Training Analysis Of "Light Speed Jump" In Speed Rope Skipping

In recent years,various large-scale rope jumping competitions at home and abroad are in full swing,which not only accelerates the development of rope jumping,but also receives the attention of the public.In these large-scale rope jumping competitions,there are Chinese rope skipping teams,among which,in the speed rope jumping events,it breaks the world record in many fields of speed rope skipping.The unique rope skipping method is closely related to the ability to extract gold and win silver and break the record.This rope jumping method has the intuitive characteristics of bending and squatting.The industry in rope jumping circle calls it "squat jump","bending jump method",etc.,but these terms are only a kind of expression of its external form,and it can not be defined scientifically and reasonably.From the analysis of the theory of circular motion in physics,it can be concluded that it is helpful to shorten the radius of rope body and improve the performance of rope jumping by taking proper bending method.Therefore,it is an urgent problem to define the concept of this method.This paper defines the light speed jump method reasonably after the research and analysis,and reveals the training methods,training methods and training principles adopted in the process of the training.It provides theoretical reference for other researchers and provides basis for rope skippers to use "light speed jump method".This paper takes the training research of "speed jump method" as the research object.The top six of the 30 second single roll and 3 minute single swing jump in the national rope skipping finals in 2018,2019 and 2020 were selected as the subjects of the study.By using many research methods,such as literature,questionnaire,interview,video analysis and mathematical statistics,the following conclusions are drawn through analysis,demonstration,reasoning and judgment(1)The method of light speed jump is a method to complete the speed rope jumping project,and its features include body shape and technical characteristics.The body shape features include body torso bending,lower extremity bending degree and body center stability;The technical features include the rope frequency,the alternate frequency of feet jump and the degree of matching.(2)The light speed jump method mainly adopts three methods: cordless training,rope free rope jumping training and rope skipping training in 30 seconds and 3 minutes.In the aspect of special skills,the three training methods are to establish the correct speed of light jump technique and the rope sense of the rope skipping;The special physical training mainly through these three methods to strengthen the speed,strength,endurance,flexibility,sensitivity of the light speed jump.(3)The tactical training of light speed jump in 3 minutes single swing rope jumping is mainly to plan and arrange the tactical distribution of athletes’ physical strength reasonably.In the 3 minutes of competition,the expected rope skipping times and physical strength distribution in the first minute,the second minute and the third minute shall be reasonably arranged.
