three person aerobics and five person aerobics have achieved excellent results in the international competitions for many times.However,single person aerobics has always been a weak event in China.It has become the primary task of participating in the international competitions to improve the ranking of single person aerobics while stabilizing multi person aerobics.Based on the 2017-2020 competitive aerobics scoring rules,using the methods of literature,video analysis,expert interviews,mathematical statistics,this paper makes a multi-dimensional comparative analysis of 48 sets of videos in the 2018 World Championships,2018 championship and 2019 championship.Through comparative study to find out the differences between Chinese and foreign players in the creation of complete sets of competition,and then to provide practical reference for domestic players in the future creation of complete sets;from the space-time layout analysis of Competitive Aerobics single events can provide theoretical reference for the follow-up study of multi-person events,aerobic events and even other events of difficult and beautiful events.The conclusions are as follows:1.By comparing the three competitions,it is found that there is no obvious difference in the number of exercise units between domestic and foreign single players,and 8 to 9 exercise units are mostly used.Most of the domestic and foreign athletes arrange 45% of the difficult movements in the first third of the whole set,resulting in this phenomenon because the new cycle rule has 0.2 connection bonus points for the three connection difficult movements.In order to ensure the completion quality of the difficult movements,the coaches put the three connection difficult movements in front when arranging the whole set.Such arrangement is one of the main reasons that lead to the uneven distribution of exercise and difficult actions in the whole set.2.The average number of transition connections used by the top eight players in the 2018 World Championships is less than that of the two championships in China.In the international competition,the single transition connection is more complex and innovative,and it can show the main content of high quality.However,the domestic athletes mostly use the single and simple transition connection,and the complexity and diversity are not good.3.The top eight men’s singles players in the world championships use the most in the exercise arrangement of area 3,4,5,6,and the lowest in area 8.In the two domestic competitions,the use of plane area is incomplete in the movement of men’s singles.There are 7 players who use a certain area zero times.Among the three events,plane area 5 has the most difficult movement arrangement,which has the most direct relationship with area 5 in the most central part of the whole competition field division.Compared with the championship,the arrangement and division of the difficult movements of the world championship players in nine plane areas are more balanced.4.Compared with the 2018 World Championships,the maximum number of stops in a and B space of women’s singles in the two championships is against the rules,which is mainly reflected in the long stay time in B space,the coaches can’t reasonably arrange the corresponding actions according to the music melody,resulting in the long stay in a certain space,easy to cause visual fatigue,resulting in the poor artistry of the whole set of actions.
