Research On The Characteristics Of Physical Skill Network Structure Of Aerobic Gymnastics’ Athletes

China’s Aerobic Gymnastics strength has always been in the forefront of the world,but the increasingly fierce competition environment has put forward higher requirements for athletes’ competitive ability,in order to be able to widen the gap with rivals in the competition and expand their competitive advantages,it is urgent to improve the level of athletic ability of athletes.Competitive ability,as a basic internal factor affecting performance,has an extremely complex structure,which requires us to probe into the relationship among its internal components,understand the characteristics and functions of the structure,and summarize the general law,it provides a scientific basis for re-understanding competitive ability and finding a proper training method.In this paper,the characteristics of the network structure of the physical skills of 15 competitive aerobics athletes in the aerobics team of Beijing University of Physical Education are taken as the research object,by using the methods of test,mathematical statistics and simulation and other research methods combined with the related knowledge of complex networks,the test data are described with statistical features,and the structural features of athletes’ physical skills network are analyzed,and the practical significance of training is explored,the conclusions are as follows:1.The average distance of 146 edges possessed by 27 nodes in the physical skill network of Aerobic Gymnastics’ athletes is relatively close,which shows the close relationship among the components of physical skill,the same or different attributes of the related nodes,the complexity of the connection among the nodes in the body skill network is explained.2.The core nodes obtained from the centrality analysis of network nodes from different perspectives can be used as the selection index of Aerobic Gymnastics items General endurance,specific flexibility and specific upper limb strength can be taken as the key content of physical fitness training,and their development level affects the quality of the whole network structure,as well as the evolution and upgrading of network structure.At the same time,the very few lower limb indexes in the core nodes reflect the relative lack of lower limb related content design in the National Aerobics Team Test Indexes.3.The Aerobic Gymnastics’ athletes physical skill network has the obvious module structure division,each module’s ability node presents the different function because of the attribute,the structure difference,between each module produces the connection through the intermediate node,show the overall level of athletic ability.4.The Aerobic Gymnastics’ athletes physical skill index plays different roles in the whole network and the sub-network,some nodes are connected with other nodes in the whole network,but they are independent nodes in the sub-network,no connection to other nodes.5.The structure characteristics of specific skill network of male and female athletes are different,which reflects the differences of sports ability between male and female athletes.
