The Construction Of Evaluation Index Of Special Flexibility Quality Of Rhythmic Gymnastics Students In Physical Education Colleges

At present,various sports colleges(including some comprehensive colleges)in our country have offered various levels of courses such as specialized,general,and optional courses in artistic gymnastics.As the difficulty level of rhythmic gymnastics in sports colleges and universities increases,the requirements for the competitive ability of students specialized in rhythmic gymnastics also become higher and higher.This is the inevitable development trend of rhythmic gymnastics in sports colleges in China.Among them,the special flexible quality as the basis and prerequisite for improving the competitive ability of artistic gymnastics becomes particularly important.However,in terms of flexibility quality training,there is still a big gap between China's current level and the power of artistic gymnastics;in terms of scientific research on evaluation and monitoring,most of the literature is only a research record of the relevant training methods of flexibility quality,and research on the assessment of flexibility quality And the literature on monitoring is scarce.This research starts with the evaluation content of the special flexibility quality of rhythmic gymnastics,and constructs the evaluation index of the special flexibility quality of the students specializing in rhythmic gymnastics in the sports colleges,in order to provide scientific theoretical reference for the supervision and control of the flexibility quality of the rhythmic gymnastics project and provide the coaches with the special flexibility quality.Provide reference for training and monitoring aspects,and provide the possibility to improve the efficiency of the special flexibility training of its students.In this study,through the literature data method,Delphi method and mathematical statistics method,and in accordance with the index construction scientific principle,comprehensive principle,independence principle and quantifiable principle,the preliminary assessment of the special flexibility quality evaluation index of the sports gymnastics students.The Delphi method was used to select 3 first-level indicators,6 second-level indicators,and 26 third-level indicators,and finally determined the evaluation index of the specific flexibility of the students specializing in rhythmic gymnastics in sports colleges;the fuzzy evaluation method and the percentage weight method were used to calculate Index weight coefficient,and sort and analyze its weight.The conclusion of this study is as follows:(1)The ranking of the first-level index weights is: lower limb flexibility> trunk flexibility> upper limb flexibility.Lower limb flexibility is the core and most necessary quality in the special flexibility of rhythmic gymnastics;trunk flexibility is the prerequisite for the formation of women's iconic beauty,and it is also the basis for mastering the technical movements of artistic gymnastics;the flexibility of upper limbs affects the malleability of artistic gymnastics And feminine.(2)The ranking of the second-level index weights is: hip flexibility> waist flexibility> shoulder flexibility> chest flexibility> ankle flexibility> wrist flexibility.(3)Hip flexibility is the primary quality of the special flexibility in rhythmic gymnastics.The three-level indicator "Forefoot heightening left and right longitudinal forks" is the most suitable for evaluating this quality;excellent waist flexibility is the completion of difficult movements and skill movements.And the basis for shaping beautiful shapes,the three-level indicator "stand up and stand down with legs" is the most suitable for evaluating this quality;the level of flexibility of the shoulders determines the fit between the upper limbs and the equipment,and the three-level indicator "stand up with legs and straight arms "Turn shoulder" is the most suitable for evaluating this quality;excellent chest flexibility can improve the quality of many styles and appearances.The three-level index "push-up flexion" is best for evaluating this quality;excellent ankle flexibility can extend the leg For the beauty,the three-level index "one-foot stand-up" is the most suitable for evaluating this quality;the level of wrist flexibility affects the quality of the completed device movements,and the three-level index "wrist flexion and flexion" is the most suitable for evaluating this quality.
