The Construction Of An Evaluation Index System For College Cricket Players' Special Physical Fitness

Research purposes:At present,there is a lack of theoretical research on college cricket players’ special physical quality.Coaches mainly rely on subjective experience to train college cricket players’ special physical quality,and lack certain scientific basis.The research is based on the measurement and evaluation theory and from a quantitative point of view,establishes an evaluation index system,a weight system and an evaluation standard system for college cricket players’ special physical quality,so as to provide a reference basis for scientific evaluation and diagnosis of cricket players’special physical quality.Methods:In this study,the Delphi method was used to determine the special physical fitness index of college cricket players,and the test method was used to test 109 college cricket players from 5 universities in Shanghai,1 university in Jiangsu province and 1 university in Gansu province to obtain 21 index data of special physical fitness.The coefficient of variation method was used to determine the index weight system,and the percentile method was used to establish the single score table and comprehensive evaluation table.Results:1)Establish a special physical fitness evaluation index system for college cricketers:five first-class indexes include special speed,special strength,special agility,special flexibility and special endurance quality;The 11 secondary indexes include displacement speed,reaction speed,movement speed,maximum strength,fast strength,strength endurance,direction changing ability,coordination ability,balance ability,trunk flexibility and aerobic endurance.There are 21 third-level indicators.The average number method is used to determine the weight of each index.2)In the first-class index of college cricketers’ special physical quality,the weight of special sensitive quality is 0.413,followed by the weight of special strength quality and special speed quality,which are 0.322 0.179 respectively.3)The evaluation standard of college cricket players’ special physical fitness has been established,which includes the evaluation standard of single index and comprehensive evaluation standard.The score of single index adopts a 5-point system,and the score is taken as a 5-grade dividing standard.The test score P10 is defined as 1 point(grade 1),P10-P25 as 2 points(grade 2),P25-P75 as 3 points(grade 3),P75-P90 as 4 points(grade 4),P90 and above as 5 points(grade 5).The comprehensive score is calculated by a weighted comprehensive average model.According to the size of the comprehensive score,a 5-level evaluation standard is also adopted.Through radar chart analysis,the advantages and disadvantages of individual indexes of college cricket players are diagnosed.Conclusion:The evaluation system of college cricketers’ special physical fitness includes index system,weight system and scoring evaluation standard system.The system is relatively complete,effective,reliable and practical,scientific and convenient,and can be used as a means to evaluate the special physical quality of cricketers.At the same time,it can also provide theoretical support and practical tools of measurement,diagnosis and monitoring for evaluating similar projects.It has high promotion value and is recommended to be used for reference in practice.
