Research On Construction And Application Of Special Physical Fitness Evaluation System For Young Athletes Of Taijiquan Team In Henan Province

At present,Henan Taijiquan team's first-line athletes are selected by the combination of Henan Taijiquan youth sports team and local merit recommendation.Before 2017,due to the small total number of athletes in training,in order to make reasonable use of limited training resources,training has not been arranged according to the age division of professional teams.With the continuous development of sports and the continuous improvement of training system,the selection method of Henan Taijiquan team's first-line athletes is gradually fixed among the young athletes trained by the Taijiquan team.The overall quality of young athletes has a great influence on the development of the first team.The selection of young athletes will determine the competitive level of Henan Taijiquan team in the future.Therefore,it is particularly important to do a good job in basic selection and improve the quality of young athletes.This study takes the special physical quality of young athletes as the research object,and determines specific research indicators from the perspectives of body shape,speed endurance,core stability,and movement quality.The special physical quality evaluation system thus constructed can provide basis for scientific selection of young athletes and early special training,and has important theoretical and practical significance for the cultivation of young athletes in Taijiquan sports and the arrangement of early special training.This study uses expert interview method to determine various indexes of selecting young athletes for special physical fitness,tests the selected young athletes,and uses factor analysis method to select 11 special physical fitness evaluation indexes that are easy to measure and have strong representativeness.Then,on the basis of determining the weight of evaluation indexes at all levels,a special physical fitness evaluation model for young Taijiquan athletes in Henan Province is established.1.After the parameter hypothesis test of the body shape test data of male and female second-line players,it is found that there is no significant difference in body shape between male and female second-line players of the same age group.Genetically speaking,the second-line players of this age group are still in the early stage of the acceleration of body growth,and the difference in body shape between the male and female second-line players has not yet formed significantly.Therefore,each index of body shape has little influence on the selection of second-line players,and the selection of indexes for male and female second-line players should be consistent.2.In the index evaluation system for the selection of special physical fitness for young athletes of Henan Taijiquan team,the three main factors respectively represent the three types of first-class indexes in the evaluation system,and the three types of first-class indexes are respectively action quality factor,speed endurance factor and core area stability factor.Among them,the action quality evaluation includes four secondary indexes: combined action,single beat foot,positive kick and flying foot.The evaluation of speed endurance includes four secondary indexes: touch high in situ,100 meters,400 meters and standing long jump.The stability evaluation of the core region includes three secondary indexes: cross jump,closed eye single leg balance and lower bridge.Principal component analysis was used to determine the weight coefficients of the first-level indexes,and range method was used to standardize the test data of the second-level indexes.Factor analysis was used to determine the weight coefficients of the second-level indexes.3.This evaluation standard is used to evaluate the scores of young athletes who have achieved the provincial and above-provincial junior championships in Henan Taijiquan team and other young athletes in the same team.The results show that there are great differences in speed endurance index and balance ability between male and female athletes.According to the individual scores of tested athletes,male athletes are better than female athletes in speed endurance and female athletes are better than male athletes in balance ability.The evaluation standard of special physical fitnesscompiled in this study is used to measure the comprehensive level of special physical fitness of young athletes in Henan Taijiquan team.It has good effect and certain practical value.
