| Time and space are the foundation of art.The independent provisions of individual technical movements in the 2017 edition of the international scoring rules of artistic gymnastics show that artistic gymnastics projects require more delicate control and performance of time and space.As a key breakthrough project in China,artistic gymnastics has made some good achievements in recent years,but there are still some distances in technical level compared with the top teams in the world.With the methods of literature review,expert interview,video analysis,mathematical statistics and logical analysis as the main research methods,this paper analyzes the complete sets of actions of the top eight teams in the finals of the artistic gymnastics collective events in the 2020 Tokyo Olympic Games,and summarizes the development orientation of artistic expression forms of artistic gymnastics collective events.The results are as follows :(1)In the beginning and end of the set of movements,the world ’s best teams have concentrated capacity arrangements for difficult movements.The Chinese team interpreted the theme of the whole set of actions through the intersection of music rhythm and speed,and fully displayed the action in a certain space and time range.(2)Each team in the use of difficult movement space level combination is relatively single,the Chinese team is biased in favor of using single-layer space,leading good results in the uniformity,but teams like Bulgaria and others timely use of multi-level composite space,showing the rich diversity of space.(3)Athletes are required to accurately control time and space perception when completing collaborative movements.Athletes can form a variety of trajectories and spatio-temporal levels in the process of passing through the equipment above,middle and below.The Italian team uses the characteristics of the circle to arrange the form of expression through the equipment to complete the cooperative action.In the arrangement of time and space changes,the Chinese team not only shows the special ability of athletes,but also highlights the connotation and thought of the complete set.(4)The development direction of artistic gymnastics collective project art forms is to highlight the diversity of space-time changes in the novel and unique sets of movements,the integration of music and action highlights the theme style,and the form of formation changes presents the direction of space-time artistic beauty of sets of movements.The recommendations are as follows :(1)To meet the requirements of scoring rules as much as possible in a limited time,and to reasonably allocate the presentation time of difficulty movements,so as to maximize the artistic effect and the quality of completion.(2)In rhythmic gymnastics collective projects,multiple levels of space can be used to complete the action,so that the action forms a variety of hierarchical combinations,so as to present the three-dimensional action with varied and distinct levels.Based on high-level choreography,the technical level of equipment must be fully improved to ensure the quality and accuracy of action completion.(3)The transformation of formation must be combined with the use of equipment,and innovative arrangement should be made according to the characteristics of formation and movement to reflect the sense of time and space of rhythmic gymnastics in the process of formation and movement.China should reasonably and effectively use folk music and various forms of dance to show the artistic gymnastics in Chinese style to the world.(4)China ’ s rhythmic gymnastics in the arrangement process should be used in the whole ground area with novel,unique and varied forms of expression in time and space,reflecting its unique style in the general trend,showing the athletes ’ accurate equipment technology level.At the same time,athletes should give full play to their innovative consciousness and imagination,highlight the connotation of the theme of the complete set of movements in the change of time and space,and give the complete set of movements a higher artistic grade. |
