Study On Visual Effects Of Collective Jazz In The World Cheerleading Championship Under The Guidance Of Rules

Jazz cheerleading is a kind of difficult to beauty project,with strong performance and appreciation,visual effect is an important content in the choreography of jazz cheerleading can not be missing.Cheerleading rules will jazz effect is divided into formation,level,transition movement and contrast movement and visual impact of five parts,jazz cheerleading not only needs the tacit cooperation between athletes but also needs novel and unique visual effects.A set with a perfect visual effect that not only reflects the overall level of the team,but also resonates with the judges and spectators.Therefore,visual effects are the key to whether a team can do well.In this paper,using the method of literature,interview,video analysis and mathematical statistics,the top eight teams in 2017,2018 and 2109 were carefully studied,and the arrangement of formation,hierarchy,contrast movement,transition movement and visual impact force in their visual effects were analyzed.To explore the future development trend of jazz cheerleading and provide scientific theoretical guidance for the arrangement of jazz cheerleading in China.The conclusions are as follows:1.The formation change is one of the important factors affecting the visual effect of a complete set.The number of participants is an important prerequisite for the formation change,and the more the number of participants,the stronger the visual effect.In terms of the arrangement,it is necessary to pay attention to the fluidity,appreciation and innovation of the formation.The more times the formation changes,the richer the visual effect will be.The use of the site features of "medium strong Angle and weak Angle" is more suitable for the concentrated expression of the visual effect.2.In the spatial changes of different levels,the superposition of space is the development trend of high-level team arrangement,which is mainly manifested as two-level space superposition interlaced with three-level space superposition.In the form of level completion,"partial completion" can increase the visual effect of level change on the basis of ensuring the quality of action.3.The utilization rate of contrast movements in sets of movements has reached 58%.More and more teams use contrast movements to present different visual effects,highlighting the sharp contrast and spatial contrast between different movements.The comparison groups were mainly composed of two groups,which were clean and clear.4.The use of transition movement highlights the fluency and visual appreciation of the whole set.It not only plays a connecting role between the preceding and the following in different movement types and styles,but also improves the completion specification of the movement.The transition action of the moving class uses more than the transition action of the fixed class to increase the visual dynamic sense of the whole set.5.Among the many factors that affect the visual impact,the main ones are lifting,collective maneuvering,turning and jumping.Lift movements combined with spatial changes will reflect different visual effects.Collective exercises,turns and jumps will produce strong visual impact in the context of music.The difficulty of turns is mainly based on the alac bar,which shows consistent visual performance through uniform difficulty movements.6.Clothing is the main external factor that affects the visual impact.Clothing color and style are designed according to the theme and musical features of the whole set.The color of clothing should be controlled in 2-3 kinds,and the matching of headwear can be added on the premise of not affecting the completion of the movement of the athletes.
