Construction Of The Evaluation Index System Of The Physical Quality Of The Excellent Women Sanda Athletes

Research objectives:In order to adapt to the trend,training theory is paid more and more attention to sport training,and relevant sports organizations or groups compete to carry out training services in training practice.This study intends to make detailed training plans for athletes’ physical quality through the study of different projects,especially the antagonistic projects,and assess athletes’ physical quality regularly according to the training plans,so as to To monitor the athletes and find out the problems in time,establish a set of fitness evaluation system suitable for excellent female Sanda athletes and give corresponding solutions,so as to continuously improve the training level of athletes.Research objects and methods:In the process of research object selection,the research group recruited 94 excellent female Sanda athletes from Beijing,Shanghai,Jiangsu,Henan,Anhui and other provinces(Mage = 21.46,SD = 3.05).Then,the author tries to use expert interview method,Delphi method and relevant statistical software to carry out mathematical statistical analysis,and selects the test indicators suitable for quantitative evaluation of the physical quality of excellent women Sanda athletes,and evaluates the feasibility of selecting indicators by combining literature review,expert guidance,case analysis and other evaluation methods.Then,factor analysis and statistical processing are carried out on the data indicators measured by the athletes,and the matrix of correlation coefficient of each indicator is obtained,as well as the contribution rate and cumulative contribution rate of the factors.According to the need of the data,select the factor whose cumulative contribution rate is more than 75% as the main influencing factor;finally,through the position percentage method,construct the physical quality evaluation standard of excellent female Sanda athletes.Research results:(1)Through three rounds of index selection and specific sample test,19 indexes are determined as the main indexes of the physical quality test and evaluation of the excellent female Sanda athletes.These indexes are respectively "30 seconds starting at both ends","20 seconds closing the belly and lifting the legs","30 seconds holding the sand man","800 meters","30 seconds punching","30 seconds later whip legs","8 ×4meters turn back running","15 seconds two punches and one leg","30 meters running","50 meters running","10 seconds original ground punching","10 seconds original whip legs","vertical fork","horizontal fork","deep squat","vertical Fixed long jump,horizontal push,left straight boxing strength,right straight boxing strength.(2)Through factor analysis,the main influencing factors of the physical quality of excellent female Sanda athletes are listed in the order of contribution rate from large to small: "endurance factor(20.22%)","strength factor(17.76%)","speed factor(16.62%)","sensitivity factor(10.74%)","flexibility factor(10.24%)".(3)Based on the analysis and processing of the athlete’s test data,the evaluation standards of seven levels of physical quality of excellent female Sanda athletes,namely"48kg","52kg","56kg","60kg","65kg","70kg" and "75kg",were established by using the position percentage method.Research conclusion:(1)19 physical fitness test indexes of excellent female Sanda athletes have been established.(2)The evaluation of excellent female Sanda athletes should be made from five aspects:endurance,strength,speed,sensitivity and flexibility,among which the dimensions of endurance,strength and speed are of great weight.(3)This paper establishes the scoring standard of the physical quality of the excellent female Sanda athletes,and gives the evaluation standard system of the physical quality of each excellent heavyweight female Sanda athletes.Research recommendations:(1)When evaluating the effect of physical quality training of excellent female Sanda athletes,we should focus on the evaluation of endurance and strength,speed,flexibility and sensitivity.(2)When selecting and evaluating athletes,coaches should pay attention to the evaluation criteria formulated according to the physical quality of excellent women Sanda athletes,evaluate the selected athletes in a targeted way,give full play to the advantages of athletes’ physical quality,and achieve twice the result with half the effort.
