Research On The Sports Quality Level Of Chinese Junior Trampoline Athletes

Trampoline is a skill-dominated difficult-to-beautiful performance group.High,difficult,stable,accurate,and beautiful are its main characteristics and winning rules.Quality is the basis and guarantee of competitive tower.Good athletic quality not only determines the difficulty and height of development,but also improves the player's technical level and quality of movement.The Juvenile sportsmen are in the sensitization stage of growth and development.They need to combine the training rules of the project to focus on developing different sports qualities during the sensitive period of human development.Therefore,study the athletic quality of juvenile trampoline athletes,understand the differences between and within groups of juvenile trampoline athletes of different genders,explore their evaluation indicators and formulate evaluation standards so that juvenile trampoline athletes in China can accurately assess their level of athletic quality and set training goals for reference.This paper adopts the means of literature review,testing,mathematical statistics,comparative analysis,and logical analysis.123 young trampoline athletes in China's three national training camps in 2014,2017,and 2018 were investigated.Research on test indicators and results.The main conclusions are as follows:1.The traits of the quality training of youth trampoline athletes: Intervai training mainly adopts aerobic and anaerobic training approach;According to the sensitive period of sports quality,highlight the pertinence and effectiveness of training;Comprehensive development of sports quality,highlight strength training;Attach importance to the rehabilitation after training and make every effort to ensure the technical training.2.The athletic quality training of our country's young trampoline athletes should follow the principle of comprehensive development,systemic principle,differentiated treatment,coordinated development of athleticquality and technology.3.The factor analysis method was used to classify the athletic quality indicators of the three national trampoline training camps in 2014,2017,and2018 into three categories: strength factor,endurance factor,and speed factor.On account of this,indicator weights characteristics and laws of sports events were constructed.4.Young trampoline athletes in the same category,the athlete movement quality development level of different ages are not identical,among which the man athletes U10 group of lumbar muscle strength,U12 and U16 group man of lower limb strength athletes,female athletes quality all have no significant difference(P> 0.05),and the other groups of athletes have strong difference in waist and abdominal muscles,lower limb strength,back muscle strength,specific endurance,general endurance,(P <0.05).5.When comparing the athletic qualities of different groups of juvenile trampoline athletes,it was found that male athletes have significant differences in lower limb strength,general endurance,and general speed(P<0.05),while female athletes have significant differences in endurance(P<0.05).6.Multivariate stepwise regression analysis was performed on the athletic quality indicators of the three national trampoline training camps in2014,2017,and 2018.It was found that the team jumped back 10 times,eight-level abdominal bridge,200-meter run,standing long jump,10 air jump timing,30 The rice sprint run,10 straight backflip connections,two start in30 seconds,20 seconds in-situ backflip,30 vertical jump timings,and 30 second rib raises have significant impacts on the overall performance.7.Screening the athletic quality indicators and establishing an evaluation system for juvenile trampoline athletes in China can more accurately assess the athlete's athletic quality training level and state,and provide a reference for coaches to formulate training plans.Suggestions:1.Juvenile trampoline athletes have different differences betweendifferent genders,different ages,and different athletic qualities.Coaches should comprehensively master the training methods of various athletic qualities,understand the differences between athletes,and choose targeted training methods and means for athletes.2.The selection of sensitive indicators can simplify test the procedure of sports quality,improve the selection accuracy of trampoline athletes,and enable to conduct reasonable training of athletes.It is recommended to pay close attention to the changes in trampoline scoring elements and the physical damage of young athletes,and further practice the sensitive indicators.3.With the improvement of the scientific level of training,the evaluation standards establishment should be adjusted accordingly to improve the applicability of the standards.
